If you take any of these drugs, you should completely avoid grapefruit
products, tangelos and Seville oranges, unless otherwise directed by
your doctor. Waiting to take these medications — even up to 24 hours —
after you drink grapefruit juice will not prevent an interaction.

Grapefruit also raises post-coffee caffeine levels in the bloodstream,
so is something to be careful (or reckless) with!!
