Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop taking metoprolol/hydrochlorothiazide extended-release tablets. 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 metoprolol/hydrochlorothiazide extended-release tablets 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 metoprolol/hydrochlorothiazide extended-release tablets again.
Metoprolol/ hydrochlorothiazide extended-release tablets are used for:
Treating high blood pressure.
Metoprolol/hydrochlorothiazide extended-release tablets are a beta-adrenergic blocking agent (beta-blocker) and diuretic combination. The beta-blocker works by slowing down the heartbeat, helping the heart beat more regularly, and reducing the amount of work the heart has to do. The diuretic increases the elimination of excess fluid, which helps to decrease blood pressure.
Do NOT use metoprolol/ hydrochlorothiazide extended-release tablets if:
- you are allergic to any ingredient in metoprolol/hydrochlorothiazide extended-release tablets, to another beta-blocker (eg, propranolol), or to a sulfonamide medicine (eg, sulfamethoxazole)
- you have shock caused by serious heart problems or uncontrolled heart failure
- you have a very slow heartbeat, a certain type of irregular heartbeat (sick sinus syndrome), or second- or third-degree heart block and you do not have a pacemaker
- you are unable to urinate
- you are taking dofetilide
Contact your doctor or health care provider right away if any of these apply to you.
