Medicine For Herpes Simplex 1

Episodic Therapy For Recurrences

For a recurrent episode, treatment takes 1 to 5 days, depending on the type of medication and dosage. You should begin the medication as soon as you notice any signs or symptoms of herpes, preferably during the prodrome stage that precedes the outbreak of lesions.

In order for episodic therapy to be effective, it must be taken no later than 1 day after a lesion appears. If taken during prodrome, episodic therapy may help prevent an outbreak from occurring or reduce its severity. If taken at the first sign of a lesion, it can help speed healing.

Additional Treatment For Oral Herpes

Antiviral pills are often a better choice for treating oral herpes, especially if you have recurrent outbreaks . Theyre typically less expensive than oral herpes creams and are effective options to consider.

If you have persistent oral herpes infections, taking oral antiviral medications may be a better option than creams. Here are three of the most commonly used oral antivirals with their typical cold sore treatment doses:

• Valacyclovir : 2,000 mg by mouth every 12 hours for 1 day

• Famciclovir: 1,500 mg by mouth one time only

• Acyclovir buccal tablets : 50 mg dissolved in the cheek one time only. Healthcare providers sometimes prescribe different doses of oral acyclovir capsules and tablets. This is considered an off-label use, as theyre not FDA-approved for treating cold sores.

There are currently no studies that directly compare all three antiviral medications. But a review of multiple studies found that valacyclovir healed cold sores faster than acyclovir.

How Do People Get Genital Herpes

Infections are transmitted through contact with HSV in herpes lesions, mucosal surfaces, genital secretions, or oral secretions. 5 HSV-1 and HSV-2 can be shed from normal-appearing oral or genital mucosa or skin. 7,8 Generally, a person can only get HSV-2 infection during genital contact with someone who has a genital HSV-2 infection. However, receiving oral sex from a person with an oral HSV-1 infection can result in getting a genital HSV-1 infection. 4 Transmission commonly occurs from contact with an infected partner who does not have visible lesions and who may not know that he or she is infected. 7 In persons with asymptomatic HSV-2 infections, genital HSV shedding occurs on 10.2% of days, compared to 20.1% of days among those with symptomatic infections. 8

Binding And Entry Inhibition

Other antiviral drugs act on the host cell to inhibit the virus . The advantage to this approach is that resistance to the drug is less likely to appear, especially because these drugs are not subject to TK activation and ACV resistance mutations in that locus while random mutations occur in both viruses and hosts, the mutation rate in viruses is much higher than it is in host cells . On the other hand, targeting a host cell function may lead to higher toxicity, potentially limiting therapeutic use to only viral strains that are resistant to safer therapies.

‘i Hope That This Study Changes The Dialogue Around Herpes Research And Opens Up The Idea That We Can Start Thinking About Cure Rather Than Just Control Of The Virus’

â Dr. Keith Jerome, Fred Hutchinson Cancer Research Center

Whereas most research on herpes has focused on suppressing the recurrence of painful symptoms, the Fred Hutch gene therapy work addresses the root cause of reactivation: the presence of latent virus in infected nerve cells.

âI hope that this study changes the dialogue around herpes research and opens up the idea that we can start thinking about cure, rather than just control of the virus,â Jerome said.

It will still take a long time before these experiments lead to the first human trials of gene therapy to cure herpes. Jerome estimates that will be at least three years away.

Herpes simplex viruses afflict billions of human beings around the globe. According to the World Health Organization, two-thirds of the world population under the age of 50 carry herpes simplex virus type 1, or HSV-1, which primarily causes cold sores, while 491 million people aged 15-49 are infected with closely related HSV-2, which is the cause of sexually transmitted genital herpes.

Causes Of Herpes Simplex Eye Infections

Herpes simplex eye infections usually occur when a previous infection with the virus reactivates and spreads to the eye.

Nearly everyone is exposed to the herpes simplex virus during childhood. Most people will not notice this because there are often no symptoms. But afterwards the virus will remain inactive in the body.

In some people, the virus can be reactivated later on. This can happen randomly or may be triggered by:

• an illness or a high temperature
• exposure to strong sunlight or cold wind
• having a weakened immune system for example, if you have chemotherapy

What Other Disease/condition Shares Some Of These Symptoms

Infection with coxsackie virus causes a syndrome called herpangina, which is similar to orolabial herpes simplex. Herpangina involves vesicles in the posterior aspect of the mouth, including the throat and soft palate. In addition, a mild case of orolabial herpes can resemble secondary bacterial infection, so that the physician can make an erroneous diagnosis of impetigo. Viral meningoencephalitis of many different pathogens can have features similar to the CNS form of HSV-1 disease.

How Do You Get Cold Sores

You can transmit and become infected by the HSV-1 virus by touching others, especially through kissing, as the virus is passed on through saliva and direct contact with the lips. You can also contract the virus by sharing infected items such as eating utensils or by sharing cosmetics.vRemember that someone may be infected without showing symptoms.

Symptoms Of Oral Herpes

Oral herpes is most often caused by HSV-1, but can also be caused by HSV-2. It usually affects the lips and, in some primary attacks, the mucous membranes in the mouth. A herpes infection may occur on the cheeks or in the nose, but facial herpes is very uncommon.

Primary Oral Herpes Infection

If the primary oral infection causes symptoms, they can be very painful, particularly in children. Symptoms include:

• Tingling, burning, or itching around the mouth are the first signs.
• Red, fluid-filled blisters that may form on the lips, gums, mouth, and throat.
• Blisters that break open and leak. As they heal, they turn yellow and crusty, eventually turning into pink skin. The sores last 10 to 14 days and can be very uncomfortable.
• Blisters that may be preceded or accompanied by sore throat, fever, swollen glands, and painful swallowing.

Recurrent Oral Herpes Infection

A recurrent oral herpes infection is much milder than the primary outbreak. It usually manifests as a single sore, commonly called a cold sore or fever blister . The sore usually shows up on the outer edge of the lips and rarely affects the gums or throat.

Are Cold Sores Contagious

Yes, cold sores are extremely contagious. You can become infected with the virus through kissing, touching your fingers to your mouth or eyes , and by sharing infected items. Although the virus doesnt pass through the air, it has been shown to survive on hard surfaces.

Make sure you follow good hand-washing practices, washing with soap for at least 20 seconds and using hand sanitizer when needed. Avoiding close contact with those who have visible signs of the virus and not touching your mouth, eyes and nose are all ways you can help protect yourself against contracting the virus and passing it on to othersvi.

How To Get Rid Of Herpes Naturally

Not every person with a herpes infection actually experiences breakouts of cold sores throughout his or her lifetime or even after initially becoming infected. How often someone has a herpes cold sore outbreak, how severe the outbreaks are, how contagious someone is after infection and how long the sores take to heal all depend on someones individual immune response.

1. Boost Nutrient Intake

If youre going to keep the herpes virus from frequently causing outbreaks, the first step in how to get rid of herpes is to improve immune function by boosting nutrient intake. Include these healing foods in your diet to keep the virus dormant as much as possible:

2. Avoid Inflammatory Foods

Certain foods can raise inflammation, weaken immune defenses and make skin irritation even worse. Avoid the following foods as much as possible to limit outbreak severity and duration.

3. Consider Supplements

• Antiviral herbs: These include elderberry, calendula, echinacea, garlic, astragalus and licorice root.
• L-lysine : Can help treat and prevent outbreaks.
• Lemon balm extract: Apply as a topical cream for healing.
• Vitamin C : Vitamin C boosts immune function improving herpes.
• Zinc : Zinc benefits include supporting immune function, keeping viruses dormant and rebuilding skin tissue to speed up healing.
• B-complex : B vitamins help your body deal with stress and can prevent outbreaks.

4. Try Essential Oils

Complementary And Alternative Medicine

Some people use natural therapies to treat herpes, either on their own or to support standard medical care. The research supporting their use is generally weak, with little evidence that they can reduce either the severity or duration of an outbreak. Even so, many people swear by their effectiveness and consider them a vital part of managing herpes outbreaks.

Complementary and alternative therapies sometimes used to treat herpes include:

• Propolis: This is a sticky substance produced by bees that may help speed the healing of genital herpes. A 2017 study found that people who used propolis ointment experienced better healing by the 10th day of treatment compared to those who used a sham ointment.
• Algae extract: Lab studies suggest that algae extract can inhibit the growth of HSV-2 in test tubes. Whether it can do so in humans has yet to be proven.
• Acupuncture: A 2011 study concluded that acupuncture was mildly effective in reducing pain caused by the herpes zoster virus , the type of herpes virus that causes shingles. While this suggests that acupuncture may be useful in easing genital herpes pain, this has yet to be proven.

Suppressive Therapy For Recurrent Hsv

Suppressive therapy reduces frequency of genital herpes recurrences by 70%80% among patients who have frequent recurrences . Persons receiving such therapy often report having experienced no symptomatic outbreaks. Suppressive therapy also is effective for patients with less frequent recurrences. Long-term safety and efficacy have been documented among patients receiving daily acyclovir, valacyclovir, and famciclovir . Quality of life is improved for many patients with frequent recurrences who receive suppressive therapy rather than episodic treatment . Providers should discuss with patients on an annual basis whether they want to continue suppressive therapy because frequency of genital HSV-2 recurrence diminishes over time for many persons. However, neither treatment discontinuation nor laboratory monitoring is necessary because adverse events and development of HSV antiviral resistance related to long-term antiviral use are uncommon.

Valacyclovir 500 mg orally 2 times/day for 3 daysOR

Valacyclovir 1 gm orally once daily for 5 days

*Acyclovir 400 mg orally 3 times/day is also effective, but are not recommended because of frequency of dosing.

How Is Herpes Simplex Diagnosed

Healthcare providers may diagnose herpes simplex based on how the sores look. Your provider may take a sample from the sore. Laboratory analysis of the sample can confirm or rule out the herpes virus.

If you dont have sores, your healthcare provider can use a blood test to check for HSV-1 and HSV-2 antibody, a marker showing youve been exposed to the virus. The blood test doesnt show an active infection . But it informs your provider whether youve been exposed to the herpes virus in the past. If this is your first infection, you may not test positive for herpes if there hasnt been enough time for your body to develop antibodies. The HSV-1and HSV-2 antibody test may be repeated in eight to 12 weeks.

What You Need To Know

• Fifty percent to 80 percent of U.S. adults have oral herpes.
• Oral herpes can be spread through intimate contact with someone who is infected.
• Oral herpes can be difficult to diagnose. Often confused with many other infections, it can only be confirmed with a virus culture called PCR, blood test or biopsy. PCR is the preferred test for diagnosing herpes infections.
• The best treatment for oral herpes is antiviral oral medication. Symptomatic treatment may include antiviral ointment, over-the-counter topical anesthetics or over-the-counter anti-inflammatory agents.

Whether you call it a cold sore or a fever blister, oral herpes is a common infection of the mouth area that is caused by herpes simplex virus type 1 . Fifty percent to 80 percent of U.S. adults have oral herpes. According to the National Institutes of Health, about 90 percent of adults have been exposed to the virus by age 50.

Once infected, a person will have herpes simplex virus for the rest of his or her life. When inactive, the virus lies dormant in a group of nerve cells. While some people never develop any symptoms from the virus, others will have periodic outbreaks of infections.

Herpes Encephalitis And Meningitis

Herpes Encephalitis

Herpes simplex encephalitis is inflammation of the brain caused by either HSV-1 or HSV-2. It is a rare but extremely serious brain disease. Untreated, herpes encephalitis is fatal most of the time. Respiratory arrest can occur within the first 24 to 72 hours. Fortunately, rapid diagnostic tests and treatment with acyclovir have significantly improved survival rates and reduced complication rates. Nearly all who recover have some impairment, ranging from very mild neurological changes to paralysis.

Herpes Meningitis

Herpes simplex meningitis is inflammation of the membranes that line the brain and spinal cord. It is mainly caused by HSV-2. Like encephalitis, meningitis symptoms include headache, fever, stiff neck, vomiting, and sensitivity to light. Fortunately, herpes meningitis usually resolves after about a week without complications, although symptoms can recur.

What Is The Treatment For Herpes Simplex

Mild, uncomplicated eruptions of herpes simplex require no treatment. Blisters may be covered if desired, for example with a hydrocolloid patch. Severe infection may require treatment with an antiviral agent.

Antiviral drugs used for herpes simplex and their usual doses are:

• Aciclovir 200 mg 5 times daily for five days
• Valaciclovir 500 mg twice daily for five days
• Famciclovir as a single dose of 3 x 500 mg

In New Zealand, famciclovir is not currently funded by PHARMAC .

Higher doses and/or longer courses of antiviral drugs may be used for immunocompromised patients, eczema herpeticum, or for disseminated herpes simplex.

Topical aciclovir or penciclovir may shorten attacks of recurrent herpes simplex, provided the cream is started early enough.

Eastern And South East Asia

HSV-1 seroprevalence in some Asian countries is low, relative to other countries worldwide, with only 51% women in Thailand, and between 50 and 60% in Japan possessing antibodies. HSV-2 seroprevalence in developing Asian countries is comparable to that observed in North America and Northern Europe. However, estimates of HSV-2 infectivity in Thailand are higher than observed in other Eastern Asian countries total HSV-2 seroprevalence is approximately 37% in this country. HSV-2 seroprevalence is low in women in the Philippines , although commencing activity while young is associated with an increase risk of acquiring HSV-2 infection woman starting sexual activity by the time they reach 17 are seven times more likely to be HSV-2 seropositive than those starting sexual activity when over 21.

In South Korea, incidence of HSV-2 infection in those under the age of 20 is low, only 2.7% in men and 3.0% in women. Seroprevalence levels increase in older South Koreans however, such that the population over 20 that has antibodies against HSV-2 is 21.7% of men and 28% of women.
