Lotensin HCT is a combination blood pressure medication for adults. It contains benazepril (an angiotensin-converting enzyme (ACE) inhibitor) and hydrochlorothiazide (a thiazide diuretic). It's available as a brand name and lower-cost generic tablet that's taken by mouth once per day. The dosage will generally depend on how high your blood pressure is and if you're taking, or have recently taken, other blood pressure medications. Some common side effects of Lotensin HCT (benazepril / hydrochlorothiazide) include dizziness, tiredness, and headache.
High blood pressure in adults
Lotensin HCT is a combination of two medications that work together to lower blood pressure:
Benazepril is an angiotensin-converting enzyme (ACE) inhibitor. It relaxes your blood vessels by blocking a protein (ACE) that normally squeezes your blood vessels.
Hydrochlorothiazide is a thiazide diuretic, which is a water pill. It works in your kidneys to remove extra water and salt. This helps lower blood pressure.
