hydrochlorothiazide and enalapril
What is hydrochlorothiazide and enalapril?
Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Enalapril is an ACE inhibitor. ACE stands for angiotensin converting enzyme. Enalapril lowers blood pressure and also relieves symptoms of fluid retention.
