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.

“Warnings and precautions”),
 potassium sparing water tablets (diuretics) such as spironolactone,
eplerenone, triamterene or amiloride, potassium supplements, or
potassium-containing salt substitutes. Innozide may increase the
levels of potassium in your blood leading to high potassium levels.
This causes few signs and is usually seen by a test,

from being well controlled and may increase the level of
potassium in your blood
 medicines such as ephedrine, used in some cough and cold

pressure, shock, cardiac failure, asthma or allergies. If used with
Innozide these drugs may keep your blood pressure high,
