ZORVIRAX
Zovirax is a prescription cream medication that is effective in the initial phases of genital herpes and in the treatment of mouth ulcers and lip blisters caused by the herpes simplex virus.
Brand Name(s): Zovirax
Generic Name Acyclovir
Phonetic: (ay sye' kloe veer)
Who is this for?
Acyclovir is used to treat herpes infections of the skin, lip, and genitals;
herpes zoster (shingles); and chickenpox. It does not cure herpes infections but
decreases pain and itching and promotes healing. Topical acyclovir does not
prevent the recurrence of sores but may decrease pain and itching if applied
when the earliest symptoms first appear. Oral acyclovir decreases the frequency
and severity of recurrent sores, but it is used only by people with severe
herpes infections because of possible adverse effects. This medication is
sometimes prescribed for other uses; ask your doctor or pharmacist for more
information.
When should I be careful taking it?
Before taking acyclovir,
tell your doctor and pharmacist if you are allergic to acyclovir or any other
drugs.
tell your doctor and pharmacist what prescription and nonprescription
medications you are taking, especially probenecid (Benemid), zidovudine (Retrovir,
AZT), and vitamins.
tell your doctor if you have or have ever had kidney disease, problems with your
immune system, human immunodeficiency virus infection (HIV), or acquired
immunodeficiency syndrome (AIDS).
tell your doctor if you are pregnant, plan to become pregnant, or are
breast-feeding. If you become pregnant while taking acyclovir, call your doctor.
What side effects should I watch for?
Although side effects from acyclovir are not common, they can occur. Tell your
doctor if any of these symptoms are severe or do not go away:
burning, stinging, itching, or rash when ointment is applied
headache
upset stomach
vomiting
diarrhea or loose stools
If you experience any of the following symptoms, call your doctor immediately:
severe rash
severe itching
How should I take it?
Acyclovir comes as an ointment for use on the skin and as a tablet, capsule, and
liquid to take by mouth. Follow the directions on your prescription label
carefully, and ask your doctor or pharmacist to explain any part you do not
understand. Take acyclovir exactly as directed. Do not take more or less of it
or take it more often than prescribed by your doctor. Use this medication as
soon as possible after symptoms appear. Clean and dry the skin area before
applying the ointment. Wear protective gloves when applying it to prevent the
spread of infection. Rub the ointment in gently. Use enough ointment to cover
all sores completely. Do not apply acyclovir ointment to the eyes. Shake the
liquid well before each use to mix the medication evenly. Continue to take
acyclovir even if you feel well. Do not stop taking acyclovir without talking to
your doctor.
Dietary Considerations
Acyclovir may cause an upset stomach. Take acyclovir with food or milk.
What happens if I miss a dose?
If you are using tablets, capsules, or liquid, take the missed dose as soon as
you remember it and take any remaining doses for that day at evenly spaced
intervals. If you are using ointment, apply it as soon as you remember and apply
further doses at your regular interval (e.g., every 3 hours) until you go to
bed. However, if it is almost time for the next dose, skip the missed dose and
continue your regular dosing schedule. Do not take a double dose of either the
ointment or oral medication to make up for a missed one.
Where should I keep it?
Keep this medication in the container it came in, tightly closed, and out of
reach of children. Store it at room temperature and away from excess heat and
moisture (not in the bathroom). Throw away any medication that is outdated or no
longer needed. Talk to your pharmacist about the proper disposal of your
medication.
