What is a common side effect of beta-blockers?

Beta-blockers are a class of medications commonly used to manage cardiovascular conditions such as hypertension, heart failure, and arrhythmias. One of the well-known side effects of beta-blockers is fatigue. This occurs because beta-blockers reduce the sympathetic nervous system activity, which can lead to decreased heart rate and cardiac output, resulting in a feeling of tiredness or reduced energy levels in some patients.

Fatigue is often more pronounced in people who are taking higher doses or those who are sensitive to the effects of the medication. While beta-blockers can cause various side effects, including weight gain and dizziness in some individuals, fatigue is frequently reported and noted as a common side effect across different beta-blocker formulations. Understanding this side effect is important for monitoring patient response to the medication and addressing quality of life concerns.
