Can I take Furosemide and Metoprolol together?

Why this happens

Both medicines work to lower blood pressure but in different ways. Furosemide is a 'water tablet' (diuretic) that removes excess fluid, while metoprolol is a beta-blocker that slows the heart rate. When used together, their effects add up, which can lead to an exaggerated drop in blood pressure. Furosemide can also lower potassium levels, which can sometimes affect how heart medications work.

You can take these together, but you should be careful. When you first start this combination or if your dose is increased, get up slowly from a bed or chair to avoid dizziness. Monitor your blood pressure at home if your doctor has asked you to. If you feel very dizzy, faint, or notice a very slow heartbeat, contact your doctor. Your doctor may want to perform regular blood tests to check your kidney function and salt levels (like potassium).
