Although most people don't have any problems with penbutolol, side effects are possible. In clinical studies, the most common reactions that were reported with this medication included headache, fatigue, and dizziness. Side effects are generally mild, but you should seek medical attention right away if you experience lightheadedness or fainting, chest pain, or rapid weight gain.
As with any medicine, side effects are possible with penbutolol sulfate (Levatol®). However, not everyone who takes the medication will experience 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.
(This article covers many, but not all, of the possible side effects with penbutolol. Your healthcare provider can discuss a more complete list of side effects with you.)
