This page explains what happens if Furosemide and Prednisolone are taken together, according to official sources.

Both prednisolone and furosemide cause massive urinary potassium excretion; co-administration frequently induces severe hypokalemia and cardiac instability.
Monitor serum potassium and magnesium closely. Initiate potassium supplementation or potassium-sparing diuretics under physician guidance.
Talk to your doctor or pharmacist about these two medicines; don't stop a prescribed medicine on your own.
