Tenormin Side Effects: An Introduction
As with any medicine, side effects are possible with
Tenormin® (
atenolol). However, not everyone who takes it will experience side effects. In fact, most people tolerate the drug well. If people do develop side effects with Tenormin, in many cases, they are minor, meaning they require no treatment or are easily treated by you or a healthcare provider. Serious side effects are less common.
(This article discusses many, but not all, Tenormin side effects. Your healthcare provider can discuss a more complete list of side effects with you.)
