Can I take Omeprazole and Spironolactone together?

Why this happens

Both medications can independently influence how the body handles electrolytes. Spironolactone is a 'potassium-sparing' diuretic that prevents the body from flushing out potassium. Omeprazole can sometimes affect magnesium and potassium levels through its effect on the kidneys and stomach acid. When used together, there is a small additive risk of potassium levels rising too high.

What you should do

You can usually take these two medicines together, but you should have your blood monitored regularly by your doctor to check your kidney function and potassium levels. If you experience symptoms like muscle weakness, an irregular heartbeat, or tingling sensations, contact your doctor. Avoid using salt substitutes that contain potassium (often labelled as 'low sodium' salt) unless your doctor tells you otherwise.
