Can I take Bisoprolol and Furosemide together?

Drug interaction guide

Taking bisoprolol and furosemide together can cause your blood pressure to drop lower than intended. This may make you feel dizzy, lightheaded, or faint, especially when standing up quickly. It can also increase the risk of your kidneys not working as well as they should or cause an imbalance in your body's salt levels (electrolytes).

Why this happens

Both medicines work to lower blood pressure but in different ways. Bisoprolol is a beta-blocker that slows the heart rate, while furosemide is a diuretic (water tablet) that removes excess fluid.

It is very common for these two medicines to be prescribed together, especially for heart failure. However, you should monitor your blood pressure regularly at home. To avoid dizziness, try to get up slowly from a sitting or lying position. Ensure you attend your scheduled blood tests to check your kidney function and salt levels. If you feel very dizzy, have a severe headache, or feel unusually tired, contact your doctor.
