In general, lisinopril should not be taken with potassium supplements or diuretics that conserve potassium [for example, hydrochlorothiazide/triamterene (Dyazide)], since blood potassium levels may rise to dangerous levels.
PREGNANCY: Lisinopril should not be taken during pregnancy because fetuses and neonates have died when lisinopril was administered during pregnancy.
NURSING MOTHERS: It is not known whether lisinopril is excreted in breast milk.
