Be careful not to drink too much grapefruit, orange, or apple juice while on beta blockers. You don’t have to avoid any other foods while taking beta blockers.

Don’t drink more than one glass (300 mL) a day. This is especially true for these beta blockers:

  • Atenolol
  • Carvedilol
  • Labetalol
  • Metoprolol
  • Nebivolol

Eating grapefruits, oranges, or apples can be healthy. Drinking too much of their juice can affect how your medicine works. They can decrease or increase how much medicine gets absorbed by your body. This can make your beta blocker less useful in lowering your blood pressure. It can also be harmful if your body absorbs the medicine too much.

So avoid drinking too much of these juices. Tell your doctor about other drugs you take. This includes vitamins, supplements, or herbal products. Otherwise, you don’t need to avoid other foods while taking beta blockers. 

Give your beta blocker a break and limit juice intake!
