Antivirals such as acyclovir, famciclovir, or valacyclovir may be used. Intravenous acyclovir is reserved for individuals who cannot swallow due to the pain, individuals with other systemic manifestations of herpes or severely immunocompromised individuals.

Several antiviral drugs are effective for treating herpes, including acyclovir, valaciclovir (valacyclovir), famciclovir, and penciclovir. Acyclovir was the first discovered and is now available in generic. Valacyclovir is also available as a generic and is slightly more effective than aciclovir for reducing lesion healing time.

Evidence supports the use of acyclovir and valacyclovir in the treatment of herpes labialis as well as herpes infections in people with cancer. The evidence to support the use of acyclovir in primary herpetic gingivostomatitis is weaker.

No method eradicates herpes virus from the body, but antiviral medications can reduce the frequency, duration, and severity of outbreaks. Analgesics such as ibuprofen and paracetamol (acetaminophen) can reduce pain and fever. Topical anesthetic treatments such as prilocaine, lidocaine, benzocaine, or tetracaine can also relieve itching and pain.

Herpes outbreaks should be treated with antiviral medications like Acyclovir, Valacyclovir, or Famcyclovir, each of which is available in tablet form.

Oral antiviral medication is often used as a prophylactic to suppress or prevent outbreaks from occurring. The recommended dosage for suppression therapy for recurrent outbreaks is 1,000 mg of valacyclovir once a day or 400 mg Acyclovir taken twice a day. In addition to preventing outbreaks, these medications greatly reduce the chance of infecting someone while the patient is not having an outbreak.

Often, people have regular outbreaks of anywhere from 1 to 10 times per year, but stress (because the virus lies next to the nerve cells), or a weakened immune system due to a temporary or permanent illness can also spark outbreaks. Some people become infected but fail to ever have a single outbreak, although they remain carriers of the virus and can pass the disease on to an uninfected person through asymptomatic shedding (when the virus is active on the skin but rashes or blisters do not appear).

The use of antiviral medications has been shown to be effective in preventing acquisition of the herpes virus. Specific usage of these agents focus on wrestling camps where intense contact between individuals occur on a daily basis over several weeks. They have also been used for large outbreaks during seasonal competition, but further research needs to be performed to verify efficacy.

Antiviral drugs may reduce the severity and duration of shingles; however, they do not prevent postherpetic neuralgia. Of these drugs, aciclovir has been the standard treatment, but the new drugs valaciclovir and famciclovir demonstrate similar or superior efficacy and good safety and tolerability. The drugs are used both for prevention (for example in HIV/AIDS) and as therapy during the acute phase. Complications in immunocompromised individuals with shingles may be reduced with intravenous aciclovir. In people who are at a high risk for repeated attacks of shingles, five daily oral doses of aciclovir are usually effective.

Docosanol, a saturated fatty alcohol, is a safe and effective topical application that has been approved by the United States Food and Drug Administration for herpes labialis in adults with properly functioning immune systems. It is comparable in effectiveness to prescription topical antiviral agents. Due to its mechanism of action, there is little risk of drug resistance. The duration of symptoms can be shortened a bit if an antiviral, anesthetic, zinc oxide or zinc sulfate cream is applied soon after it starts.

Effective antiviral medications include acyclovir and penciclovir, which can speed healing by as much as 10%. Famciclovir or valacyclovir, taken in pill form, can be effective using a single day, high-dose application and is more cost effective and convenient than the traditional treatment of lower doses for 5–7 days.

People with mild to moderate pain can be treated with over-the-counter pain medications. Topical lotions containing calamine can be used on the rash or blisters and may be soothing. Occasionally, severe pain may require an opioid medication, such as morphine. Once the lesions have crusted over, capsaicin cream (Zostrix) can be used. Topical lidocaine and nerve blocks may also reduce pain. Administering gabapentin along with antivirals may offer relief of postherpetic neuralgia.

, genital herpes cannot be cured. There are, however, some medications that can shorten outbreaks including acyclovir, valacyclovir, and famciclovir.

Acyclovir is an antiviral medication and reduces the pain and the number of lesions in the initial case of genital herpes. Furthermore, it decreases the frequency and severity of recurrent infections. It comes in capsules, tablets, suspension, injection, powder for injection, and ointment. The ointment is used topically and it decreases pain, reduces healing time, and limits the spread of the infection.

Valacyclovir once in the body, it is converted to acyclovir. It helps relieve the pain and discomfort and the sores heal faster. It only comes in caplets and its advantage is that it has a longer duration of action than acyclovir. An example usage is by mouth twice per day for 10 days for primary lesion, and twice per day for 3 days for a recurrent episode.

Famciclovir is another antiviral drug that belongs to the same class. Famciclovir is a prodrug that is converted to penciclovir in the body. The latter is the one active against the viruses. It has a longer duration of action than acyclovir and it only comes in tablets.

Key measures to prevent outbreaks of the disease are maintaining hygiene standards and using screening to exclude persons with suspicious infections from engaging in contact sports. A skin check performed before practice or competition takes place can identify individuals who should be evaluated, and if necessary treated by a healthcare professional. In certain situations, i.e. participating in wrestling camps, consider placing participants on valacyclovir 1GM daily for the duration of camp. 10-year study has shown 89.5% reduction in outbreaks and probable prevention of contracting the virus. Medication must be started 5 days before participation to ensure proper concentrations exist.

Although it is a self-limited illness, oral or intravenous antiviral treatments, particularly acyclovir, have been used in the management of immunocompromised or severely infected patients. Topical acyclovir has not been shown to be effective in management of herpetic whitlow. Famciclovir has been demonstrated to effectively treat and prevent recurrent episodes. Lancing or surgically debriding the lesion may make it worse by causing a superinfection or encephalitis.

Treatments of proven efficacy are currently limited mostly to herpes viruses and human immunodeficiency virus. The herpes virus is of two types: herpes type 1 (HSV-1, or oral herpes) and herpes type 2 (HSV-2, or genital herpes). Although there is no particular cure; there are treatments that can relieve the symptoms. Drugs like Famvir, Zovirax, and Valtrex are among the drugs used, but these medications can only decrease pain and shorten the healing time. They can also decrease the total number of outbreaks in the surrounding. Warm baths also may relive the pain of genital herpes.

Human Immunodeficiency Virus Infection (HIV) is treated by using a combination of medications to fight against the HIV infection in the body. This is called antiretroviral therapy (ART). ART is not a cure, but it can control the virus so that a person can live a longer, healthier life and reduce the risk of transmitting HIV to others around him. ART involves taking a combination of HIV medicines (called an HIV regimen) every day, exactly as prescribed by the doctor. These HIV medicines prevent HIV Virus from multiplying (making copies of itself in the body), which reduces the amount of HIV in the body. Having less HIV in the body gives the immune system a chance to recover and fight off infections and cancers. Even though there is still some HIV in the body, the immune system is strong enough to fight off infections and cancers. By reducing the amount of HIV in the body, HIV medicines also reduce the risk of transmitting the virus to others. ART is recommended for all people with HIV, regardless of how long they’ve had the virus or how healthy they are. If left untreated, HIV will attack the immune system and eventually progress to AIDS.

Herpes simplex virus is commonly found in humans, yet uncommonly results in systemic manifestations. Suppression of HIV with antiretroviral medications, careful monitoring of immunosuppressive medications are important means of prevention. Antiviral prophylaxis such as daily acyclovir in immunocompromised individuals may be considered.

Reductions in morbidity and mortality are due to the use of antiviral treatments such as vidarabine and acyclovir. However, morbidity and mortality still remain high due to diagnosis of DIS and CNS herpes coming too late for effective antiviral administration; early diagnosis is difficult in the 20-40% of infected neonates that have no visible lesions. A recent large scale retrospective study found disseminated NHSV patients least likely to get timely treatment, contributing to the high morbidity/mortality in that group.

Harrison's Principles of Internal Medicine, recommends that pregnant women with active genital herpes lesions at the time of labor be delivered by caesarean section. Women whose herpes is not active can be managed with acyclovir. The current practice is to deliver women with primary or first episode non primary infection via caesarean section, and those with recurrent infection vaginally, even in the presence of lesions because of the low risk (1-3%) of vertical transmission associated with recurrent herpes.

Development of new therapies has been hindered by the lack of appropriate animal model systems for some important viruses and also because of the difficulty in conducting human clinical trials for diseases that are rare. Nonetheless, numerous innovative approaches to antiviral therapy are available including candidate thiazolide and purazinecarboxamide derivatives with potential broad-spectrum antiviral efficacy. New herpes virus drugs include viral helicase-primase and terminase inhibitors. A promising new area of research involves therapies based on enhanced understanding of host antiviral immune responses.

The likelihood of the infection being spread can be reduced through behaviors such as avoiding touching an active outbreak site, washing hands frequently while the outbreak is occurring, not sharing items that come in contact with the mouth, and not coming into close contact with others (by avoiding kissing, oral sex, or contact sports).

Because the onset of an infection is difficult to predict, lasts a short period of time and heals rapidly, it is difficult to conduct research on cold sores. Though famciclovir improves lesion healing time, it is not effective in preventing lesions; valaciclovir and a mixture of acyclovir and hydrocortisone are similarly useful in treating outbreaks but may also help prevent them.

Acyclovir and valacyclovir by mouth are effective in preventing recurrent herpes labialis if taken prior to the onset of any symptoms or exposure to any triggers. Evidence does not support L-lysine.

The treatment of TORCH syndrome is mainly supportive and depends on the symptoms present; medication is an option for herpes and cytomegalovirus infections.

Treatment includes fluid intake, good oral hygiene and gentle debridement of the mouth, as well as oral acyclovir. In healthy individuals the lesions heal spontaneously in 7–14 days without scarring.

TORCH syndrome can be prevented by treating an infected pregnant person, thereby preventing the infection from affecting the fetus.

Testing peoples blood, including those who are pregnant, who do not have symptoms for HSV is not recommended. This is due to concerns of greater harm than benefit such as relationship problems in the setting of a high rate of tests that may be falsely positive.

Herpesviral Encephalitis can be treated with high-dose intravenous acyclovir. Without treatment, HSE results in rapid death in approximately 70% of cases; survivors suffer severe neurological damage. When treated, HSE is still fatal in one-third of cases, and causes serious long-term neurological damage in over half of survivors. Twenty percent of treated patients recover with minor damage. Only a small population of survivors (2.5%) regain completely normal brain function. Indeed, many amnesic cases in the scientific literature have etiologies involving HSE. Earlier treatment (within 48 hours of symptom onset) improves the chances of a good recovery. Rarely, treated individuals can have relapse of infection weeks to months later. There is evidence that aberrant inflammation triggered by herpes simplex can result in granulomatous inflammation in the brain, which responds to steroids. While the herpes virus can be spread, encephalitis itself is not infectious. Other viruses can cause similar symptoms of encephalitis, though usually milder (Herpesvirus 6, varicella zoster virus, Epstein-Barr, cytomegalovirus, coxsackievirus, etc.).

Epithelial keratitis is treated with topical antivirals, which are very effective with low incidence of resistance. Treatment of the disease with topical antivirals generally should be continued for 10–14 days. Aciclovir ophthalmic ointment and Trifluridine eye drops have similar effectiveness but are more effective than Idoxuridine and Vidarabine eye drops. Oral acyclovir is as effective as topical antivirals for treating epithelial keratitis, and it has the advantage of no eye surface toxicity. For this reason, oral therapy is preferred by some ophthalmologists.

Ganciclovir and brivudine treatments were found to be equally as effective as acyclovir in a systematic review.

Valacyclovir, a pro-drug of acyclovir likely to be just as effective for ocular disease, can cause thrombotic thrombocytopenic purpura/Hemolytic-uremic syndrome in severely immunocompromised patients such as those with AIDS; thus, it must be used with caution if the immune status is unknown.

Topical corticosteroids are contraindicated in the presence of active herpetic epithelial keratitis; patients with this disease who are using systemic corticosteroids for other indications should be treated aggressively with systemic antiviral therapy.

The effect of interferon with an antiviral agent or an antiviral agent with debridement needs further assessment.

Acyclovir is the treatment of choice for Mollaret's meningitis. Some patients see a drastic difference in how often they get sick and others don't. Often treatment means managing symptoms, such as pain management and strengthening the immune system.

The IHMF recommends that patients with benign recurrent lymphocytic meningitis receive intravenous acyclovir in the amount of 10 mg/kg every 8 hours, for 14–21 days. More recently, the second-generation antiherpetic drugs valacyclovir and famciclovir have been used to successfully treat patients with Mollaret's. Additionally, it has been reported that Indomethacin administered in the amount of 25 mg 3 times per day after meals, or 50 mg every 4 hours, has resulted in a faster recovery for patients, as well as more extended symptom-free intervals, between episodes.

Herpetic stromal keratitis is treated initially with prednisolone drops every 2 hours

accompanied by a prophylactic antiviral drug: either topical antiviral or an oral agent such as acyclovir or valacyclovir. The prednisolone drops are tapered every 1–2 weeks depending on the degree of clinical improvement. Topical antiviral medications are not absorbed by the cornea through an intact epithelium, but orally administered acyclovir penetrates an intact cornea and anterior chamber. In this context, oral acyclovir might benefit the deep corneal inflammation of disciform keratitis.

Recurring Mollaret meningitis attacks will occur through the patient lifespan so long as the HSV virus is not managed. Patients have reported symptoms for as long as 30 years from first episode. Diet and stress management are key to keeping the HSV virus at bay.

It can be treated with systemic antiviral drugs, such as aciclovir or valganciclovir. Foscarnet may also be used for immunocompromised host with Herpes simplex and acyclovir-resistant Herpes simplex.
