What is the most important information I should know about griseofulvin (Gris Peg)?

You should not use griseofulvin if you are allergic to it, or if you have liver failure, porphyria, or if you are pregnant.

Before you take griseofulvin, tell your doctor if you have liver disease, heart disease, lupus, or an allergy to penicillin.

Avoid exposure to sunlight or tanning beds. Griseofulvin can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Drinking alcohol can increase certain side effects of griseofulvin.

Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Griseofulvin will not treat a viral infection such as the common cold or flu.
