Tenormin Side Effects
Depression, tiredness, and shortness of breath are a few common side effects of Tenormin. Some of the medicine's uncommon side effects include allergic reactions, headache, and an increase in liver enzymes. Some side effects should be reported to your healthcare provider, including difficulty breathing, chest pain, and irregular heartbeat.
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.
