Why is grapefruit juice bad for medicine?

Grapefruit has long been hailed as one of the most nutritious fruits out there, with a laundry list of vitamins and minerals that would make your head spin.

The Trouble with Grapefruit Juice

At first glance, grapefruit juice seems innocent enough – after all, it’s just fruit and water, right? Wrong. Grapefruits contain compounds called furanocoumarins which inhibit certain enzymes responsible for breaking down drugs in our bodies. These enzymes are crucial for drug metabolism because they help to remove drugs from our system after we’ve ingested them.

When these enzymes are inhibited by furanocoumarins found in grapefruits (and other citrus fruits like Seville oranges and limes), medications that would otherwise have been safely metabolized start to accumulate in our body at higher levels than intended. This accumulation can lead to an increased risk of side effects or toxicity.

The impact of consuming grapefruit juice depends on many factors such as how much grapefruit juice was consumed, what type of medication was taken, age and overall health status among several others.
