Atenolol Side Effects
There are a number of potential side effects that may occur during treatment with atenolol. A few common atenolol side effects include shortness of breath; cold, tingling, or numbness in the hands or feet; and dizziness. Some serious side effects that you should report to your healthcare provider immediately include sudden weight gain, chest pain, or irregular heartbeat.
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.
