Tiredness is one of the most commonly reported effects of metoprolol. Some people notice that they feel unusually drained, need more rest, or cannot exercise as comfortably as before.
This may be more noticeable when treatment begins or after the dose is increased. The body sometimes adjusts over the following days or weeks, but persistent or severe fatigue should be discussed with a healthcare professional.
Fatigue accompanied by shortness of breath, swelling, chest discomfort, confusion, or fainting requires more urgent evaluation.
## 2. Dizziness and Light-Headedness
Metoprolol can lower blood pressure and slow the heart rate. As a result, some people feel dizzy, weak, or light-headed, especially when standing up quickly.
To reduce this problem:
* Rise slowly from bed or a chair.
* Sit or lie down if you feel faint.
* Avoid driving until you know how the medication affects you.
* Ask your doctor before increasing your fluid or salt intake, particularly if you have heart failure or kidney disease.
* Limit alcohol because it may worsen dizziness.
Frequent falls, fainting, or severe dizziness should not be ignored.
3.
A Slower-Than-Usual Heart Rate
A lower pulse may be an intended effect of metoprolol. However, an excessively slow heartbeat can cause weakness, dizziness, confusion, fainting, chest discomfort, or difficulty breathing.
There is no single pulse number that is dangerous for everyone. Athletes, older adults, and people with heart conditions may have different safe ranges. Ask your healthcare provider what heart rate is appropriate for you and when you should seek help.
Do not change the dose based only on a home pulse reading unless a clinician has given you specific instructions.
## 4. Cold Hands and Feet
Beta-blockers can reduce circulation to the extremities, leaving the fingers and toes cold, pale, or occasionally numb.
Warm socks, gloves, gentle movement, and avoiding tobacco may help. Caffeine can also narrow blood vessels in some people and may make the sensation worse.
Contact your doctor if a hand or foot becomes unusually painful, persistently discolored, or markedly colder than the other side.
