Frequently asked questions

Can propranolol help with anxiety?

It can ease physical symptoms like a racing heart and shaking, but it does not treat the worry itself. Use it only as your doctor advises.

Why can't people with asthma take propranolol?

It blocks receptors in the lungs as well as the heart, which can tighten the airways and cause a serious asthma attack.

Is propranolol dangerous in overdose?

Yes — taking too much can be life-threatening. Keep it safely stored and seek emergency help if extra tablets are taken.
