The most effective treatment for herpes is a prescription antiviral medication, taken either during outbreaks or daily to prevent them. Three oral antivirals are the standard of care: acyclovir, valacyclovir, and famciclovir. All three work by blocking the virus from replicating, which shortens outbreaks and reduces how often they come back. Beyond prescriptions, certain supplements and over-the-counter options can help with symptoms and may lower recurrence rates.
Prescription Antivirals
Acyclovir, valacyclovir, and famciclovir all target the same step in the virus’s life cycle, stopping it from copying its DNA inside your cells. They don’t cure herpes, but they significantly reduce how severe and how long an outbreak lasts. Valacyclovir is the most commonly prescribed because it requires fewer daily doses than acyclovir, making it easier to stick with. Famciclovir works similarly and is a good alternative if you don’t tolerate the others well.
These medications are used in two main ways: episodic therapy and suppressive therapy. The approach your provider recommends depends on how often you get outbreaks and whether reducing transmission to a partner is a priority.
Episodic vs. Suppressive Therapy
Episodic therapy means taking an antiviral only when you feel an outbreak starting. The key is timing. You start the medication at the first sign of symptoms, often a tingling or burning sensation before sores appear. Starting early can shorten an outbreak by several days or even prevent sores from fully developing.
Suppressive therapy means taking a low dose of an antiviral every day, whether or not you have symptoms. This approach cuts outbreak frequency by 70% to 80% in people who get frequent recurrences. It also reduces viral shedding, the periods when the virus is active on the skin surface even without visible sores. Daily valacyclovir at 500 mg has been shown to decrease the rate of HSV-2 transmission in couples where one partner has genital herpes and the other does not.
Suppressive therapy is typically recommended if you experience six or more outbreaks per year, though many people with fewer outbreaks choose it for the transmission benefit or simply for peace of mind. You can stop and reassess at any point, since the medication doesn’t lose effectiveness over time.
Over-the-Counter Topicals
For oral herpes (cold sores), docosanol is the main OTC topical treatment. It’s sold as a cream and works best when applied at the very first sign of a cold sore, before blisters appear. The standard application is five times a day, rubbed gently into the affected area until the sore heals. It won’t cure the infection, but it can reduce pain and speed healing by a day or two. One important limitation: docosanol is designed for use around the mouth only, not on the genitals or near the eyes.
Topical pain relievers containing numbing agents can also help manage the discomfort of active sores. These are applied directly to the affected area and provide temporary relief from burning and itching.
L-Lysine Supplements
L-lysine is the most studied supplement for herpes prevention. It’s an amino acid found in foods like meat, fish, eggs, and dairy. In a six-month double-blind trial, people taking lysine supplements averaged 2.4 times fewer outbreaks than those on a placebo, with milder symptoms and shorter healing times.
Dose matters significantly. A review of the research found that taking less than 1 gram per day was ineffective for both prevention and treatment. Doses above 3 grams per day showed the most benefit, improving patients’ overall experience with the disease. Most people who use lysine for herpes take between 1 and 3 grams daily for maintenance and increase toward the higher end during an active outbreak. Lysine is widely available and inexpensive, and side effects are uncommon at these doses.
Zinc for Herpes Sores
Zinc has shown modest benefits in small studies. In one trial, applying a zinc oxide and glycine cream to herpes sores over 21 days helped reduce symptoms and shorten outbreak duration. A separate study found that taking oral zinc supplements (22.5 mg of zinc sulfate) twice daily for four months reduced the number of herpes episodes over a one-year period. These studies are small, so the evidence is less robust than for antivirals, but zinc carries minimal risk and may be worth trying as an add-on.
Honey and Other Topical Remedies
Medical-grade Manuka honey has limited but promising human data. Applied directly to sores at the start of an outbreak, it appears to reduce pain and itching. Manuka honey has natural antiviral and wound-healing properties, and medical-grade versions are available at most pharmacies. It’s not a replacement for antiviral medication, but some people find it helps with comfort during healing.
Propolis, a compound made by bees, has also been studied alongside lysine. Researchers have suggested that combining propolis with 3 to 5 grams of daily lysine could be beneficial against recurrent outbreaks, though the evidence is still early.
Home Care During an Outbreak
What you do between doses of medication matters too. Warm sitz baths (sitting in a few inches of warm water) help reduce pain and itching from genital herpes sores. Between baths, keep the sores clean and dry. Air-drying tends to feel better than toweling off. Wearing cotton underwear helps absorb moisture and reduces irritation. Loose-fitting clothing in general makes a noticeable difference in comfort during an active outbreak.
Avoid touching the sores and wash your hands if you do. This prevents spreading the virus to other parts of your body, particularly your eyes, and reduces the chance of bacterial infection in open sores.
Putting Together a Treatment Plan
For most people, the most effective approach combines a prescription antiviral with practical self-care. If you get occasional outbreaks, episodic therapy with an antiviral taken at the first sign of symptoms is often enough. If outbreaks are frequent or you want to protect a partner, daily suppressive therapy is the strongest option available. Adding lysine at 1 to 3 grams per day is a reasonable supplement with clinical support behind it, and topical options like docosanol or medical-grade honey can provide additional symptom relief during active sores.
All three prescription antivirals require a healthcare visit to obtain, but many telemedicine services now prescribe them after a brief consultation. The medications are available as generics and are generally affordable even without insurance.
