Does grapefruit affect my medicine?

Eating grapefruit or drinking grapefruit juice can affect some medicines. In most cases, it increases the level of the medicine in your blood. This can increase the risk of side effects or alter the effect that the medicine has.

If your usual diet includes grapefruit or grapefruit juice and you've been prescribed a medicine that's affected by grapefruit, speak to your GP or pharmacist. Do not stop taking your medication without advice.

  • Tegretol and grapefruit and its juice aren't good to mix. It can act as an over dose.
