Does metoprolol make you sleepy?
Yes, metoprolol can make you sleepy. Metoprolol is available as immediate-release and extended-release tablets. It is estimated that around 10 in 100 people who take the immediate-release version (metoprolol tartrate) experience tiredness as a side effect.
Tiredness was also reported as a side effect in more than 2% of patients who took the extended-release version (metoprolol succinate) during clinical trials for high blood pressure and angina. In one study of patients taking it for high blood pressure, 5% of patients taking doses above 200 mg per day reported feeling tired as a side effect. This was compared to about 4% of patients who took 25 mg to 100 mg per day, and around 1% of patients who took a placebo.
Why does metoprolol make you tired?
It isn’t fully clear why beta blockers like metoprolol make you feel tired. One reason may be because beta blockers slow down your heart rate and lower your blood pressure. Your body might adjust to the medication, but if you feel so tired that it is interfering with your daily activities you should let your healthcare provider know. They might be able to adjust your dose, change your medications, or recommend other ways to feel more energized.
In the meantime, some things you can do to feel less tired include:
- Get plenty of sleep at night
- Take rest breaks during the day
- Eat a balanced diet
- Schedule activities during the times of day that you have the most energy

Metoprolol Succinate vs Tartrate: What's the difference between them?
Metoprolol is available as two different salts: metoprolol tartrate and metoprolol succinate.

As a result, there are differences in the dosages and indications for both metoprolol tartrate and metoprolol succinate and they are not considered interchangeable. Continue reading
