An Overview of Propranolol Side Effects

As with any medicine, side effects are possible with propranolol hydrochloride (Inderal^®). However, not everyone who takes it will experience side effects. In fact, most people tolerate the drug quite well. If propranolol side effects do develop, in many cases, they are minor, meaning that they require no treatment or are easily treated by you or your healthcare provider. Serious side effects are far less common, but can still occur.

(This article covers many, but not all, of the possible side effects with propranolol. Your healthcare provider can discuss a more complete list of propranolol side effects with you.)
