What this medicine is used for
The name of your medicine is APO-Famciclovir. It contains the active ingredient, famciclovir.
Famciclovir is an antiviral medicine used to treat shingles in adults and adolescents.
How it works
Shingles is a condition that is caused by a herpes virus called varicella zoster, the same virus that causes chicken pox.
The virus can become active again in the body, even after many years, resulting in shingles. The main symptom is a rash that
can cause pain, burning and blisters.
Although famciclovir does not cure the viral infection, it helps to relieve the symptoms and shorten their duration.
The best results are obtained if the medicine is started as soon as possible after the first symptoms begin to appear.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed famciclovir for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.
Use in children
Famciclovir is not recommended for use in children under 12 years of age.

Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from
your pharmacy, supermarket or health food shop.
Some medicines and famciclovir may interfere with each other. These include:
probenecid, a prescription medicine used to treat gout (a disease with painful, swollen joints caused by uric acid crystals)

weaker, more brittle and likely to break)

to be careful with or avoid while taking famciclovir.
Other interactions not listed above may also occur.
