A first outbreak of genital herpes can cause a long illness with severe genital sores and can also affect the nervous system. Even if your first episode of herpes is mild, you may have severe or prolonged symptoms later. For this reason, the Centers for Disease Control and Prevention recommends that everyone who has a first episode of genital herpes take antiviral drugs.

Almost everyone who has one episode of genital herpes caused by HSV-2 also has later breakouts of sores. Later episodes are less common if your case of genital herpes is due to an HSV-1 infection.

The frequency of genital herpes outbreaks slows down over time in many people.

Is There A Cure Or Treatment For Genital Herpes

There is no cure for genital herpes. However, daily use of antiviral medicines can prevent or shorten outbreaks. Antiviral medicines also can reduce the chance of spreading it to others.

Though several clinical trials have tested vaccines against genital herpes, there is no vaccine currently available to prevent infection. One vaccine trial showed efficacy among women whose partners had HSV-2, but only among women not infected with HSV-1. Efficacy was not observed among men whose partners had HSV-2. Another trial testing the same vaccine showed some protection from genital HSV-1 infection, but none from HSV-2.

Herpes Simplex 1 and 2 Experimental Treatment

Scientists have studied alternative treatments, like herbal extracts and nutritional supplements, based on some genital herpes patients’ claims that they help relieve symptoms. Some study results have been promising, others discouraging.

Many people say that an extract of the echinacea plant helps boost the immune system’s ability to fight the genital herpes infection. Some say it decreases the frequency and severity of genital herpes outbreaks. Researchers in the U.K. compared the effect of echinacea with that of a placebo. They gave echinacea to 50 people with genital herpes for six months and a placebo for another six months. There was no significant difference in the number of herpes outbreaks during the two periods.

Another study showed that an ointment containing propolis, a waxy substance that honeybees make, may help genital herpes sores heal. Sores healed faster for people using the propolis ointment than in those using ointments containing the antiviral drug acyclovir or a placebo. The ointment was applied to herpes sores four times a day. After 10 days, 24 of the 30 people using propolis ointment said their sores healed, compared with 14 of the 30 people using acyclovir ointment and 12 of the 30 using a placebo.

Researchers have also found that the herb Prunella vulgaris, and an edible mushroom, Rozites caperata , contain chemicals that fight both the oral herpes virus and the genital herpes virus .

  • With dry hands, remove one delayed-release tablet from the container.
  • Gently apply the tablet to the upper gum area as high as it will go on your gum above one of your incisor teeth on the side of your mouth with the cold sore. Do not apply it to the inside of the lip or cheek.
  • Hold the tablet in place for 30 seconds.
  • If the tablet does not stick to your gum or if it sticks to your cheek or the inside of your lip, reposition it to stick to your gum. Leave the tablet in place until it dissolves.
  • Do not interfere with the placement of the tablet. Check to see if the tablet is still in place after eating, drinking, or rinsing your mouth.
  • If the delayed-release buccal tablet comes off within the first 6 hours of application, reapply the same tablet. If it still will not stick, then apply a new tablet. If you accidentally swallow the tablet within the first 6 hours of application, drink a glass of water and place a new tablet on your gum.

    What Is The Best Treatment For Herpes

    • What is the best treatment for herpes?

    In 2015 the World Health Organization said two-thirds of the world population have oral herpes. Every person has at least once asked himself what is the best treatment for herpes. Not because it is dangerous, but because it hurts and is unaesthetic.

    We know that cold sores have nothing to do with a cold. Though they may appear exactly when we catch a cold, like the cherry on top of a cake, the cold is not what causes it.

    Cold sores mark an outburst of infection with Herpes Simplex Virus which gives us the disease called Herpes labialis.

    Also called fever blisters, they can show up anywhere on your body: outside of your mouth and lips, nose, cheeks, or fingers. I have seen pictures online that completely turned my stomach upside down. So gross, so hideous and surely very painful. But of course these are cases when herpes is associated with other diseases or/and on an immunodeficient system.

    Generally the episodes of herpes labialis are self-limiting conditions and would normally heal within 10 to 14 days, if left untreated. But today people dont let them heal by themselves and immediately apply something on it. Like Acyclovir.

    The downside of this drug is that it works best ONLY when started at the first sign of an outbreak. It may not work as well if you delay treatment. And thats not such a good thing, as you may be in an area where you cannot find a pharmacy.

  • The bottom line

    • Aciclovir, valaciclovir, and famciclovir are similarly effective in healing lesions, and in reducing duration of symptoms and of viral shedding, in genital herpes

    • Long term suppressive treatment is safe and effectively reduces recurrences in genital and orolabial herpes however, it does not completely eliminate recurrences or risk of transmission of genital herpes simplex virus infection to sexual partners

    • In older patients, and those with impaired renal function or taking nephrotoxic drugs, monitor renal function closely and consider using lower doses owing to the risk of renal toxicity, intravenous aciclovir requires good hydration

    • Suppressive aciclovir or valaciclovir in the last weeks of pregnancy reduces clinical disease in the mother and transmission to the baby at the time of delivery but does not completely eliminate the risk of neonatal transmission

    • Neonates with central nervous system infection require high dose intravenous aciclovir for 21 days, and suppressive treatment with valaciclovir improves neurodevelopmental outcomes

    When To Talk With A Doctor

    Herpes isnt curable, but it can be treated with antiviral medications. These medications can reduce the severity of an outbreak.

    If you suspect you have herpes, make an appointment with a doctor. Its also a good idea to talk with your doctor about a herpes screening if:

    • your current or previous sexual partner has herpes
    • youre planning to have sex with a new partner
    • you had a risky sexual encounter

    If youve already been diagnosed with herpes and youre currently experiencing an outbreak, the outbreak might go away without causing complications and without treatment.

    However, its wise to make an appointment with your doctor if:

    • the outbreak is particularly painful or unbearable
    • youre experiencing symptoms of other STIs
    • youre experiencing frequent, severe outbreaks

    If youre sexually active, its a good idea to have regular STI screenings. You can book appointments for STI screenings with your doctors office. You could also try a local clinic, certain pharmacies, or Planned Parenthood.

    What Prescription Drugs Treat Cold Sores

    Prescription-strength topical medications: Treatment with topical acyclovir or penciclovir will reduce healing time by approximately half a day and decrease pain associated with the lesion. Topical treatment is limited in its effectiveness because it has poor penetration to the site of replication of the virus and therefore is restricted in its healing ability. Acyclovir cream should be applied five times per day for 4 days, and penciclovir cream should be applied every two hours while awake for 4 days. A cream containing 5% acyclovir and a topical steroid called Xerese is also available.

    Treatment for the first outbreak of oral herpes in an otherwise healthy person may include:

    • Acyclovir, 400 mg orally three times a day for 10 days or until the lesions have crusted
    • Valacyclovir, 2,000 mg orally every 12 hours for 1 day
    • Famciclovir, 250 mg orally three times a day for 7-10 days
    • Treatment doses for recurrent oral herpes are as follows:
    • Acyclovir, 400 mg orally three times a day for 5 days: It may also be given as 800 mg orally twice a day for 5 days or 800 mg three times a day for 2 days.
    • Valacyclovir, 2,000 mg orally every 12 hours for 1 day
    • Famciclovir, 1,500 mg orally once
    • Suppressive treatment for those with frequent outbreaks may be given for 12 months, but it may be extended if needed:
    • Acyclovir, 400 mg orally twice a day
    • Valacyclovir, 500 mg orally once a day
    • Famciclovir, 250 mg orally twice a day

Take or use acyclovir at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
