Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Propranolol is a beta blocker medication. It is used to treat high blood pressure, a number of types of irregular heart rate, thyrotoxicosis, capillary hemangiomas, performance anxiety, and essential tremors. Alternative medication for it are other beta-blockers like metoprolol and nebivolol. However, before you change it, you need to consult Physician for the proper dosage and administration as per your needs. Hope I have answered your query. Let me know if I can assist you further.
