Can I take Furosemide and Lansoprazole together?

Why this happens

Furosemide is a 'water tablet' that makes the kidneys flush out minerals like magnesium and potassium. Lansoprazole reduces stomach acid, which can sometimes interfere with how the body absorbs magnesium from food. When used together, they both deplete your mineral stores through different pathways.

You can take these medicines together, but your doctor may want to perform regular blood tests to check your mineral levels (especially magnesium and potassium). If you experience unusual muscle weakness, spasms, or a racing heart, contact your GP.
