METOPROL-25 TAB contains Metoprolol 25mg, which is a beta-blocker medication used primarily to treat high blood pressure, chest pain (angina), and certain heart conditions such as heart failure and arrhythmias. It works by blocking the action of certain chemicals in the body, which helps to slow the heart rate, reduce blood pressure, and improve blood flow. Common side effects include dizziness, fatigue, and cold extremities. Less common side effects may include shortness of breath, depression, or sleep disturbances. It is important to take METOPROL-25 TAB as prescribed by your doctor and avoid sudden discontinuation, as this can lead to worsening heart conditions. Patients should not use this medication if they have severe bradycardia (slow heart rate), heart block, or uncontrolled heart failure. Always follow your healthcare provider's instructions and inform them of any other medications you are taking to avoid potential drug interactions.
