Toprol® is a member of a family of drugs called beta blockers. It is commonly used to treat high blood pressure, angina, and congestive heart failure. The most common Toprol® side effects include bradycardia, also known as slow heart rate; diarrhea; dizziness; itching or rashes; shortness of breath; and fatigue. Most of these side effects are minor and should diminish over time as the body becomes accustomed to the drug.

In addition to the most common Toprol® side effects, there are other relatively common side effects. These include constipation; dry mouth and eyes; headaches; heartburn; lightheadedness; muscle aches; nausea or vomiting; stomach pain; trouble sleeping; and a feeling of fatigue, weakness, or drowsiness. For the comparatively few people who do suffer from any of these side effects, they should lessen over time. If they do occur and become persistent, a physician should be consulted.

A number of Toprol® side effects are considered serious. These include chest pain; fainting; mood changes or confusion; a pounding feeling in the chest; severe dizziness or lightheadedness; shortness of breath; irregular heartbeat; swelling of the arms, hands, and feet; vision changes; and yellowing of the skin or eyes. There are also those who experience allergic reactions to Toprol®, which can cause a rash, hives, difficulty breathing, a tight feeling in the chest, and swelling. Anyone experiencing any of these reactions should seek professional medical attention immediately.


Individuals have reported a number of additional side effects; however, as these reported problems did not occur within the controls of a study, their frequency, severity, and even proof that they are really Toprol® side effects are unknown. These additional potential side effects of using the drug include cold extremities; low blood pressure; heart palpitations; insomnia; ringing in the ears; temporary hair loss; worsening of psoriasis; sensitivity to light; problems with taste; and blurred vision. Further, there are a number of potential mental and sexual side effects associated with the drug, including nightmares; anxiety; hallucinations; short-term memory loss; decreased libido; and impotence. Like all reactions, these should be reported to a physician or, if they feel life-threatening, treated by medical professionals immediately.

Though not documented as Toprol® side effects, potential side effects and reactions have occurred with drugs similar to Toprol®. These include depression leading to catatonia; disorientation; emotional lability; clouded sensation; and severe respiratory distress. Anyone experiencing these effects should seek immediate medical attention.
