METOPROL-50 TAB contains Metoprolol 50 mg, a beta-blocker used to treat high blood pressure, chest pain (angina), and heart failure. It works by blocking certain chemicals in the body, which helps reduce the workload on the heart and lowers blood pressure. Additionally, it is used to prevent heart attacks and manage arrhythmias (irregular heartbeats). METOPROL-50 TAB is typically taken once daily and should be used under the guidance of a healthcare professional. Common side effects may include dizziness, fatigue, slow heart rate, and cold hands or feet. Less common side effects may include shortness of breath or swelling. It is important to follow your doctor's instructions regarding dosage and not to stop the medication abruptly. If you have a history of asthma, heart conditions, or are pregnant or breastfeeding, consult your doctor before using this medication.
