Genital Herpes
Treatment Overview
The goal of treatment for genital herpes is to provide relief from the discomfort of herpes sores and to reduce the time it takes for an outbreak to heal.
Treatment works best if it is started as soon as possible after an outbreak begins. This is especially true for outbreaks that come back again and again.
Initial treatment
Most people find some relief and recover more quickly from the first (primary) outbreak of genital herpes by taking antiviral medicines.
- Use medicines to relieve symptoms and speed healing of blisters and sores.
- Antiviral medicines, such as acyclovir (Zovirax), famciclovir (Famvir), or valacyclovir (Valtrex) are recommended for treating primary genital herpes outbreaks.
- Nonprescription medicines, such as ibuprofen (Advil) or acetaminophen (Tylenol), may reduce the pain and fever from genital herpes.
- Use home treatment, such as taking warm sitz baths and wearing cotton underwear, to promote healing of herpes sores. For more information, see the Home Treatment section of this topic.
- Take steps to prevent the spread of genital herpes. These include avoiding any sexual contact if you or your partner have symptoms or are being treated for genital herpes. For more information, see the Prevention section of this topic.
Studies show that antiviral medicine can reduce the time it takes a primary outbreak to heal by 4 days.2 The medicine also decreases the number of days you can spread the virus (are contagious).
Taking antiviral medicine for the primary genital herpes outbreak does not prevent genital herpes outbreaks from recurring.
Ongoing treatment
The decision to take antiviral medicines for recurrent outbreaks of genital herpes depends on how long the outbreaks last, how severe they are, and how often they return. People who do not have frequent or severe outbreaks may not want to take medicine on a regular basis.
Antiviral medicines reduce the time it takes for genital herpes sores to heal and helps prevent some outbreaks. Antiviral medicines have the added benefit of reducing the possibility that people can transmit HSV to their sex partner(s).
People can take antiviral medicine for recurrent outbreaks of genital herpes either:
- Every day. Some people take antiviral medicine every day to help reduce the risk of recurrent outbreaks and reduce how long a recurrent outbreak lasts. Antiviral medicine may reduce the number of outbreaks by about one or two episodes a year.
- As needed. Some people take antiviral medicine when they first notice the prodromal symptoms (tingling and pain) of a recurrent outbreak. Medicines used only for 2 or 3 days must be used at higher doses than when taken every day to be effective. Antiviral medicine can reduce the time it takes for the sores to heal by 2 days.2
A study has shown that an HSV-infected person in a heterosexual, single-partner (monogamous) relationship who takes valacyclovir daily to prevent recurrent outbreaks reduces by about half the risk of infecting his or her partner.3 Other antiviral medicines may also reduce transmission but further study is needed.
Home treatment, such as taking warm sitz baths and wearing cotton underwear, can promote healing of herpes sores. For more information, see the Home Treatment section of this topic.
You can reduce the risk of transmitting HSV to your sex partner(s) by taking steps to prevent the spread of genital herpes. These include avoiding any sexual contact if you or your partner have symptoms or are being treated for genital herpes. Using condoms during outbreaks also reduces the risk of giving HSV to your partner.4 For more information, see the Prevention section of this topic.
Treatment during pregnancy
The Centers for Disease Control and Prevention (CDC) has published guidelines about the use of antiviral medicines for genital herpes during pregnancy.1
- Oral acyclovir (Zovirax) may be given to pregnant women for a primary HSV infection or for severe recurrent outbreaks.
- Oral acyclovir may be given to pregnant women at any time during the pregnancy, including the first trimester.
- Acyclovir may be given intravenously (IV) to pregnant women with severe HSV infection.
- Acyclovir may reduce the frequency of recurrent outbreaks in pregnant women close to delivery, thereby reducing the possibility of needing a cesarean section at the time of delivery.
If a genital herpes blister or sore is present at the time of labor and delivery, a cesarean section is usually done. A cesarean section may be recommended if a woman has tingling or pain (prodromal symptoms), suggesting an impending outbreak. Acyclovir (Zovirax) used in the last 4 weeks of pregnancy may reduce the need for delivery by cesarean section by reducing the risk of a recurrent outbreak at the time of delivery.
