Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. ( 1.1 ) Angina Pectoris. ( 1.2 ) Myocardial Infarction, to reduce the risk of cardiovascular mortality when used in conjunction with intravenous metoprolol therapy in patients with definite or suspected acute myocardial infarction in hemodynamically stable patients. ( 1.3 ) 1.1 Hypertension Metoprolol tartrate tablets are indicated for the treatment of hypertension in adult patients, to lower blood pressure. …

• Administer once daily with food or after a meal
• Titrate at weekly or longer intervals as needed and tolerated
• Hypertension: Recommended starting dosage is 100 mg daily, in single or divided doses
• Angina Pectoris: Recommended starting dosage is 100 mg daily, given as two divided doses
• Myocardial Infarction: The starting dosage depends upon tolerance of intravenous metoprolol, see full prescribing information
• Hypertension Individualize the dosage of metoprolol tartrate tablets
• Metoprolol tartrate tablets should be taken with or immediately following meals
• The usual initial dosage is 100 mg daily in single or divided doses
• Adjust dosage at weekly (or longer) intervals until optimum blood pressure reduction is achieved
• In general, the maximum effect of any given dosage level will be apparent after 1 week of therapy
• The effective dosage range of metoprolol tartrate tablets is 100 mg to 450 mg per day
• Dosages above 450 mg per day have not been studied

Metoprolol tartrate tablets are contraindicated in severe bradycardia, second- or third-degree heart block, cardiogenic shock, systolic blood pressure

Catecholamine-depleting drugs may have an additive effect when given with beta-blocking agents. ( 7.1 ) Patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction. ( 7.2 ) CYP2D6 Inhibitors are likely to increase metoprolol concentration. ( 7.3 ) Concomitant use of glycosides, clonidine, and diltiazem and verapamil with beta-blockers can increase the risk of bradycardia. ( 7.4 ) Beta-blockers including metoprolol, may exacerbate the rebound hypertension that can follow the withdrawal of clonidine. …

Abrupt cessation may exacerbate myocardial ischemia. ( 5.1 ) Heart Failure: Worsening cardiac failure may occur. ( 5.2 ) Bronchospastic Disease: Avoid beta-blockers. ( 5.3 ) Pheochromocytoma: Initiate therapy with an alpha blocker. ( 5.4 ) Major Surgery: Avoid initiation of high-dose extended-release metoprolol in patients undergoing non-cardiac surgery. Do not routinely withdraw chronic beta-blocker therapy prior to surgery. ( 5.5 , 6.1 ) Diabetes: May mask symptoms of hypoglycemia.( 5.6 ) Thyrotoxicosis: Abrupt withdrawal in patients with thyrotoxicosis might precipitate a thyroid storm. ( 5.7 ) Peripheral Vascular Disease: Can aggravate symptoms of arterial insufficiency. …

Untreated hypertension and myocardial infarction during pregnancy can lead to adverse outcomes for the mother and the fetus (see Clinical Considerations). …

Signs and Symptoms - Overdosage of metoprolol may lead to severe bradycardia, hypotension, and cardiogenic shock. Clinical presentation can also include: atrioventricular block, heart failure, bronchospasm, hypoxia, impairment of consciousness/coma, nausea and vomiting. Treatment – Consider treating the patient with intensive care. Patients with myocardial infarction or heart failure may be prone to significant hemodynamic instability. Beta-blocker overdose may result in significant resistance to resuscitation with adrenergic agents, including beta-agonists. …

Take it when you remember, unless it is nearly time for the next dose. Then skip the missed one. Never take two doses at once to make up for it. Check your leaflet, as some medicines are different.
