METLOC XL 12.5

# Metoprolol Tartrate 12.5 mg ## SHORT DESCRIPTION **Metoprolol Tartrate 12.5 mg** is a **beta-1 selective beta-blocker** used to manage several cardiovascular conditions, including **high blood pressure, angina (chest pain), and certain fast or irregular heart rhythms**. It may also be used after a heart attack and for other cardiovascular conditions when prescribed. It works mainly by slowing the heart rate and reducing the force with which the heart pumps, which lowers blood pressure and reduces the heart's demand for oxygen. > **Important:** Metoprolol Tartrate is an **immediate-release formulation**. It is different from extended-release metoprolol formulations, and the dosing schedule should not be interchanged without medical advice. ## KEY BENEFITS * Helps lower high blood pressure * Slows an excessively fast heart rate * Helps reduce the heart's workload * Reduces the heart's oxygen demand * Helps prevent or reduce symptoms of angina * May help control certain abnormal heart rhythms * May be used as part of treatment following a heart attack * Can help reduce cardiovascular strain when appropriately prescribed ## USES / INDICATIONS Metoprolol Tartrate 12.5 mg may be prescribed for: * **Hypertension (high blood pressure)** * **Angina pectoris** * Certain **tachyarrhythmias (fast heart rhythms)** * Heart-rate control in selected patients with atrial fibrillation or other supraventricular arrhythmias * Treatment following **myocardial infarction (heart attack)** * Other cardiovascular conditions when specifically prescribed The approved indications and dosing recommendations may vary depending on the country and product labeling. ## HOW IT WORKS Metoprolol primarily blocks **beta-1 adrenergic receptors** in the heart. This reduces the effects of adrenaline and related stress hormones, resulting in: * Slower heart rate * Reduced force of heart contraction * Reduced blood pressure * Reduced oxygen demand by the heart By slowing electrical conduction through the heart, metoprolol can also help control certain rapid heart rhythms. At usual doses, metoprolol is relatively selective for beta-1 receptors, but this selectivity is **not absolute**, particularly at higher doses. ## DOSAGE & ADMINISTRATION The appropriate dose depends on the condition being treated and the patient's response. * Take Metoprolol Tartrate exactly as prescribed. * Because tartrate is an immediate-release formulation, it is commonly taken **once or several times daily depending on the indication and prescribed regimen**. * Take it at approximately the same time each day. * It may be taken with or immediately after food. * Swallow tablets with water. * Do not change from metoprolol tartrate to metoprolol extended-release products without medical advice. * Do not stop treatment suddenly. ### 12.5 mg dose **12.5 mg may be used as a low starting or adjusted dose in selected patients.** The correct dose varies according to the condition, heart rate, blood pressure, age, and other medical factors. ### Missed dose Take the missed dose when remembered unless it is close to the next scheduled dose. Do not take two doses at the same time. ## SIDE EFFECTS Common side effects may include: * Tiredness or fatigue * Dizziness * Slow heartbeat * Low blood pressure * Cold hands and feet * Headache * Weakness * Nausea * Diarrhea * Sleep disturbances or vivid dreams Some side effects may become less noticeable as the body adjusts to treatment. ### Serious side effects Seek medical attention if you experience: * Very slow or irregular heartbeat * Fainting * Severe dizziness * Shortness of breath or worsening breathing difficulty * Swelling of the legs or sudden weight gain * Severe allergic reaction * Chest pain that is new, severe, or worsening ## PRECAUTIONS & WARNINGS ### Do not stop suddenly Stopping metoprolol abruptly can cause a rapid increase in heart rate and blood pressure and may worsen angina or increase the risk of serious cardiovascular events. The dose should generally be reduced gradually under medical supervision when discontinuation is required. ### Low heart rate Metoprolol can slow the heart rate. Tell your doctor if you have a naturally slow pulse or a history of heart conduction problems. ### Low blood pressure Metoprolol may cause dizziness or fainting due to reduced blood pressure, particularly when starting treatment or increasing the dose. ### Asthma and breathing disorders Although metoprolol is relatively beta-1 selective, it can affect beta-2 receptors at higher concentrations. Use caution if you have **asthma, COPD, or other breathing disorders**. ### Diabetes Beta-blockers can mask some warning symptoms of low blood sugar, particularly a rapid heartbeat. People with diabetes should monitor blood glucose carefully. ### Heart failure Metoprolol may be used in selected heart-failure patients, but the appropriate formulation and dosing are important. Starting or increasing treatment requires medical supervision. ### Peripheral circulation problems Metoprolol may worsen symptoms of poor circulation in some people. ### Thyroid disorders Metoprolol may mask some symptoms of hyperthyroidism, such as a rapid heartbeat. ### Surgery and anesthesia Tell your doctor or anesthetist that you are taking metoprolol before surgery. ## DRUG INTERACTIONS Metoprolol can interact with several medicines. Important interactions include: * **Other medicines that lower heart rate or blood pressure** — may cause excessive slowing of the heart or low blood pressure. * **Verapamil and diltiazem** — may significantly slow heart rate or cardiac conduction. * **Digoxin** — can increase the risk of bradycardia and conduction problems. * **Clonidine** — requires careful management because of effects on blood pressure and heart rate. * **Insulin and oral diabetes medicines** — beta-blockers may mask certain symptoms of hypoglycemia. * **Certain antidepressants**, including medicines that inhibit CYP2D6, may increase metoprolol levels. * **Other beta-blockers** — may produce excessive beta-blockade. * **Certain antiarrhythmic medicines** — may increase the risk of slow heart rate or conduction abnormalities. Tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and herbal supplements you use. ## STORAGE INFORMATION * Store Metoprolol Tartrate 12.5 mg according to the manufacturer's instructions. * Keep at room temperature. * Protect from excessive heat, moisture, and direct sunlight. * Keep tablets in their original packaging. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or the medicine appears abnormal. ## PRESCRIPTION STATUS **Metoprolol Tartrate 12.5 mg is generally a prescription medicine.** Because it affects heart rate and blood pressure, treatment should be initiated and adjusted under the supervision of a qualified healthcare professional. ## GENUINE MEDICINE ASSURANCE To help ensure you receive genuine Metoprolol Tartrate 12.5 mg: * Purchase only from a licensed and reputable pharmacy. * Check the medicine name and **12.5 mg strength**. * Confirm that the formulation is **metoprolol tartrate**, not an extended-release formulation unless specifically prescribed. * Check the manufacturer and product information. * Verify the batch number and expiry date. * Ensure the packaging is sealed and undamaged. * Avoid medicines with suspicious or altered packaging. * Consult a pharmacist if you have concerns about authenticity. ## FAQ SECTION ### What is Metoprolol Tartrate 12.5 mg used for?
