DENAVIR DRUG INFO
Why is this medication prescribed?
Penciclovir is used on the lips and faces of
adults to treat cold sores caused by herpes simplex virus. Penciclovir
does not cure herpes infections but decreases pain and itching if
applied when the earliest symptoms first appear.
This medication is sometimes prescribed for
other uses; ask your doctor or pharmacist for more information.
How should this medicine be used? Penciclovir
comes as a cream. It is usually used externally every 2 hours while
you are awake for 4 days. Follow the directions on your prescription
label carefully, and ask your doctor or pharmacist or doctor to
explain any part you do not understand. Use penciclovir exactly
as directed. Do not use more or less of it or use it more often
than prescribed by your doctor. Use this medication as soon as possible
after symptoms appear.
Clean and dry the area before applying the cream
to avoid spreading the infection. Rub the cream in gently, using
enough cream to cover all sores completely.
Continue to use penciclovir even if you feel
well. Do not stop using penciclovir without talking to your doctor.
What special precautions should I follow?
Before using penciclovir,
- tell your doctor and pharmacist if you are allergic to penciclovir,
acyclovir (Zovirax), or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription
medications you are taking, including vitamins.
- tell your doctor if you are pregnant, plan to become pregnant,
or are breast-feeding. If you become pregnant while taking penciclovir,
call your doctor.
What should I do if I forget a dose?
Apply the missed dose as soon as you remember
it and apply any remaining doses for that day at evenly spaced intervals.
However, if it is almost time for the next dose, skip the missed
dose and continue your regular dosing schedule. Do not apply a double
dose to make up for a missed one.
What side effects can this medication
cause? Although side effects from penciclovir
are not common, they can occur. Tell your doctor if any of these
symptoms are severe or do not go away:
- headache
- irritation at the site of application
What storage conditions are needed
for this medicine? 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is outdated or no longer needed.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.
What other information should
I know? Keep all appointments with your
doctor. Penciclovir should only be used on the lips and face. Avoid
getting it in your eyes. Keep the infected area clean and dry.
Do not let anyone else use your medication.
Ask your pharmacist any questions you have about refilling your
prescription. If you still have symptoms of infection after you
finish the penciclovir, call your doctor.
