The name of your medicine is GRISOVIN.
GRISOVIN contains the antifungal griseofulvin.
GRISOVIN is available in two strengths: Grisovin 125 mg uncoated tablets and Grisovin 500 mg uncoated tablets.
GRISOVIN is used to treat tinea, a fungal infection.
GRISOVIN is only used when other antifungal treatments, such as tinea creams or powders, have not worked.
GRISOVIN will not work for bacterial or viral infections.
Tinea may occur in the skin of the body, scalp, hair or nails. GRISOVIN works by helping newly formed skin, hair and nails to resist attack by fungi. As the new tissue (keratin) grows, the old infected keratin is cast off. That is why it is important to continue treatment until all the old infected tissue is gone.
Ask your doctor (or pharmacist) if you have any questions about why GRISOVIN has been prescribed for you.
GRISOVIN is available only with a doctor’s prescription.
Before taking GRISOVIN, you must tell your doctor:
GRISOVIN may reduce the effectiveness of oral contraceptives. Extra contraceptive precautions (e.g. condom) should be used during GRISOVIN treatment and for a month after stopping GRISOVIN.
GRISOVIN may cause birth defects. It must not be used during pregnancy. If you intend to become pregnant, you should delay pregnancy until one month after stopping GRISOVIN treatment.
GRISOVIN may cause abnormalities in sperm cells. Men should not father children until at least six months after stopping GRISOVIN treatment.
Do not use GRISOVIN if the packaging shows sign of tampering or the seal is broken.
Do not use GRISOVIN after the expiry date printed on the pack has passed.
It may have no effect at all, or worse, it may give an entirely unexpected effect if you use after the expiry date.

Tell your doctor (or pharmacist) if you are taking any other medicines.
This includes any that you buy without a prescription from a pharmacy, supermarket or health food shop.
Some medicines may affect the way other's work. Your doctor or pharmacist can tell you what to do when taking GRISOVIN with other medicines.
The following information lists the usual dose of GRISOVIN.
Adults - The usual dose is 500 mg per day. For nail infections, your doctor may prescribe up to 1000 mg daily until a response is apparent, at which time the dose may be reduced to 500 mg per day.
Children - The usual dose is 10 mg/kg body weight daily, taken in divided doses.
The dose will depend on the type of treatment required for a patient.
Your doctor will decide the number of doses needed each day and how long you will need to take GRISOVIN. These doses may differ from the usual doses shown in this leaflet.
If your dose is different to that described in this leaflet do not change it unless your doctor tells you to.
Follow the instructions given by your doctor and pharmacist and read the label carefully.
If you do not understand the instructions on the box or bottle, ask your doctor or pharmacist.
GRISOVIN tablets should always be taken after meals. They will work better if some fat is included in the meal (for example milk or ice cream). If you are on a fat reduced diet, you should tell your doctor.
Your doctor will advise you how long you will need to take GRISOVIN.
Generally, hair or skin infections need at least 4 weeks treatment. Infection of the toenails or fingernails may need 6 to 12 months treatment. Treatment should be continued for at least 2 weeks after all signs of the infection have disappeared.
If you forget to take GRISOVIN, take it as soon as possible with food.
If it is almost time for your next dose, skip the missed dose, and take the next dose at the usual time.
