Drinking alcohol while you're taking beta-blockers generally isn't recommended by doctors.
Beta-blockers lower your blood pressure by slowing your heart rate and reducing the force of each beat. Alcohol can also lower your blood pressure.
When you combine the two, there's a risk that the additive effect on your blood pressure can make your blood pressure fall to a dangerously low level, a condition called hypotension.
If you drink alcohol while taking a beta-blocker and your blood pressure drops too much, you may experience the following symptoms:
Beta-blockers work by blocking the effects of epinephrine. This causes your heart to beat more slowly and pump with less force. The result is that your heart doesn't have to work as hard and is more efficient, which lowers your blood pressure.
Beta-blockers also relax your blood vessels through vasodilation. Pumping blood more efficiently into relaxed blood vessels helps your heart work better if it's damaged or affected by other conditions.
For this reason, in addition to high blood pressure, beta-blockers are commonly used to treat heart problems including:
Beta-blockers are also used to treat other conditions, including:
Alcohol can also have negative effects on the conditions you're treating with beta-blockers, including:
In moderation, alcohol may have a positive effect on some conditions. It may reduce your risk for Graves' disease, the most common type of hyperthyroidism. It may also protect you from some types of heart disease.
Beta-blockers have also been used to help reduce the symptoms of alcohol withdrawal.
commonly prescribed beta-blockers
- acebutolol (Sectral)

- metoprolol (Lopressor, Toprol XL)
- nadolol (Corgard)
- propranolol (Inderal)
If you take other blood pressure medication in addition to beta-blockers, your risk of developing very low blood pressure is increased.
This is especially true for the two classes of medications that lower your blood pressure primarily by dilating your arteries.
Alpha-blockers cause vasodilation in small blood vessels by blocking the effects of norepinephrine. They're also used to treat the symptoms of benign prostatic hypertrophy. Examples include:
Calcium channel blockers cause vasodilation by blocking calcium from entering cells in your blood vessels. Examples include:
When it's an emergencyCall 911 or seek medical care immediately if any of the following happen when you drink alcohol while taking a beta-blocker:
- you faint and think you may have injured yourself
- you faint and hit your head
- you're so dizzy you can't stand up
- you develop a very fast heart rate
If you drink while taking a beta-blocker and develop any of the symptoms mentioned in this article, you should see your doctor. You can have your symptoms evaluated and discuss whether drinking is advisable.
Drinking alcohol while you're taking a beta-blocker can cause your blood pressure to fall. A significant drop can cause you to faint and possibly injure yourself.
In addition, alcohol alone can have negative effects on the condition you're taking a beta-blocker for. It's best to avoid alcohol while you're taking a beta-blocker and, if you do drink, speak to your doctor if you notice any problems.
