Switching from immediate-release to extended-release: Use same total daily dose of metoprolol Switching between oral and IV dosage forms: Equivalent beta-blocking effect is achieved in 2.5:1 (oral-to-IV) ratio Dizziness (10%) Headache (10%) Tiredness (10%) Depression (5%) Diarrhea (5%) Pruritus (5%) Bradycardia (9%) Rash (5%) Dyspnea (1-3%) Cold extremities (1%) Constipation (1%) Dyspepsia (1%) Heart failure (1%) Hypotension (1%) Nausea (1%) Flatulence (1%) Heartburn (1%) Xerostomia (1%) Wheezing (1%) Bronchospasm (1%) Anxiety/nervousness Hallusinations Paresthesia Hepatitis Vomiting Arthralgia Male impotence Reversible alopecia Agranulocytosis Dry eyes Worsening of psoriasis Pyronie’s disease Sweating Photosensitivity Taste disturbance Lopressor and Toprol XL only Ischemic heart disease may be exacerbated after abrupt withdrawal Hypersensitivity to catecholamines has been observed during withdrawal Exacerbation of angina and, in some cases, myocardial infarction (MI) may occur after abrupt discontinuance When long-term beta blocker therapy (particularly with ischemic heart disease) is discontinued, dosage should be gradually reduced over 1-2 weeks with careful monitoring If angina worsens markedly or acute coronary insufficiency develops, beta-blocker administration should be promptly reinitiated, at least temporarily (in addition to other measures appropriate for unstable angina) Patients should be warned against interruption or discontinuance of beta-blocker therapy without physician advice Because coronary artery disease (CAD) is common and may be unrecognized, beta-blocker therapy must be discontinued slowly, even in patients treated only for hypertension Use with caution in cerebrovascular insufficiency, CHF, cardiomegaly, myasthenia gravis, hyperthyroidism or thyrotoxicosis (may mask signs or symptoms), liver disease, renal impairment, peripheral vascular disease, psoriasis (may cause exacerbation of psoriasis) May exacerbate bronchospastic disease; monitor closely Beta blockers can cause myocardial depression and may precipitate heart failure and cardiogenic shock Sudden discontinuance can exacerbate angina and lead to MI and ventricular arrhythmias in patients with CAD Worsening cardiac failure may occur during up-titration of metoprolol succinate; if such symptoms occur, increase diuretics and restore clinical stability before advancing the dose of metoprolol succinate; it may be necessary to lower the dose of metoprolol succinate or temporarily discontinue it Bradycardia, including sinus pause, heart block, and cardiac arrest, has been reported; patients with 1° atrioventricular block, sinus node dysfunction, or conduction disorders may be at increased risk Increased risk of stroke after surgery May potentiate hypoglycemia in patients with diabetes mellitus and may mask signs and symptoms Avoid starting high-dose regimen of extended-release metoprolol in patients undergoing noncardiac surgery; use in patients with cardiovascular risk factors is associated with bradycardia, hypotension, stroke, and death Long-term beta blockers should not be routinely withdrawn before major surgery; however, impaired ability of the heart to respond to reflex adrenergic stimuli may augment risks of general anesthesia and surgical procedures Metoprolol loses beta-receptor selectivity at high doses and in poor metabolizers If drug is administered for tachycardia secondary to pheochromocytoma, it should be given in combination with an alpha blocker (which should be started before metoprolol is started) While taking beta blockers, patients with history of severe anaphylactic reaction to variety of allergens may be more reactive to repeated challenge Extended release tablet should not be withdrawn routinely prior to major surgery Hydrochlorothiazide, can cause an idiosyncratic reaction, resulting in acute transient myopia and acute angle-closure glaucoma, which can lead to permanent vision loss if not treated; discontinue hydrochlorothiazide as rapidly as possible if symptoms occur; prompt medical or surgical treatments may need to be considered if intraocular pressure remains uncontrolled; risk factors for developing acute angle-closure glaucoma may include history of sulfonamide or penicillin allergy Caution in patients with history of psychiatric illness; may cause or exacerbate CNS depression Beta-blockers can precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease There are no adequate and well-controlled studies in pregnant women Limited data on the use of metoprolol in pregnant women Risk to fetus/mother is unknown; because animal reproduction studies are not always predictive of human response, use if clearly needed Bioavailability: 40-50% (immediate-release) ; 65-77% (extended-release) relative to immediate release Onset: 20 min (IV), when infused over 10 min; onset may be immediate, depending on clinical setting; 1-2 hr (PO) Duration: 3-6 hr (PO); duration is dose-related; 24 hr (ER); 5-8 hr (IV) Peak plasma time: 1.5-2 hr (immediate-release); 3.3 hr (extended-release) Therapeutic range: 35-212 ng/m L The above information is provided for general informational and educational purposes only.

Metoprolol is a beta blocker used in the management of hypertension and chronic angina pectoris, or chest pain. The medication may be used alone or in conjunction with other medications. Because obesity and hypertension often occur concomitantly, metoprolol may be part of the treatment regimen. The "International Journal of Obesity" published a study about the effects of a low dose of metoprolol in conjunction with the appetite suppressant medication sibutramine in its Jan. Sibutramine possesses potential side effects of heart palpitations and hypertension, which can affect patient compliance with taking the medication. The purpose of the study was to determine metoprolol's ability to prevent these side effects. The study's conclusion was that not only did the the low dose of metoprolol diminish the side effects of sibutramine, but it also did not negatively effect the study subjects' metabolism. Sheps states that the weight gain usually happens during the first week of metoprolol therapy. The recommended starting dosage of metoprolol tartrate for people with high blood pressure (hypertension) is 100 mg once a day or 50 mg twice a day. After a week or longer, your healthcare provider may increase or decrease your dosage based on the blood pressure response and/or side effects or metoprolol tartrate. Your healthcare provider may also add a diuretic (a "water pill") or another blood pressure medication if your blood pressure is not controlled by metoprolol tartrate alone. Sometimes taking the medication once a day does not adequately control blood pressure for a full 24 hours. This is particularly common at low dosages (such as 100 mg a day). If this occurs, there are two different options -- take metoprolol tartrate twice a day or increase the once-daily dosage. This site does not dispense medical advice or advice of any kind.
