Toprol Side Effects

While most people tolerate Toprol well, side effects can occur during treatment with the drug. Tiredness, dizziness, and a slow heart rate are some of the more commonly reported side effects. Rare side effects can include weight gain, increased liver enzymes, and impotence. There are also a number of more serious Toprol side effects that you should report to your healthcare provider right away, including unexplained swelling or sudden weight gain, chest pain, unexplained skin rash, and an irregular heartbeat.

 

Toprol Side Effects: An Overview

As with any medicine, there are possible side effects with Toprol® (short for Toprol-XL®). However, not everyone who takes Toprol will experience side effects. In fact, most people tolerate the medicine well. When people do develop Toprol 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 a lot less common but can still occur.
