Do not suddenly stop taking Lopressor HCT . Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop taking Lopressor HCT . 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 Lopressor HCT 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 Lopressor HCT again.

Lopressor HCT is used for:

Treating high blood pressure.

Lopressor HCT 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 Lopressor HCT if:

  • you are allergic to any ingredient in Lopressor HCT , to another beta-blocker (eg, propranolol), or to a sulfonamide medicine (eg, sulfamethoxazole, probenecid, glyburide)
  • you have a very slow heart rate (eg, bradycardia), certain types of irregular heartbeat (eg, atrioventricular [AV] block, sick sinus syndrome), moderate to severe heart failure, very low systolic blood pressure (less than 100 mm Hg), or severe blood circulation problems
  • you are unable to urinate
  • you are taking another beta-blocker (eg, propranolol), dofetilide, or mibefradil

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