Warnings to be aware of
  • This drug can cause serious and possibly fatal harm to an unborn baby if used during pregnancy. It is important to prevent pregnancy while taking this medication.
  • Consult your medical provider for more details and to discuss the use of reliable forms of birth control while taking this medication.
  • If you are planning pregnancy, become pregnant or think you may be pregnant, contact your medical provider right away.
What you should know about Benazepril/Hydrochlorothiazide
  • This medication is a combination of two drugs: an ACE inhibitor (Benazepril) and a "water pill"/diuretic (Hydrochlorothiazide).
  • It is used to treat high blood pressure (hypertension). Benazepril works by relaxing blood vessels, causing them to widen. The Hydrochlorothiazide diuretic increases the amount of urine you produce, which decreases excess water and salt in your body.
  • Lowering high blood pressure helps prevent strokes, heart attacks and kidney problems.
How to take Benazepril/Hydrochlorothiazide
  • Take this medication by mouth, usually once a day or as directed by your medical provider. You may take this drug with or without food. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day.
  • Drink adequate fluids to prevent dehydration. If you are on restricted fluid intake, consult your medical provider for further instructions.
  • The dosage is based on your medical condition and response to therapy. For the treatment of high blood pressure, it may take 2 weeks before the full benefit of this drug occurs or several weeks to months when used for congestive heart failure.
  • Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
  • If you are also taking Cholestyramine or Colestipol, take Benazepril/Hydrochlorothiazide at least 4 hours before or at least 4 to 6 hours after either of those drugs.
Potential side effects
  • You may experience dizziness, light-headedness, drowsiness, headache, fatigue, blurred vision, dry cough or vomiting as your body adjusts to the medication. If any of these effects persist or worsen, notify your medical provider or pharmacist right away.
  • Remember that this medication has been prescribed because your medical provider has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not experience serious side effects.
  • Angioedema is a rare but potential side effect. Symptoms include swelling of the lips, tongue, throat or neck. This is not considered an allergic reaction and can occur any time during treatment. This swelling can compromise the airway and be life threatening. Black patients and patients with a personal or family history of angioedema are at higher risk. If you believe you may be at higher risk, discuss alternative treatment options with your medical provider.

    • Eye pain
    • Symptoms of a high potassium blood level, such as muscle weakness or slow/irregular heartbeat
  • Tell your medical provider right away if you experience signs of kidney problems (such as change in the amount of urine) or seizures, both of which are highly unlikely but very serious.

    • Nausea or vomiting that doesn't stop
    • Loss of appetite
