Genital herpes is treated with antiviral medications that shorten outbreaks, reduce their severity, and lower the risk of passing the virus to a partner. There is no cure that eliminates the virus from your body, but treatment can make a significant difference in how often you have symptoms and how much the condition affects your daily life. The approach depends on whether you’re dealing with your first outbreak, occasional recurrences, or frequent flare-ups.
Treatment for a First Outbreak
A first episode of genital herpes is typically the most painful and longest-lasting. Antiviral treatment during this initial outbreak helps sores heal faster and reduces the duration of symptoms like pain, itching, and burning. The CDC recommends a 7 to 10 day course of oral antiviral medication, and treatment can be extended if sores haven’t fully healed by day 10.
Three antiviral drugs are used: acyclovir, valacyclovir, and famciclovir. All three work well. The main practical difference is how often you take them. Valacyclovir is taken twice a day, while acyclovir and famciclovir are taken three times a day. Your provider will typically choose based on cost, insurance coverage, and convenience.
Starting treatment as early as possible matters. The sooner you begin antivirals after symptoms appear, the more effectively they limit viral activity. If you notice tingling, burning, or the first signs of sores, contact a healthcare provider right away rather than waiting to see if a full outbreak develops.
How Antiviral Medications Work
These drugs belong to a class called nucleoside analogs. In plain terms, they trick the virus during its replication process. When herpes tries to copy its DNA to make new viral particles, the medication slips into the process and blocks the copying machinery from completing its work. This stops the virus from multiplying, which is why sores heal faster and viral shedding (the period when you can transmit the virus) is shorter.
Antivirals don’t kill the virus or remove it from your body. Herpes establishes a permanent home in nerve cells near the base of the spine, where it stays dormant between outbreaks. The medications only work when the virus is actively replicating, which is why you take them during outbreaks or daily to keep the virus suppressed.
Episodic Therapy for Recurrent Outbreaks
After your first episode, future outbreaks are usually shorter and less severe. If you get occasional recurrences, you can use what’s called episodic therapy: keeping a prescription on hand and starting it at the very first sign of an outbreak. This approach works best when you begin the medication within 24 hours of noticing prodromal symptoms, the tingling or burning sensation that often precedes visible sores.
Recurrent episodes treated this way typically last a few days shorter than they would without medication. For people who only get one or two outbreaks a year, episodic therapy is often the most practical choice since it avoids the commitment and cost of taking a pill every day.
Daily Suppressive Therapy
If you experience frequent outbreaks, typically six or more per year, daily suppressive therapy is the standard recommendation. This means taking a low dose of an antiviral every day whether or not you have symptoms. Suppressive therapy can reduce the number of outbreaks by 70% to 80% in most people, and many experience no outbreaks at all while on it.
Beyond reducing your own symptoms, daily therapy also lowers the amount of virus you shed asymptomatically. This is significant because herpes can be transmitted even when no sores are visible. For people in relationships with an uninfected partner, daily suppressive therapy (combined with condom use) meaningfully reduces the chance of passing the virus along.
There’s no strict time limit on how long you can take suppressive therapy. Some people stay on it for years. The medications have a strong safety record with long-term use, and your provider may suggest stopping periodically to reassess whether your outbreak frequency has naturally decreased over time, which it often does.
What to Expect During an Outbreak
With treatment, a first outbreak that might last two to four weeks on its own can resolve more quickly, and the pain tends to be less intense. Recurrent outbreaks are generally milder regardless of treatment, often lasting less than a week. Beyond antiviral pills, simple comfort measures help: keeping the area clean and dry, wearing loose cotton underwear, and using a cool compress to ease pain.
Over-the-counter pain relievers can help manage discomfort during an active episode. Warm (not hot) baths may also soothe irritated skin. Avoid touching sores and wash your hands thoroughly if you do, since the virus can be transferred to other body parts, particularly the eyes.
Treatment During Pregnancy
Genital herpes requires special attention during pregnancy because the virus can be transmitted to a newborn during vaginal delivery, potentially causing serious complications. If you have a history of genital herpes, your provider will likely recommend starting daily suppressive antiviral therapy around 36 weeks of pregnancy to reduce the chance of an active outbreak at the time of delivery.
The stakes are highest when a person contracts herpes for the first time during the third trimester, because there hasn’t been enough time for the immune system to build protective antibodies that would also help protect the baby. In these cases, the American College of Obstetricians and Gynecologists notes that cesarean delivery may be offered due to the risk of prolonged viral shedding. A cesarean is also typically recommended if active sores are present when labor begins, regardless of when the infection was first acquired.
Do Supplements Like Lysine Help?
Lysine, an amino acid available as an over-the-counter supplement, is one of the most commonly discussed natural approaches to herpes management. The theory is that lysine competes with another amino acid called arginine, which the herpes virus needs to replicate. The clinical evidence, however, is mixed at best.
A review of the available trials found that doses under 1 gram per day are essentially ineffective. At higher doses (around 1,250 mg per day), some studies showed a modest reduction in outbreak frequency, but others found no significant benefit. Two randomized controlled trials showed no meaningful effect on healing time for active sores. Doses above 3 grams per day appeared to improve how patients felt subjectively, but this hasn’t been confirmed in rigorous trials. The studies that did show positive results often combined lysine with a low-arginine diet (meaning less chocolate, nuts, and seeds), making it hard to isolate the supplement’s effect.
Lysine is generally safe, but it shouldn’t replace antiviral therapy if you’re having frequent or severe outbreaks. Some people use it as a complement to prescription treatment, but the evidence supporting it is far weaker than the evidence for antivirals.
Drug-Resistant Herpes
In rare cases, the herpes virus can develop resistance to standard antiviral medications. This occurs almost exclusively in people with weakened immune systems, such as those undergoing chemotherapy or living with advanced HIV. When resistance develops, alternative medications that target different parts of the virus’s replication process can be used. These alternatives tend to have more side effects and are typically administered in a clinical setting rather than at home.
Living With Herpes Long Term
For most people, the hardest part of a genital herpes diagnosis is the emotional impact rather than the physical symptoms. Outbreaks tend to become less frequent and less severe over time, sometimes tapering to the point where they barely register. The first year after diagnosis is usually the most active in terms of recurrences.
Effective treatment means that genital herpes, while lifelong, doesn’t have to be a constant presence. Many people on suppressive therapy go months or years without an outbreak. The combination of daily antivirals and condoms significantly reduces (though doesn’t eliminate) transmission risk, which makes it possible to have healthy sexual relationships with open communication and a management plan in place.
