Can I take Bisoprolol and Eplerenone together?

Why this happens

Both medicines affect how your body handles minerals and fluids. Eplerenone is a 'potassium-sparing' diuretic that prevents your body from flushing out potassium. Bisoprolol can also cause potassium levels to rise by affecting how it moves in and out of your cells. Additionally, both drugs lower blood pressure, so their combined effect is stronger than taking either one alone.

You can take these medicines together, but your doctor must monitor you closely. You will need regular blood tests to check your potassium levels and kidney function, especially when starting or changing doses. Avoid using salt substitutes that contain potassium (often labelled as 'low sodium' salt) and speak to your doctor if you feel dizzy, have palpitations, or experience muscle weakness.
