What is Aciclovir cream and what is it used for?

Aciclovir cream is used in the treatment of genital herpes and cold sores. Once genital herpes or a cold sore has appeared,
treatment with Aciclovir cream can accelerate the healing process.
The active substance in Aciclovir cream is aciclovir. Aciclovir is an antiviral agent that has been shown to be effective in
treating infections caused by the herpes simplex virus, such as genital herpes and cold sores.

How to use Aciclovir cream

It is important to start treatment as soon as possible. Always use Aciclovir cream exactly as your doctor has told you. You
should check with your doctor or pharmacist if you are unsure how to use this medicine.
Adults and the elderly:
• Wash your hands before and after applying the cream. This will prevent your
cold sore or genital herpes from getting worse or spreading, or you infecting someone else.
• Apply the cream to the affected area 5 times daily (about every four hours)

for 5 days.
If your cold sore or genital herpes has not healed after five days of treatment you can continue
using the cream for another five days.

If you forget to use Aciclovir cream:
If you forget to apply the cream, apply it as soon as you remember and then apply the next treatment at the usual time.
If you accidentally swallow Aciclovir cream:
Aciclovir cream is for use on cold sores on the lips and surrounding skin and herpes on the genitals only. You are very
unlikely to suffer any bad effects if you accidentally swallow Aciclovir cream. However, if you notice any unusual effects or
are worried tell your doctor or contact the Accident and Emergency Department of your nearest hospital.
