It's okay to take drugs that interact with grapefruit, as long as they are separated by two hours.

Patients often ask how long to avoid grapefruit juice if they take certain drugs.

Some are being told to avoid grapefruit altogether...others are told to separate grapefruit from their drugs by a few hours.

Grapefruit can increase the levels of many drugs...lovastatin, simvastatin, diazepam, some calcium channel blockers, protease inhibitors, etc.
