An Introduction to Acebutolol Side Effects

As with any medicine, side effects are possible with acebutolol hydrochloride (Sectral®). However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
