Amiloride and Fosinopril: interaction and safety
This source-based reference is not a personal treatment recommendation. The relevance and management of an interaction depend on the exact products, route, dose and clinical situation.
Interaction mechanism
An ACE inhibitor or ARB with a potassium-sparing diuretic can reduce potassium excretion and cause hyperkalaemia.
Clinical significance and safety
Amiloride and Fosinopril: Use together only when the prescriber considers it appropriate, with close potassium and kidney-function monitoring. Do not add potassium supplements or potassium-containing salt substitutes without advice. Report muscle weakness or palpitations; fainting or a markedly slow or irregular pulse needs urgent assessment. Do not alter prescribed medicines yourself.
