Drug and food interactions
atenolol food
Applies to: atenolol
You may take atenolol with or without food, but take it the same way every time. Avoid consumption of large amounts of orange juice to prevent any changes in your atenolol levels. Orange juice could decrease the effectiveness of atenolol.

Food can enhance the levels of metoprolol in your body. You should take metoprolol at the same time each day, preferably with or immediately following meals. This will make it easier for your body to absorb the medication. Avoid drinking alcohol, which could increase drowsiness and dizziness while you are taking metoprolol. Metoprolol is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
