Hydrochlorothiazide is a thiazide diuretic (water pill) and enalapril is an ACE inhibitor (ACE stands for angiotensin converting enzyme).

Hydrochlorothiazide and enalapril is a combination medicine used to treat hypertension (high blood pressure).

Hydrochlorothiazide and enalapril may also be used for purposes not listed in this medication guide.

You should not use this medicine if you are allergic to hydrochlorothiazide or enalapril, or if:

• you are allergic to sulfa drugs; or
• you are allergic to any ACE inhibitor (benazepril, captopril, fosinopril, lisinopril, moexipril, perindopril, quinapril, ramipril, trandolapril).

Do not take hydrochlorothiazide and enalapril within 36 hours before or after taking medicine that contains sacubitril (such as Entresto).

If you have diabetes, do not use hydrochlorothiazide and enalapril together with any medication that contains aliskiren (a blood pressure medicine).

You may also need to avoid taking hydrochlorothiazide and enalapril with aliskiren if you have kidney disease.
