Propranolol hydrochloride is a prescription beta-blocker tablet used to treat high blood pressure, angina (chest pain), irregular heartbeats, migraines, tremors, and anxiety symptoms by slowing heart rate and reducing cardiovascular strain. Common doses range from 10mg to 80mg, typically taken with or without food.

Key Information:

• Uses: Hypertension, angina, arrhythmia, migraine prevention, tremor reduction, performance anxiety, and hypertrophic subaortic stenosis.

• How it works: It is a non-selective beta-adrenergic blocker that decreases the heart's oxygen demand and lowers blood pressure.

• Dosage: Varies widely; 40mg twice daily is common for tremors, while 10mg-40mg doses are used for anxiety or migraines.
