1. Fatigue and tiredness
Fatigue is one of the most frequently reported side effects of metoprolol. Because this medication slows your heart rate and reduces cardiac output, your body may initially respond with decreased energy levels. You might find yourself feeling unusually tired even during routine activities that previously felt easy.
This effect occurs as your cardiovascular system adjusts to the lower workload and slower pulse. While it can be frustrating, this tiredness often lessens over a few weeks as your body adapts. To help manage fatigue, consider pacing yourself throughout the day and prioritizing restful sleep.
2. Dizziness and lightheadedness
Dizziness or lightheadedness, especially when standing up quickly, is a common side effect linked to metoprolol’s blood pressure-lowering effects. This happens because the medication can cause a temporary drop in blood pressure upon standing, known as orthostatic hypotension.
To minimize this, rise slowly from sitting or lying positions and avoid sudden movements. Staying well hydrated and avoiding alcohol can also help maintain stable blood pressure. If dizziness becomes frequent or severe, discuss it with your healthcare provider as dosage adjustments might be necessary.
