What Innozide is and what it is used for
Innozide contains enalapril maleate and hydrochlorothiazide:
enalapril belongs to a group of medicines called angiotensin
converting enzyme inhibitors (ACE inhibitors), which work by
widening your blood vessels
hydrochlorothiazide belongs to a group of medicines known as water
tablets (diuretics), which increase the volume of urine you produce.
The effect of these medicines is to lower your blood pressure.
Innozide is used to treat high blood pressure (hypertension). Taking both
medicines that Innozide contains can increase their effect compared to
taking just one.

with difficulty in swallowing or breathing. You should not take this
medicine if you have had these types of reactions without a known
cause, or if you have been diagnosed with hereditary or idiopathic
