3. Slow Heart Rate (Bradycardia)
Metoprolol intentionally lowers the heart rate to reduce cardiac workload and manage conditions like hypertension and arrhythmias. However, sometimes this effect is excessive, resulting in bradycardia—an abnormally slow heartbeat, typically below 60 beats per minute.
Symptoms of bradycardia may include increased fatigue, dizziness, lightheadedness, or even fainting spells. If you notice your pulse feels unusually slow or if these symptoms occur, it is important to record your heart rate and discuss this with your healthcare provider. They may adjust your dosage or consider alternative treatments.
4. Shortness of Breath
Some individuals taking metoprolol report mild shortness of breath or reduced exercise tolerance. This can be due to the heart pumping at a slower rate or less forcefully, which might limit oxygen delivery during physical activity.
In rare cases, metoprolol can affect the airways, especially in people with underlying respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD). If you develop new or worsening breathing difficulties, seek medical advice promptly.
5. Cold Hands and Feet
Cold extremities are a classic side effect of beta-blockers, including metoprolol. The medication can cause peripheral vasoconstriction, reducing blood flow to the fingers and toes. This often results in cold, sometimes numb, hands and feet, particularly in cooler weather.
While generally harmless, persistent or painful coldness should be evaluated by your healthcare provider to rule out other circulatory issues.
