Propranolol, a widely prescribed beta-blocker, is used to treat a variety of conditions, including high blood pressure, angina, and certain heart rhythm disorders. While it can be an effective medication for managing these conditions, it's essential to be aware of the potential side effects that can occur. In this article, we'll explore the common and less common side effects of propranolol, as well as some important considerations to keep in mind when taking this medication.
Propranolol works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This can help to slow your heart rate, reduce blood pressure, and decrease the workload on your heart. However, as with any medication, propranolol can cause side effects in some people. Some side effects can be mild and temporary, while others can be more severe and require medical attention.

Less Common but More Serious Side Effects
Less common side effects of propranolol can be more severe and require immediate medical attention. These side effects can affect up to 1% of people taking the medication and may include:
