Nadolol Side Effects

Decreased heart rate, fatigue, and dizziness are among the most common side effects reported with nadolol. Problems that have been reported in less than 1 percent of people (and may or may not be related to the medication itself) include diarrhea, nausea, and hair loss. Some side effects of this medicine are potentially serious and require medical attention, including fainting, rapid weight gain, and depression.

An Introduction to Nadolol Side Effects

As with any medicine, side effects are possible with nadolol (Corgard®). 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.
(This article covers many, but not all, of the possible side effects with nadolol. Your healthcare provider can discuss a more complete list of nadolol side effects with you.)
