Blood Pressure Home > Toprol Side Effects
While most people have no problems, side effects can occur with Toprol. Tiredness, dizziness, and a slow heart rate are some of the more commonly reported problems. Rare side effects include weight gain, increased liver enzymes, and impotence. Potentially serious side effects of Toprol that you should report to your healthcare provider include unexplained swelling or sudden weight gain, chest pain, unexplained skin rash, and an irregular heartbeat.
As with any medicine, side effects can occur with Toprol® (short for Toprol-XL®). However, not everyone who takes the drug will experience problems. In fact, most people tolerate it well. If 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 less common.
(This article covers many, but not all, of the possible side effects with Toprol. Your healthcare provider can discuss a more complete list of Toprol side effects with you.)
Toprol has been studied extensively in people with high blood pressure, angina, and congestive heart failure. In these clinical studies, side effects are always documented and compared to those that occur in a similar group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they occur, and how they compare to the group not taking the medicine.
Based on these studies, the most common Toprol side effects include:
- A slow heart rate -- in up to 16 percent of people
- Tiredness -- up to 10 percent
- Dizziness -- up to 10 percent
- Diarrhea -- up to 5 percent
- Itching or unexplained rash -- up to 5 percent
- Depression -- up to 5 percent (see Toprol and Depression)
- Shortness of breath -- up to 3 percent.
Some other common side effects (occurring in more than 1 percent of people taking Toprol) include but are not limited to:
- Cold, tingling, or numbness in the hands or feet
- Congestive heart failure
- Swelling of the arms, legs, hands, or feet
- Low blood pressure
- Shortness of breath
- Dry mouth
