Valacyclovir

pronounced as (val ay sye' kloe veer)

Valacyclovir is used to treat herpes zoster (shingles) and genital herpes. It does not cure herpes infections but decreases pain and itching, helps sores to heal, and prevents new ones from forming.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Valacyclovir comes as a tablet to take by mouth. It is usually taken every 8 hours (three times a day) for 7 days to treat shingles. To treat genital herpes it is usually taken twice a day for 5 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take valacyclovir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Use this medication as soon as possible after symptoms appear.

Continue to take valacyclovir even if you feel well. Do not stop taking valacyclovir without talking to your doctor.

Before taking valacyclovir,

  • tell your doctor and pharmacist if you are allergic to acyclovir (Zovirax), valacyclovir, or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially cimetidine (Tagamet), probenecid (Benemid), and vitamins.
  • tell your doctor if you have or have ever had kidney or liver disease, problems with your immune system, human immunodeficiency virus infection (HIV), or acquired immunodeficiency syndrome (AIDS).
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking valacyclovir, call your doctor.

Take the missed dose as soon as you remember it, and take any remaining doses for that day at evenly spaced intervals. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to valacyclovir.

Do not have sexual intercourse when you can see the genital herpes lesions. However, genital herpes can be spread even when there are no symptoms.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription. If you still have symptoms of infection after you finish the valacyclovir, call your doctor.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

What is valacyclovir?

Valacyclovir is a prescription drug. It comes in the form of a tablet you take by mouth.

Valacyclovir is available as a brand-name drug called Valtrex. It’s also available as a generic drug. Generic drugs usually cost less than the brand-name version. In some cases, they may not be available in every strength or form as the brand-name drug.

This drug may be used as part of a combination therapy. This means you may need to take it with other medications.

Why it’s used

Valacyclovir is used to treat viral infections caused by a group of viruses called herpes simplex viruses. These infections include oral and genital herpes, shingles, and chickenpox.

  • Oral herpes causes cold sores. These are small, painful sores that you can get in or around your mouth. Cold sores can be spread by kissing or other physical contact with the infected area of the skin.
  • Genital herpes is a sexually transmitted disease. This means it’s spread through sexual contact. Symptoms include small, painful blisters on the genital area. You can spread genital herpes to your sexual partner even when you don’t have any symptoms. This drug is used to treat or prevent flare-ups of genital herpes in people with normal immune systems, or in people with HIV.
  • Shinglesis caused by the same virus that causes chickenpox (varicella zoster). Symptoms of shingles include small, painful blisters that appear on the skin. Shingles can occur in people who have already had chickenpox. It can also spread to people who have not had chickenpox before through contact with the infected skin.
  • Chickenpoxcauses an itchy rash of small, red bumps that can look like pimples or insect bites. The rash can spread almost anywhere on the body. Chickenpox can also cause flu-like symptoms, such as fever or tiredness. This drug is used to treat chickenpox in children ages 2 to18 years who have a normal immune system.

How it works

Valacyclovir belongs to a class of drugs called antiviral drugs. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

The herpes virus spreads in your body by creating more of its cells. Valacyclovir works by making it harder for the herpes virus to multiply (make more cells) in your body.

This drug does not cure herpes infections. The herpes virus may still live in your body after treatment. This means the infection may occur again at a later time even after the symptoms of the first infection are gone. However, this drug can help prevent such a re-infection at a later time.

Valacyclovir side effects

Valacyclovir oral tablet doesn’t cause drowsiness, but it can cause other side effects.

More common side effects

The more common side effects of valacyclovir can include:

  • headache
  • nausea
  • vomiting
  • dizziness
  • pain in your stomach area

If these effects are mild, they may go away within a few days or a couple of weeks. If they’re more severe or don’t go away, talk to your doctor or pharmacist.

Serious side effects

Call your doctor right away if you have serious side effects. Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency. Serious side effects and their symptoms can include the following:

  • Kidney failure. Symptoms can include:
    • severe drowsiness
    • urinating less than usual
    • swelling in your legs, ankles, or feet
  • Unusual mood or behavior. Symptoms can include:
    • aggressive behavior
    • unsteady or shaky movements
    • confusion
    • hallucinations
    • seizures
    • coma

However, because drugs affect each person differently, we cannot guarantee that this information includes all possible side effects. This information is not a substitute for medical advice. Always discuss possible side effects with a healthcare provider who knows your medical history.

Reducing your risk of spreading herpes

Using this medication daily may help lower the risk of spreading this disease to your sexual partner. However, you should not have sexual contact with your partner when you have any symptoms of an outbreak of genital herpes. Even if you use safer sex practices such as using a condom, you can still spread genital herpes. Talk with your doctor for more information about how to have safer sex.

Valacyclovir may interact with other medications

An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well. To help prevent interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking.

To find out how valacyclovir oral tablet might interact with something else you’re taking, talk to your doctor or pharmacist.

Valacyclovir warnings

This drug comes with several warnings.

Allergy warning

This drug can cause a severe allergic reaction. Symptoms can include:

  • trouble breathing
  • swelling of your throat or tongue

If you develop these symptoms, call 911 or go to the nearest emergency room.

Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal (cause death).

Warnings for people with certain health conditions

For people with kidney problems: Your kidneys clear this drug from your body. If you have kidney problems or a history of kidney disease, you may not be able to clear it from your body. This may increase the levels of the drug in your body and cause more side effects. This drug can also make your kidney function worse. To help prevent these problems, your doctor may prescribe a lower dosage of this drug for you.

For people with advanced HIV or a history of transplant: If you have advanced HIV or a history of bone marrow or kidney transplant, you may be at a higher risk of certain blood disorders. These conditions are called thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). They can result in severely low red blood cells and platelets in your body. TTP or HUS can cause death.

Warnings for other groups

For pregnant women: This drug is a category B pregnancy drug. That means two things:

  1. Research in animals has not shown a risk to the fetus when the mother takes the drug.
  2. There aren’t enough studies done in humans to show if the drug poses a risk to the fetus.

Talk to your doctor if you’re pregnant or planning to become pregnant. Animal studies do not always predict the way humans would respond. Therefore, this drug should only be used in pregnancy if clearly needed.

Call your doctor right away if you become pregnant while taking this drug.

For women who are breastfeeding: This drug may pass into breast milk and may cause side effects in a child who is breastfed. Talk to your doctor if you breastfeed your child. You may need to decide whether to stop breastfeeding or stop taking this medication.

For seniors: The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, a higher amount of a drug stays in your body for a longer time. This raises your risk of side effects.

For children: This drug has not been studied for use in treatment or prevention of herpes simplex virus (HSV) infection in newborn babies. The following are other age limitations for use of this drug:

  • Oral herpes (cold sores): This drug has been studied and approved for treatment of cold sores in children ages 12 years and older.

How To Know If You Have Yeast Infection

Valtrex side effects and interactions, and how to avoid them

If you’ve ever had shingles or cold sores, you know how uncomfortable these infections can be. Valtrex is an antiviral medication that can help relieve symptoms that come from viral infections like shingles or chickenpox. This article gives an overview of drug information including Valtrex side effects, warnings, and drug interactions that you should be aware of before taking the medication.

What is Valtrex?

Valtrex belongs to a group of medications called antivirals that work by slowing down the growth and spread of viruses like the herpes simplex, herpes zoster, and varicella-zoster viruses. Valtrex is the brand name for valacyclovir hydrochloride. The brand and generic versions of the medication are chemically the same, work the same way, and are equally effective at treating herpes virus infections.

Herpes virus infections include cold sores, genital herpes, shingles, and chickenpox. Valtrex can’t cure herpes infections, but it can treat symptoms like herpes sores and blisters. Valtrex is not an over-the-counter medication, so if you have a herpes infection, you’ll need a prescription.

It can take up to seven to 10 days for Valtrex to start working for some people, while others may feel relief from their symptoms after a day or two. The amount of time it takes your symptoms to go away will depend on your age, the severity of your symptoms, and your metabolism.

Valtrex for cold sores

Many people wonder whether Valtrex will stop cold sores from forming. Valtrex should be taken at the first signs of a cold sore (tingling, itching, burning) to prevent them from worsening and keep other cold sores from developing. However, it is not a cure for cold sores. It only treats them as a symptom of a viral infection.

Valtrex for genital herpes

Even if you’re taking Valtrex, it’s still possible to have an outbreak. If you’re taking Valtrex for recurrent genital herpes and have an outbreak, it’s important to avoid sexual contact with your partner to keep the virus from spreading to them. Even if you’re not experiencing an outbreak, using condoms is a good idea to prevent transmission. 

Also, if you’re wondering if your uninfected partner can take Valtrex to avoid becoming affected, the answer is no. Someone without herpes simplex virus shouldn’t take medication for something they don’t have. This could cause serious side effects or health problems. 

Common side effects of Valtrex

Taking Valtrex may cause side effects, such as:   

  • Headache 
  • Nausea
  • Stomach pain or abdominal pain 
  • Dizziness
  • Vomiting 
  • Weight gain
  • Irritability 
  • Tiredness
  • Trouble sleeping
  • Trouble concentrating
  • Loss of appetite
  • Skin rash
  • Bleeding gums
  • Sore throat 
  • Diarrhea  
  • Joint pain 

It’s unknown whether Valtrex causes other adverse effects like hair loss, weight gain, dry mouth, or any other symptoms not listed by the United States Food and Drug Administration (FDA). This is not a complete list of side effects. Other side effects may occur. Consult your healthcare provider if you have questions about side effects of Valtrex.

A frequently asked question about Valtrex is whether it will make you urinate more often. It won’t necessarily make you pee more, but you should drink plenty of water while taking Valtrex to help the kidneys process it as best they can. Therefore, this extra hydration can result in frequent urination.

Serious side effects of Valtrex

Although it’s rare, Valtrex can cause more serious side effects that may require medical attention, including:

  • Hallucinations
  • Aggressive behavior
  • Seizures
  • Confusion
  • Speech problems
  • Unusual bruising or bleeding
  • Depression
  • Low blood cell counts
  • Painful periods for women

If you’re taking Valtrex and have any of these symptoms, you should contact your doctor for medical advice as soon as possible. 

If you have any signs of an allergic reaction like difficulty breathing, hives, or swelling of the face, mouth, or throat, you should seek immediate emergency medical treatment.  

Other serious side effects that could potentially occur when taking Valtrex include: 

  • Inflammation of the liver
  • Renal toxicity
  • Kidney failure
  • A serious blood disorder called thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS) 

Some patients are more susceptible to these serious side effects than others. Consult your healthcare provider to find out if you’re at risk.

These side effects are very rare. Antiviral medicines are effective at treating viral infections, but after long-term use, they can eventually weaken the immune system by affecting immune cells. This is typically only an issue for seniors and people with weakened immune systems. Even though it’s not typically taken for long periods of time, if your doctor does want you to take it long term, then that’s okay. Some studies have even shown that the long-term use of Valtrex is well-tolerated for healthy individuals.

If you start to have side effects from Valtrex and are thinking about stopping the medication, you should call your doctor before doing so. Abruptly stopping Valtrex can cause new side effects or worsen symptoms. If you stop Valtrex before you’re supposed to, your viral infection may get worse because the medication hasn’t had the opportunity to work properly. 

Valtrex warnings

Even though Valtrex is very effective at treating herpes virus infections, it shouldn’t be taken by everyone.

Underlying health conditions

You should talk with your doctor before taking Valtrex if you have any of the following medical conditions:

  • HIV: Having HIV suppresses the immune system and increases the probability of getting other medical conditions. People with HIV who take Valtrex significantly increase their risk of getting TTP/HUS, a serious blood disorder.   
  • Kidney or bone marrow transplants: If you’re taking Valtrex and are about to have a bone marrow or kidney transplant, you should talk with your doctor. Your risk of getting TTP/HUS will be significantly increased if you take Valtrex during your transplant process.
  • Kidney problems or kidney disease: People with kidney problems or kidney disease could experience a worsening of symptoms or kidney failure if they take Valtrex.

Because of its potential to negatively affect the kidneys, some people wonder if Valtrex is also hard on the liver, but studies have shown that it’s rarely associated with mild liver injury that resolves quickly.    

Age restrictions

If you are over the age of 65, it’s best to consult with your doctor before taking Valtrex. Elderly adults may have a higher risk of experiencing side effects and are more likely to have kidney problems because of it. This doesn’t mean that you can’t take Valtrex over the age of 65. Your doctor may simply recommend a lower dose.

Pregnancy and breastfeeding

Pregnant women should talk with a healthcare professional if they’re considering taking Valtrex to learn how it might affect their pregnancy. “Through laboratory testing, Valtrex had no effects on the fetus; nevertheless, Valtrex was not adequately tested with pregnant people,” says Vikram Tarugu, MD, a gastroenterologist and the CEO of Detox of South Florida. “The safety of Valtrex has not been proven in breastfeeding babies.” Women who are breastfeeding should consult their doctor about other approaches to feeding.  

Valtrex interactions

Taking Valtrex at the same time as certain other medications may cause additional side effects or complications. You should talk with your doctor before taking Valtrex if you’re on any of these medications:  

  • Foscarnet 
  • Acyclovir 
  • Famciclovir
  • Nephrotoxic agents 
  • Bacitracin 
  • Methotrexate 
  • Cancer medications
  • Arthritis medications 
  • Medications used to prevent organ transplant rejections 
  • Also, talk to your doctor if you’ve recently had a varicella virus vaccine (live) or zoster virus vaccine (live, Zostavax—not Shingrix)

Bring a complete list of all the prescription drugs and supplements you’re taking to your healthcare provider, so he or she can decide if Valtrex is right for you.     

There are currently no known interactions between Valtrex and grapefruit or grapefruit juice, which can sometimes interfere with how much of a drug stays in the body at one time. 

Alcohol, on the other hand, is best avoided while taking Valtrex. This is because when alcohol and Valtrex are combined, they can cause excessive drowsiness and dizziness.  

When it comes to caffeine and Tylenol, two of the things most likely to be consumed while on Valtrex, it’s okay to take them unless told otherwise by a medical professional.

How to avoid Valtrex side effects

1. Take the right dose at the right time of day

This is the best way to avoid Valtrex side effects. Here are the standard doses of Valtrex for adults and children:    

Valtrex dosages

Cold soresAdults2 g twice daily for one day taken 12 hours apart
Cold soresChildren (12 years and older)2 g twice daily for one day taken 12 hours apart
ShinglesAdults1 g three times daily for 7 days
ChickenpoxChildren with normal immune function (ages 2 years to <18 years)Dose is based on weight (20mg/kg) and given 3 times daily for 5 days. The total dose should not exceed 1 gram three times daily for 5 days.
Genital herpes (initial episode)Adults1 g twice daily for 10 days

These dosages are only general guidelines. If your doctor prescribes Valtrex differently, then you should follow their instructions. Valtrex is most effective when started as soon as symptoms begin, so see your doctor immediately if you have symptoms. It’s safe to take Valtrex every day as long as you’ve been instructed to do so.

If you miss a dose of Valtrex, you should take the next dose as soon as possible. Taking your missed dose as soon as you remember you’ve missed it will help keep your herpes infection from worsening. Taking two doses at one time can cause serious side effects, so if you’ve missed a dose, only take one dose when you remember. However, if it’s almost time for your next dose, skip the missed dose and resume your normal schedule. 

It’s also important to remember that Valtrex has an expiration date just like any other medication. Look for the expiration date on the prescription label to see how long your particular version of Valtrex is good for. Expired medications can be less effective and risky to take. Some medications are also sensitive to heat, so be sure to store Valtrex at room temperature.

2. Take Valtrex with a full glass of water.

This helps your kidneys process it more efficiently. Once it’s been taken, Valtrex starts working to treat symptoms right away. Even though it starts working right away, it may take several days for you to notice a difference in your symptoms.

3. Switch medications if necessary.

Acyclovir (brand name Zovirax) is another antiviral drug that can be used to treat herpes virus and varicella-zoster virus infections. Neither medication is better than the other, but if someone can’t tolerate Valtrex or has an underlying medical condition that prevents them from taking it, acyclovir is another good option.  You can compare the medications here.

What to know about valacyclovir

We include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process.

Valacyclovir is a prescription drug available in oral tablet form. It is the generic version of the brand-name drug Valtrex. Doctors prescribe valacyclovir to treat infections caused by the herpes virus, including genital herpes.

Below, we take a closer look at this drug and outline how it differs from acyclovir. We also look at the drug’s side effects and warnings.

About the herpes virus

There are two types of the herpes simplex virus: HSV-1 and HSV-2.

HSV-1 is the cause of most cold sores, while HSV-2 is involved in most cases of genital herpes. However, both HSV-1 and HSV-2 can cause herpes infections in either location.

A person can contract an HSV-1 infection through oral-to-oral contact such as kissing. It is also to pass on the HSV-1 virus through oral-to-genital contact, which results in genital herpes. People are more contagious when they have a flare-up of the virus and have active sores.

People usually get the HSV-2 virus through sexual contact and can pass on an HSV-2 infection even if they do not have obvious symptoms. Condoms can the risk of passing on genital herpes, but this is not guaranteed.

Another form of herpes virus is called the herpes zoster virus, which is more commonly known as shingles. The varicella-zoster virus (VZV), which is also known as chickenpox, lays dormant in the body after the initial infection. In some people, the virus may .

A person can only become infected with shingles if they have previously had chickenpox. However, someone who has never had chickenpox can become infected with the virus through someone with shingles if they have direct contact with open sores.

Learn more about shingles and how it is spread here.

How valacyclovir is used? 

Valacyclovir is only available by prescription. It treats the following viral infections:

  • oral herpes or cold sores
  • genital herpes
  • varicella-zoster virus (VZV) or chickenpox
  • herpes zoster or shingles

This antiviral drug can also help reduce the risk of transmitting genital herpes to another person.

There is an ongoing study to look into valacyclovir’s potential use for treating mild Alzheimer’s disease in people with HSV-1 or HSV-2.

Side effects

Possible mild side effects of taking valacyclovir include:

  • headache
  • nausea and vomiting
  • upset stomach
  • dizziness

Uncommon side effects include:

  • painful menstruation
  • depression
  • joint pain
  • low blood cell counts

In some cases, individuals may experience severe side effects such as kidney failure and nervous system problems.

Warnings

There are some warnings that come with valacyclovir.

  • People with advanced human immunodeficiency virus (HIV) and those who have recently received a bone marrow or kidney transplant may be at risk for blood disorders such as thrombotic thrombocytopenic purpura (TTP) or hemolytic uremic syndrome (HUS).
  • Some people may experience central nervous system side effects, such as confusion and hallucinations. This side effect is more likely in older adults.
  • Valacyclovir may cause an allergic reaction in some people. If a person has an allergic reaction to valacyclovir, they should seek emergency medical care.
  • Valacyclovir can interact with certain medications. People should talk to their doctor about potential interactions with any drugs, herbs, vitamins, or supplements they are taking.

Valacyclovir vs. Acyclovir

Both valacyclovir and acyclovir treat viral herpes infections and both are equally effective. The table below shows some key differences.

Both of these generic medications are covered by most medical insurance plans. However, a person should check with their plan provider to confirm coverage.

Where to buy online

A person can only purchase valacyclovir with a prescription from a doctor, but there are many online pharmacies that offer fast and efficient ways to receive medications.

When ordering online, websites such as Roman require that a person do one of the following:

  • Already have a prescription to upload.
  • Complete a questionnaire on symptoms and provide visual identification for a medical professional to review.
  • Provide the contact details for their doctor, so the company can contact them to verify the prescription.

Some companies may have other rules that individuals must follow to receive their prescribed medication.

Some companies, such as Lemonaid, offer valacyclovir in a way that the U.S. Food and Drug Administration (FDA) has not approved, meaning that the way the company prescribes the medication is not how the label recommends. This is known as off-label use. A person should consider contacting their doctor before using medications in this way.

Difference between brand name and generic options

The between brand-name and generic drugs is the cost. Generic versions of drugs may also look different from their brand-name counterparts. Generic medicines have the same active ingredients as brand-name drugs and both types are FDA approved.

Once an initial patent for a drug expires, companies can begin selling generic forms. Because repeat clinical testing is not necessary for generic medications, they cost less.

The brand name for valacyclovir is Valtrex. Acyclovir, a similar antiviral, goes by the brand name Zovirax.

Summary

Valacyclovir is an effective antiviral treatment for chickenpox, shingles, oral herpes, and genital herpes. While the drug cannot cure genital herpes, it can help a person manage their symptoms. It can also reduce instances of transmission.

If a person suspects they have a viral herpes infection, they should see a doctor. With shingles, treatment is necessary to get rid of the infection and prevent complications.

Aug 14,  · Miconazole is an antifungal medication used, according to the National Institutes of Health, to treat skin and yeast fungal infections. **This product is available over the counter as a cream and as a suppository and is indicated for use once a day for three to seven days, depending on the concentration of the active ingredient.

There are insufficient data on the use of Valacyclovir regarding miscarriage or adverse maternal or fetal outcomes see Data. There are risks to the fetus associated with untreated herpes simplex during pregnancy see Clinical Considerations. In animal reproduction studies, no evidence of adverse developmental outcomes was observed with Valacyclovir when administered to pregnant rats and rabbits at system exposures AUC 4 rats and 7 rabbits times the human exposure at the maximum recommended human dose MRHD see Data.

The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U. A primary herpes occurrence during the first trimester of pregnancy has been associated with neonatal chorioretinitis, microcephaly, and, in rare cases, skin lesions.

In very rare cases, transplacental transmission can occur resulting in congenital infection, including microcephaly, hepatosplenomegaly, intrauterine growth restriction, and stillbirth.

Co-infection with HSV increases the risk of perinatal HIV transmission in women who had a clinical diagnosis of genital herpes during pregnancy. Data Human Data: Clinical data over several decades with Valacyclovir and its metabolite, acyclovir, in pregnant women, based on published literature, have not identified a drug-associated risk of major birth defects.

There are insufficient data on the use of Valacyclovir regarding miscarriage or adverse maternal or fetal outcomes. The Acyclovir and the Valacyclovir Pregnancy Registries, both population-based international prospective studies, collected pregnancy data through April The Acyclovir Registry documented outcomes of 1, infants and fetuses exposed to acyclovir during pregnancy with earliest exposure during the first trimester, during the second trimester, during the third trimester, and 2 unknown.

The occurrence of major birth defects during first-trimester exposure to acyclovir was 3. The Valacyclovir Pregnancy Registry documented outcomes of infants and fetuses exposed to Valacyclovir during pregnancy 28 with earliest exposure in the first trimester, 31 during the second trimester, and 52 during the third trimester.

The occurrence of major birth defects during first-trimester exposure to Valacyclovir was 4. Available studies have methodological limitations including insufficient sample size to support conclusions about overall malformation risk or for making comparisons of the frequencies of specific birth defects.

No adverse embryo-fetal effects were observed in rats and rabbits at acyclovir exposures AUC of up to approximately 4 rats and 7 rabbits times the exposure in humans at the MRHD. No significant adverse effects were observed in offspring exposed daily from before birth through lactation at maternal exposures AUC of approximately 6 times higher than human exposures at the MRHD.

Lactation Risk Summary Although there is no information on the presence of Valacyclovir in human milk, its metabolite, acyclovir, is present in human milk following oral administration of Valacyclovir.

Based on published data, a mg maternal dose of Valacyclovir tablets twice daily would provide a breastfed child with an oral acyclovir dosage of approximately 0. There is no data on the effects of Valacyclovir or acyclovir on the breastfed child or on milk production. Data Following oral administration of a mg dose of Valacyclovir tablets to 5 lactating women, peak acyclovir concentrations C max in breast milk ranged from 0.

The acyclovir breast milk AUC ranged from 1. A mg maternal dose of Valacyclovir tablets twice daily would provide a breastfed child with an oral acyclovir dosage of approximately 0. Unchanged Valacyclovir was not detected in maternal serum, breast milk or infant urine. Pediatric Use Valacyclovir tablets are indicated for treatment of cold sores in pediatric patients aged greater than or equal to 12 years and for treatment of chickenpox in pediatric patients aged 2 to less than 18 years [see Indications and Usage 1.

The use of Valacyclovir tablets for treatment of cold sores is based on 2 double-blind, placebo-controlled clinical trials in healthy adults and adolescents aged greater than or equal to 12 years with a history of recurrent cold sores [see Clinical Studies The use of Valacyclovir tablets for treatment of chickenpox in pediatric patients aged 2 to less than 18 years is based on single-dose pharmacokinetic and multiple-dose safety data from an open-label trial with Valacyclovir and supported by efficacy and safety data from 3 randomized, double-blind, placebo-controlled trials evaluating oral acyclovir in pediatric subjects with chickenpox [see Dosageand Administration 2.

The efficacy and safety of Valacyclovir have not been established in pediatric patients: aged less than 12 years with cold sores aged less than 18 years with genital herpes aged less than 18 years with herpes zoster aged less than 2 years with chickenpox for suppressive therapy following neonatal HSV infection.

The pharmacokinetic profile and safety of Valacyclovir oral suspension in children aged less than 12 years were studied in 3 open label trials. No efficacy evaluations were conducted in any of the 3 trials.
