Metoprolol Side Effects

Individuals who have high blood pressure may be prescribed metoprolol. This medication is used to prevent kidney problems, strokes, chest pains and heart attacks. After an individual suffers a heart attack, they can be prescribed metoprolol to lower their future risk of having a heart attack. Metoprolol works by stopping natural chemicals in the body that can cause heart attacks. In some occasions, a doctor might prescribe metoprolol to treat migraine headaches, tremors and irregular heartbeats.

Side Effects

Like most drugs, metoprolol carries a few side effects that patients should be wary about. It can decrease sexual ability, lower libido and cause diarrhea.
