The 10 Metoprolol Side Effects You Should Know About
Metoprolol is a beta-blocker commonly prescribed for high blood pressure, angina, heart failure, certain abnormal heart rhythms, and after a heart attack. Like all medicines, it can cause side effects, although many people tolerate it well.
Here are 10 effects worth knowing:
- Dizziness or lightheadedness — Metoprolol lowers heart rate and blood pressure, which can make some people feel dizzy, particularly when standing up.
- Tiredness or weakness — Fatigue is a commonly reported effect, especially when first starting treatment.
- Slow heartbeat — Because metoprolol slows the heart, your pulse may become lower than usual. A very slow or irregular heartbeat requires medical attention.
- Low blood pressure — Some people may experience weakness, dizziness, or fainting if blood pressure becomes too low.
- Diarrhea or digestive problems — Diarrhea is listed among the possible side effects.
- Dry mouth — Some people develop a dry mouth while taking the medication.
- Sleep or mood changes — Sleep disturbance, nightmares, depression, and other central nervous system effects have been reported with metoprolol.
- Cold hands and feet — Reduced peripheral circulation can sometimes make the extremities feel unusually cold.
- Sexual difficulties — Erectile dysfunction has been reported with beta-blockers, including metoprolol.
- Shortness of breath or swelling — These can be signs of a more serious problem, particularly when accompanied by rapid weight gain or worsening heart symptoms. Seek medical attention promptly
