Benicar HCT, also known as Benicar Hydrochlorothiazide, is used to treat hypertension or high blood pressure. Keeping blood pressure under control prevents strokes, heart attacks, and kidney problems. There are two medications contained in this product: olmesartan and hydrochlorothiazide. It works by relaxing blood vessels so that blood can flow easier. Olmesartan is an angiotensin receptor blocker (ARB). The diuretic hydrochlorothiazide helps your body eliminate extra salt and water by making more urine.

When other blood pressure medicines have failed or stopped working, Benicar HCT is usually given.


The term hypertension refers to chronic conditions characterized by elevated blood pressure levels. As the heart pumps blood throughout the body, blood exerts force against the walls of the arteries. It is typically expressed as systolic pressure (the highest value) and diastolic pressure (the lowest value). The regular blood pressure reading is 120/80 mmHg.

If left untreated, hypertension can cause severe health complications, including heart disease, stroke, kidney damage, and even vision loss. To maintain overall health and well-being, blood pressure must be controlled.

The two types of hypertension are primary (essential) and secondary hypertension. Genetic and environmental factors lead to primary hypertension, which develops over time. Conversely, secondary hypertension is often caused by underlying medical conditions such as kidney disease, hormonal imbalances, or medications.

Several risk factors contribute to the development of hypertension. These include:

  • Age: The risk of hypertension increases with age.
  • Family History: A family history of hypertension can predispose individuals to the condition.
  • Lifestyle Factors: Unhealthy eating habits, lack of physical activity, excessive alcohol consumption, and smoking can elevate blood pressure.
  • Obesity: Being overweight strains the cardiovascular system and can lead to hypertension.
