Accuretic is a prescribed medication for treating hypertension (high blood pressure) alone or in combination with other medicines. 

Accuretic contains two medication that works together to regulate blood pressure: 

  • Quinapril, an angiotensin-converting enzyme (ACE) inhibitor, works by relaxing blood vessels to improve blood flow 
  • Hydrochlorothiazide, a thiazide diuretic, works by increasing urine production, facilitating the elimination of excess salt and water from the body 

Controlling high blood pressure lowers the likelihood of fatal and nonfatal cardiovascular events, including strokes and myocardial infarctions. 

Uses and Dosage 

Before taking Accuretic and each time you refill your prescription, carefully read its medication guide and patient information leaflet. Do not hesitate to seek advice from your doctor or pharmacist for any inquiries or concerns. 

Accuretic dosage is individualized based on the patient’s medical condition and response to treatment.  

Typically, Accuretic is taken once daily in the morning as directed by a physician, regardless of food intake. Taking this medication close to bedtime may result in the need to wake up for urination, so it is advisable to take it at least 4 hours before bedtime. 

If you are on medications such as cholestyramine or colestipol to reduce cholesterol, ensure a gap of 4 to 6 hours before or after taking Accuretic. 

Take Accuretic regularly, exactly as prescribed, around the same time each day. Do not increase or decrease the dosage or take it more often than directed.  

Do not discontinue intake of Accuretic without consulting your doctor, even if you feel well, as high blood pressure usually does not cause noticeable symptoms.

Prevent overheating or dehydration when exercising or in hot weather by maintaining adequate fluid intake. Adhere to your physician’s guidance regarding how much fluids to drink. In certain instances, overhydration can be as harmful as dehydration.
