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 doctors 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 a year or who have severe outbreaks 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.
Valacyclovir (Valtrex) also may be used during pregnancy.4, 5
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. For these
people, other antivirals are available, but they must be given through a vein
(intravenously, or IV) and can have dangerous side effects.
