What side effect should be discussed with a client prescribed metoprolol (Lopressor)?

When discussing metoprolol, a beta-blocker primarily used to manage hypertension and heart conditions, it is essential to highlight fatigue as a side effect. Beta-blockers function by blocking the effects of adrenaline, leading to a decrease in heart rate and blood pressure. This mechanism can often result in patients experiencing feelings of tiredness or fatigue.

The presence of fatigue may be due to the reduced heart rate and the overall calming effect the medication has on the cardiovascular system. It can also impact physical activity levels, as patients might feel less energetic or more lethargic as their body adjusts to the medication.

Understanding this side effect is crucial for patients, as it can influence their lifestyle and activities. They should be informed so they can manage their expectations regarding their energy levels after starting therapy with metoprolol.
