Atenolol Side Effects: An Introduction
As with any medicine, there are possible side effects with
atenolol (
Tenormin®). However, not everyone who takes atenolol will experience side effects. In fact, most people tolerate atenolol well. When people do develop atenolol side effects, 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 but can still occur.
(The atenolol side effects discussed below are not a complete list of side effects reported with atenolol. Your healthcare provider can discuss a more complete list of side effects with you.)
