How effective are beta blockers for hyperthyroidism?
Very effective! Propranolol is usually prescribed along with a anti-thyroid drug and after 7 days of around 30mg a day the beta blocker will counter act the overactive behaviour of the thyroid thus stablizing your body and after 3/4 weeks the patient should feel “normal” once again, however the drug must not be stopped immediately, this will enduse symptoms to return even worse or even cause heart failure. Beta Blockers must be gradually reduceds over a period of weeks. The Beta Blocker should be stopped once the anti-thyroid drug reduces the thryroid action to a normal rate.
