Frequently Asked Questions

Propranolol ke sabse common side effects kya hain?

The most common side effects are: slow heartbeat (bradycardia), cold hands and feet, fatigue, and sleep disturbances (nightmares). These are usually mild and the body adjusts. If they are disturbing, inform your doctor — dose adjustment or an alternative is possible.

Kya propranolol asthma mein le sakte hain?

Absolutely not — propranolol is CONTRAINDICATED in asthma. It is a non-selective beta-blocker that blocks beta-2 receptors and can cause bronchospasm which is life-threatening. Ask your doctor about cardioselective alternatives (bisoprolol, atenolol) if you have asthma along with a heart condition.

Propranolol diabetics ke liye kya risk hai?

Propranolol masks a key warning sign of hypoglycaemia — tachycardia (rapid heartbeat). Diabetics must carefully monitor blood glucose and also watch for sweating or confusion.

Propranolol achanak band karne se kya ho sakta hai?

Abrupt withdrawal can cause rebound hypertension (BP suddenly high), unstable angina, and myocardial infarction. This is especially dangerous in angina patients. NEVER stop it on your own — doctor consultation is required.

Propranolol se neend ki takleef kyun hoti hai?

Propranolol is lipid-soluble and enters the brain — this causes nightmares and sleep disturbances. Atenolol (water-soluble, less CNS penetration) may be better for this side effect — discuss with your doctor.
