Does metoprolol make you sleepy?

Medically reviewed by Kristianne Hannemann, PharmD. Last updated on Sep 2, 2025.

Official Answer by Drugs.com

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.

How long does Metoprolol stay in your system after you stop taking it?
