Summary
Furosemide increases urinary losses of phosphate and may lower serum phosphate levels. This can offset the effect of intravenous phosphate replacement, so the expected rise in serum phosphate may be smaller.
What this interaction means in plain words
Furosemide and Sodium phosphates have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Furosemide increases renal excretion of phosphate along with other electrolytes.
What to do
Check serum phosphate, calcium, magnesium and potassium during phosphate replacement. Adjust the phosphate dose accordingly.
