Propranolol Side Effects
Insomnia, low blood sugar, and vomiting are among the more common side effects of propranolol. Serious problems that should be reported to your healthcare provider immediately include dizziness, lightheadedness, or fainting spells. However, most people have no problems when taking it. If side effects occur, they are often minor and easily treated.
An Overview of Propranolol Side EffectsAs with any medicine, side effects are possible with propranolol hydrochloride (Inderal®). However, not everyone who takes it will experience problems. In fact, most people tolerate it quite well. If side effects do develop, in many cases, they are minor, meaning they require no treatment or are treated easily by you or your healthcare provider. Serious reactions 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 with you.)
