Does lisinopril have sulfa in it?

Actually, this is not a silly question, and your answer isn't that simple. Lisinopril is often coupled with HCTZ (hydrochlorothiazide) as a diuretic to treat high blood pressure. HCTZ is, in fact, a sulfonamide. Your doctor must specify Lisinopril without. HCTZ. I have an allergy to Sulfa, hence to HCTZ. It made my feet, ankles and hands swell to a dangerous level mimicking symptoms of blood clots. Especially in my case when the swelling generally presented in one foot/ankle or the other at a time. You can also look at the molecular structures of most drugs in the patient information pamphlet or on the internet. Sulfonamides appear as a capital 'S' so double check with your doctor, pharmacist, or poison control before taking. Best of luck to you!

I have a deadly allergy to sulfa. YES Lisinopril is most commonly prescribed with a diuretecic component that contains sulfa. A doctor prescribed it for me, and thank God my pharmacist noticed it, and the doctor apologized and sent a new prescription for Lisinopril without the water pill in it (which contains sulfa). The pharmacist explained that the 4 letters that followed it was the water pill component that contains sulfa. The doctor had not paid attention to my chart, and regularly prescribed Lisinopril with the water pill component (as do most doctors).
