Metoprolol is a beta blocker commonly prescribed for high blood pressure, certain heart rhythm problems, angina, and heart failure. Like all medications, it can cause side effects, though many people tolerate it well.
Here are 10 commonly reported side effects of Metoprolol:
- Fatigue or tiredness
One of the most common effects, especially when starting treatment or increasing the dose. - Dizziness or lightheadedness
Can occur because the medication lowers blood pressure and slows the heart rate. - Slow heart rate (bradycardia)
Metoprolol is designed to slow the heart, but sometimes it can slow it too much. - Low blood pressure
May cause weakness, faintness, or feeling unsteady when standing up. - Cold hands and feet
Reduced blood flow to the extremities can make them feel cold. - Shortness of breath or exercise intolerance
Some people notice they tire more easily during physical activity. - Sleep disturbances
Insomnia, vivid dreams, or other sleep-related issues can occur. - Depression or mood changes
This is less common but has been reported by some patients. - Digestive symptoms
Such as nausea, diarrhea, constipation, or stomach discomfort. - Sexual side effects
Some people experience decreased libido or erectile dysfunction.
Serious side effects that warrant medical attention
Contact a healthcare professional promptly if you experience:
- Fainting
- Severe dizziness
- Very slow heartbeat
- Worsening shortness of breath
- Swelling of the legs with worsening symptoms
- Signs of an allergic reaction (rash, facial swelling, difficulty breathing)
Important note
Do not stop taking metoprolol suddenly without medical guidance. Abrupt discontinuation can cause a rebound increase in heart rate and blood pressure and may worsen heart conditions.
If you’re taking metoprolol and have a specific side effect you’re concerned about, I can help explain whether it’s a known effect of the medication and when it might require medical attention.
