Medications
Antiviral medicines are the recommended treatment for
herpes simplex virus (HSV) infection.
Medication Choices
- Acyclovir (Zovirax), famciclovir (Famvir), and
valacyclovir (Valtrex)
The topical form of acyclovir (Zovirax ointment) offers little
benefit in the treatment of genital herpes and is not recommended.
What To Think About
People taking antiviral medicine every day (suppressive therapy)
may want to talk to their doctor about not taking the medicine for a short
period each year. This can help determine whether genital herpes outbreaks
recur as frequently. They can then decide whether they need to continue taking
medicine. People who have six or more outbreaks per year may benefit from
taking antiviral medicine every day.
Antiviral medicines for genital herpes work best when they are
taken as soon as symptoms are noticed. For that reason, people with herpes
should keep a supply of the medicine on hand.
Acyclovir (Zovirax) is most commonly used for pregnant women.

People with
impaired immune systems may be more likely to:
- Need daily antiviral medicine to prevent
recurrent outbreaks.
- Develop a
resistance to some antiviral medicines. Other
antivirals are available in these cases, although they must be given through a
vein (intravenously, or IV) and can have dangerous side effects.
