Summary
Aqueous penicillin G is given as a potassium salt in many products, delivering a potassium load that adds to amiloride's potassium retention. High doses can cause hyperkalemia, especially in renal impairment.
What this interaction means in plain words
Amiloride and Penicillin g aqueous can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Potassium load from penicillin G potassium combined with reduced renal potassium excretion from amiloride.
What to do
Check which salt is used and monitor serum potassium and renal function during therapy. Use the sodium salt or hold amiloride if hyperkalemia is a concern.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
