Fosinopril Sodium And Hydrochlorothiazide + Hydrochlorothiazide Interaction

Description

Drug Interactions Potassium supplements and potassium-sparing diuretics As noted above (“Derangements of Serum Electrolytes”), the net effect of fosinopril sodium and hydrochlorothiazide may be to elevate a patient’s serum potassium, to reduce it, or to leave it unchanged. Because renal clearance of lithium is reduced by thiazides, the risk of lithium toxicity is presumably raised further when, as in therapy with fosinopril sodium and hydrochlorothiazide tablets, a thiazide diuretic is coadministered with the ACE inhibitor. Fosinopril sodium and hydrochlorothiazide and lithium should be coadministered with caution, and frequent monitoring of serum lithium levels is recommended.
