Can I take Biprosolol and Xanax together?

Drug interaction guide

Taking bisoprolol and Xanax (alprazolam) together can cause an 'additive effect'. This means both drugs work in ways that slow down your body's systems, which can lead to increased drowsiness, dizziness, or a feeling of being very tired. You may also notice your heart rate or blood pressure dropping lower than usual, which can make you feel lightheaded or faint, especially when standing up quickly.

Why this happens

Bisoprolol is a beta-blocker that slows the heart rate and lowers blood pressure. Xanax is a benzodiazepine that slows down brain activity to reduce anxiety. When used together, their combined effects on the central nervous system and the cardiovascular system can be stronger than when taken alone.

You can usually take these medicines together, but you should be cautious. Monitor how you feel, especially when you first start taking them or when your dose is changed. Avoid driving or operating heavy machinery until you know how this combination affects you. If you feel excessively sleepy, dizzy, or faint, contact your doctor. It is also a good idea to avoid alcohol, as it will make these side effects much worse.
