Does Valtrex Stop Herpes Outbreaks

When To See A Medical Provider

An All Natural OTC Topical Product for Genital Herpes Outbreak Symptoms

If you notice any serious adverse effects while taking Valtrex, seek medical advice immediately. You should also see a medical provider if:

  • You have frequent cold sore outbreaks
  • The cold sores dont heal within ten days of taking Valtrex
  • There are sores in your mouth, or you have swollen gums
  • You have a weakened immune system
  • You think your cold sores might be something else
  • You have questions concerning your medication

Dangers To Children And Babies

Cold sores can be fatal to newborn babies and dangerous for older babies or children.

Do not kiss babies if you have a cold sore. It can lead to neonatal herpes.

In rare situations, cold sores can cause complications for older babies and children. The most serious of these is encephalitis, when the virus causes an inflammation of the brain.

Why Is This Medication Prescribed

Acyclovir is used to decrease pain and speed the healing of sores or blisters in people who have varicella , herpes zoster , and first-time or repeat outbreaks of genital herpes . Acyclovir is also sometimes used to prevent outbreaks of genital herpes in people who are infected with the virus. Acyclovir is in a class of antiviral medications called synthetic nucleoside analogues. It works by stopping the spread of the herpes virus in the body. Acyclovir will not cure genital herpes and may not stop the spread of genital herpes to other people.

A Pharmacist Can Help With Cold Sores

A pharmacist can recommend:

  • creams to ease pain and irritation
  • antiviral creams to speed up healing time
  • cold sore patches to protect the skin while it heals

You can buy electronic devices from pharmacies that treat cold sores with light or lasers.

Some people find these helpful, but there have not been many studies to confirm if they work.

If you regularly get cold sores, use antiviral creams as soon as you recognise the early tingling feeling. They do not always work after blisters appear.

    Herpes Drugs Don’t Stop Herpes Shedding

    Got Genital Herpes? You’re Still Infectious, Even if Drugs Cut Symptoms

    Even when they don’t have an active herpes outbreak, people who carry genital herpes viruses are at risk of infecting their sex partners. With the discovery of drugs that prevent herpes outbreaks, there was hope that the drugs would also prevent herpes transmission. But there’s been troubling evidence that this may not be true.

    Now University of Washington researcher Christine Johnston, MD, and colleagues show that people with no herpes symptoms often shed infectious genital herpes virus — even while taking very high doses of anti-herpes drugs.

    “Short episodes of genital shedding occur frequently with antiviral therapy, even for high-dose regimens,” Johnston and colleagues report. “These breakthrough episodes are typically , last several hours, and occur at much the same rate irrespective of antiviral dose.”

    One in 5 Americans and Europeans carries HSV-2, the virus that causes most cases of genital herpes HSV-1 causes some cases. Most people have few, if any, of genital herpes’ painful symptoms: blisters on or around the genitals or rectum.

    There’s no cure for herpes infections. That’s because herpes viruses travel up nerves to take up latent form in the nerve root. Powerful anti-herpes drugs — acyclovir , famciclovir , and valacyclovir — prevent most outbreaks in most people. But they don’t eliminate virus hiding in nerve cells.

    Types Of Antiviral Drugs

    There are three oral antivirals recommended for the treatment of oral or genital herpes:

    Famvir, 250 mg Twice daily

    Preventing genital herpes recurrence is important as it reduces the risk of HIV. According to the CDC, having an active genital herpes infection increases the risk of HIV by 200% to 300%.

    How To Take Aciclovir Tablets

    The dosage and duration you need to take oral aciclovir will depend on:

    • Whether you have any other conditions
    • Other medication you are taking
    • Your reaction to the first dose of treatment

    Below are some general aciclovir dosage guidelines for genital herpes. Always take medication as directed by your doctor or pharmacist:

    • The first episode of genital herpes: Take 200 mg of aciclovir five times a day or 400 mg three times a day for 5 days
    • Further outbreaks of genital herpes: Take 800 mg of aciclovir three times a day for 2 days, or 200 mg of aciclovir five times a day for 5 days, or 400 mg of aciclovir three times a day for 3â5 days
    • Suppressive therapy: Take 400 mg of aciclovir twice a day, or 200 mg four times a day, increasing to 400 mg three times a day. A doctor will reassess treatment every 6â12 months to check whether there is a reduction in outbreaks

    You should swallow one tablet with water at the intervals your doctor or pharmacist prescribes. You must not skip doses and should complete the treatment course, even if you start to feel better.

    If you forget to take a dose of aciclovir, take it as soon as you remember. However, if it is nearly time to take the next dose, skip the missed dose and continue taking the next dose.

    Myth #: You Cant Get Herpes If Youre Not Sexually Active

    Herpes can be passed from skin-to-skin contact that isnât sexual in nature, Hawkins tells me. âIf you look at the leotards that wrestlers wear, if you have upper thigh genital herpes in an area thats low enough that it shows under the leotard, someone can get it, too,â Hawkins tells me.

    With that said, Hawkins tells me you donât need to worry about getting it from trying on a swimsuit or sharing a towel, because the virus doesnât live outside of the body for long. âNow if youre trying on bathing suits without any underwear underneath, there are plenty of wonderful infections that you can get even if herpes is not one of them,â she says. âPeople are still strongly advised to make sure theyre using proper hygienic options.â

    What Are The Causes Of Herpes Infection

    The various causes of herpes infection are:

    • Herpes infection spreads from one person to another through direct skin-to-skin contact and is highly contagious.
    • Touching or kissing is the main cause of HSV 1 transmission, whereas, sexual contact is the main cause of HSV 2 transmission.
    • If a healthy person shares personal items like toothbrushes, utensils, spoons, etc. with an infected person, then he/she may also get infected.
    • Herpes infection can also spread through the eyes.
    • This infection can spread by touching the mouth sores of an infected person.
    • Having sex without protection can lead to herpes infection of the genitals.

    How Does Valtrex Work

    Generic Valtrex For Herpes Infections

    Valtrex belongs to a class of drugs called nucleoside analogs that mimic one of the building blocks of DNA. It stops the spread of herpes virus in the body by preventing the replication of viral DNA that is necessary for viruses to multiply. Other drugs in the same class include acyclovir and famciclovir . Valacyclovir is actually a âprodrug,â in that it is not active itself. Rather, it is converted to acyclovirin the body, and it is the acyclovir that is active against the viruses. Valacyclovir, therefore, is active against the same viruses as acyclovir, but valacyclovir has a longer duration of action than acyclovir, and, therefore, can be taken fewer times each day.

    The FDA approved valacyclovir in 1995.

    Some Important Facts Affecting The Risk Of Herpes Transmission

    • Herpes is transmitted through skin-to-skin contact
    • The first outbreak is the most contagious
    • There is a greater statistical chance of passing herpes when youâve been recently diagnosed whether you have symptoms or not
    • Herpes infects skin areas that are thin and moist because itâs easier for the virus to penetrate those areas. For that reason, females are three times more likely to be infected than males
    • Younger people having casual sex are more likely to contract herpes
    • HSV-1 in the genital area recurs less often than HSV-2
    • Being positive for HSV-2 gives some protection against getting HSV-1. The opposite is not true
    • If a person with one type of herpes acquires a different type, the flare-up symptoms are milder
    • Sex toys should not be shared. But if they are shared, they should be cleaned with water and soap before being used

    What Makes Valtrex Unique

    In addition to Valtrex, there are 2 other antiviral medications that are used for cold sores: acyclovir and famciclovir . All 3 have been shown to be more effective at treating cold sores than OTC creams or ointments, says Beth Bryan, PharmD. Shes a pharmacist and the owner of Surgoinsville Pharmacy in Surgoinsville, Tennessee.

    That said, Valtrex is often the first choice because it has better bioavailability, says Daniel Breisch, PharmD. Hes a pharmacist at Mountain View Pharmacy in Bountiful, Utah. That means you can take less of the drug and have superior outcomes, he says.

    Home Remedies For Herpes

    In addition to taking medication, many people treat their herpes virus infections with natural and home remedies. Natural remedies shouldnt be a substitute for antiviral drugs, but many people find that they help heal painful sores and blisters.

    Here are some natural and home remedies that could possibly help your herpes virus infection:

    • Drinking echinacea tea. Echinacea is an herb. Echinacea tea can boost the immune system, helping the body fight off virus outbreaks that manifest as cold sores, shingles, genital herpes, or chickenpox.
    • Using hydrogen peroxide for cold sores. Hydrogen peroxide can clean cold sores and help them heal faster because of its antiseptic properties.
    • Eating foods rich in L-lysine. Some studies suggest that the amino acid L-lysine can help keep the herpes virus from replicating. Taking a lysine supplement or eating foods that contain L-lysine like vegetables, legumes, and fish can help keep your herpes virus infection from worsening.
    • Applying cool compresses. For genital herpes, applying a cool compress to the affected area can help alleviate pain and itching that come from sores and blisters.

    Herpes And Newborn Infants

    Herpes infection in a newborn can cause a range of symptoms, including skin rash, fevers, mouth sores, and eye infections. If left untreated, neonatal herpes is a very serious and even life-threatening condition. Neonatal herpes can spread to the brain and central nervous system, causing encephalitis and meningitis. It also can lead to intellectual disability, cerebral palsy, and death. Herpes can also spread to internal organs, such as the liver and lungs.

    Infants infected with herpes are treated with acyclovir, an antiviral drug. They usually receive several weeks of intravenous acyclovir treatment, often followed by several months of oral acyclovir. It is important to treat babies quickly, before the infection spreads to the brain and other organs.
