Moexipril belongs to a group of drugs called angiotensin-converting enzyme (ACE) inhibitors. Moexipril works by blocking the ACE enzyme, which helps blood vessels to relax and lowers blood pressure. Hydrochlorothiazide belongs to a group of drugs called thiazide diuretics, which work by stopping reabsorption of salt into your body. This prevents fluid from building up in the body.

This medication comes in tablet form. It is given once or twice daily, one hour before meals.

Common side effects of moexipril and hydrochlorothiazide include dizziness, tiredness (fatigue), and cough. Do not drive or operate heavy machinery until you know how this medication affects you.
