Griseofulvin is an antifungal drug used to treat ringworm infections of the skin, hair, and nails caused by specific fungi.
Food, especially with high fat content, increases griseofulvin absorption.1 It is recommended to take griseofulvin with food to maximize absorption of the drug. People on low-fat diets who are taking griseofulvin should talk with their doctor or pharmacist.
Adding 50 IU of vitamin E per day was reported to increase blood levels of this drug within four weeks in children, allowing the drug dose to be cut in half. Reducing the amount of griseofulvin should decrease the likelihood of side effects. This evidence is preliminary, so people taking griseofulvin should not supplement vitamin E on their own but may wish to discuss this matter with their doctor.3
