Chlorthalidone 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
Diuretic-related volume depletion can increase hypotension or renal concerns when an ACE inhibitor or ARB starts.
Clinical significance and safety
Chlorthalidone and Fosinopril: These medicines are often deliberately combined. Monitoring is especially important at initiation, after changes, or during vomiting, diarrhoea or dehydration. The clinician may review blood pressure, renal function and electrolytes. Report severe dizziness or fainting; do not change treatment yourself.
Using this information
