Corzide

Generic Name: bendroflumethiazide/nadolol (BEN-droe-FLOO-me-THYE-a-zide/NAY-doe-lol)
Brand Name: Corzide

Do not suddenly stop taking Corzide. Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop Corzide. The risk may be greater if you have certain types of heart disease. Your doctor should slowly lower your dose over several weeks if you need to stop taking it. This should be done even if you only take Corzide for high blood pressure. Heart disease is common and you may not know you have it. Limit physical activity while you are lowering your dose. If new or worsened chest pain or other heart problems occur, contact your doctor right away. You may need to start taking Corzide again.


Corzide is used for:

Treating high blood pressure.

Corzide is a beta-blocker and diuretic combination. It works by decreasing the force and slowing down the heartbeat, helping the heart beat more regularly and reducing the amount of work the heart has to do. It also increases the elimination of excess fluid, which helps to decrease blood pressure.

Do NOT use Corzide if:

  • you are allergic to any ingredient in Corzide or to sulfonamide medicines (eg, glyburide, probenecid, sulfamethoxazole)
  • you have uncontrolled heart failure or a very slow and irregular heartbeat (eg, heart block)
  • you are unable to urinate
  • you have a history of asthma
  • you are taking dofetilide or mibefradil

Contact your doctor or health care provider right away if any of these apply to you.
