Herpes is treated with antiviral medications that shorten outbreaks, reduce symptoms, and lower the risk of spreading the virus to others. There is no cure that eliminates herpes from the body, but the right treatment plan can make outbreaks shorter, less painful, and less frequent. Most people with herpes find that their symptoms become very manageable with medication.
How Antiviral Medications Work
Three oral antiviral drugs form the backbone of herpes treatment: acyclovir, valacyclovir, and famciclovir. All three work by blocking the virus’s ability to copy its own DNA, which stops it from multiplying and spreading to new cells. The virus can only replicate when it’s active, so these drugs are most effective when taken early in an outbreak, ideally at the first sign of tingling, itching, or redness.
Valacyclovir and famciclovir are newer formulations designed to be absorbed more efficiently. Both produce higher levels of active antiviral in the bloodstream than standard acyclovir, which means they can be taken fewer times per day while achieving similar or better results. This makes them more convenient for most people, though all three options are effective.
Treating a First Outbreak
A first herpes outbreak is typically the most severe. Sores tend to be more painful, last longer, and may come with flu-like symptoms such as fever, body aches, and swollen lymph nodes. Because of this, treatment for a first episode lasts longer than for recurrences.
The CDC recommends one of three regimens for an initial outbreak, all taken for 7 to 10 days:
- Acyclovir: 400 mg three times daily
- Famciclovir: 250 mg three times daily
- Valacyclovir: 1,000 mg twice daily
If sores haven’t fully healed after 10 days, treatment can be extended. Starting antivirals as soon as symptoms appear makes a noticeable difference in how quickly the outbreak resolves.
Episodic Treatment for Recurrent Outbreaks
After the first episode, many people experience recurrent outbreaks that are milder and shorter. If your outbreaks happen infrequently, episodic treatment is the usual approach. This means keeping a prescription on hand and starting it at the very first sign of a flare-up, such as tingling, burning, or the sensation that a sore is about to form.
Episodic treatment courses are shorter than initial outbreak regimens, often lasting just one to five days depending on the medication and dose. The key is speed: the sooner you start taking the medication, the more it can limit the outbreak. Some people learn to recognize their personal warning signs well enough to start treatment before sores even appear, which can sometimes prevent a visible outbreak entirely.
Daily Suppressive Therapy
If you experience frequent outbreaks, typically six or more per year, daily suppressive therapy is often a better strategy. This involves taking a lower dose of an antiviral every day, whether or not you have symptoms. Daily therapy reduces outbreak frequency by 70% to 80% for most people, and some stop having noticeable outbreaks altogether.
Suppressive therapy also has an important benefit beyond symptom control: it significantly reduces the amount of virus shed from the skin even when no sores are present. This “asymptomatic shedding” is one of the main ways herpes is transmitted to partners, so daily medication lowers transmission risk as well. Many people choose suppressive therapy specifically for this reason, even if their outbreaks are relatively infrequent.
These medications have strong long-term safety profiles. People have taken daily antivirals for herpes for years without significant side effects. Your doctor may suggest stopping suppressive therapy periodically to reassess whether your outbreak frequency has naturally decreased over time, which it often does.
Topical Treatments and Over-the-Counter Options
Topical antivirals exist for oral herpes (cold sores) but offer considerably less benefit than oral medications. Topical acyclovir cream, penciclovir cream, and docosanol (the active ingredient in Abreva, available without a prescription) all reduce healing time and pain duration by less than a day in clinical trials. They also require multiple applications per day.
By comparison, oral antivirals reduce healing time by roughly one to two days, with some regimens shortening it by more than two days. No head-to-head trials have directly compared oral versus topical treatments, but the difference in effect size is clear from separate studies. For genital herpes, topical treatments are not recommended as a primary approach.
A combination cream containing acyclovir and hydrocortisone (a mild steroid to reduce inflammation) showed a slight advantage over placebo in one trial, shortening healing by about 0.8 days, but it didn’t outperform acyclovir cream alone.
Managing Pain and Discomfort at Home
Alongside antiviral medication, several practical steps can make an active outbreak more bearable. Cool compresses applied to sores several times a day help relieve pain and itching. Loose-fitting cotton underwear reduces irritation, while synthetic fabrics and tight pants can trap moisture and make things worse. Keep sores clean by washing gently with soap and water, then pat dry. Let sores air-dry rather than covering them with bandages, as air exposure speeds healing.
Avoid picking at sores, which can introduce bacteria and slow healing. Don’t apply ointments or lotions to sores unless specifically prescribed. For women experiencing pain while urinating during a genital outbreak, urinating while sitting in a shallow tub of warm water can help dilute the urine and reduce the stinging sensation on open sores. Over-the-counter pain relievers like ibuprofen or acetaminophen can help with general discomfort.
Herpes During Pregnancy
Herpes requires special attention during pregnancy because the virus can be transmitted to a baby during delivery, which can cause serious complications. The greatest risk occurs when a person acquires herpes for the first time late in pregnancy, because the body hasn’t yet developed antibodies that help protect the baby.
For pregnant people with a history of genital herpes, antiviral medication is typically started in the third trimester to suppress outbreaks and reduce the chance of active sores being present at delivery. If an active outbreak is occurring when labor begins, a cesarean delivery is usually recommended to avoid exposing the baby to the virus. If no sores are present, vaginal delivery is generally considered safe.
What Treatment Cannot Do
Antivirals control herpes, but they don’t eliminate it. After an initial infection, the virus retreats into nerve cells near the base of the spine (for genital herpes) or near the ear (for oral herpes), where it remains dormant. Medications cannot reach the virus in this dormant state. Outbreaks occur when the virus periodically reactivates and travels back to the skin surface.
The good news is that for most people, outbreaks become less frequent and less severe over time, even without suppressive therapy. The first year after infection tends to be the most active, and many people find that after several years, outbreaks become rare or stop entirely. Effective antiviral treatment makes the condition very manageable for the vast majority of people living with it.
