6. Shortness of breath
Some patients taking metoprolol experience mild shortness of breath during normal activities. This occurs because beta-blockers can affect lung function by constricting airways, especially in people with underlying respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD).
Any new or worsening breathlessness should be carefully evaluated, as it might indicate the need to adjust treatment or investigate other causes.
7. Leg and ankle swelling
Peripheral edema, or swelling in the legs and ankles, can develop due to fluid retention while on metoprolol. This may cause discomfort, heaviness, and tightness in the affected areas.
Swelling that appears suddenly, is painful, or accompanied by redness and warmth should be evaluated promptly to exclude more serious conditions like blood clots or infection.
Management tips: Elevate your legs when possible, avoid prolonged standing, and discuss compression stockings with your healthcare provider if swelling persists.
8. Digestive changes
Metoprolol may cause gastrointestinal side effects such as diarrhea, nausea, or mild abdominal discomfort. These symptoms often occur early in treatment and may improve as your body adjusts.
If diarrhea is severe, persistent, or accompanied by dehydration, medical advice is necessary to prevent complications.
