Uses & Benefits
High blood pressure (hypertension), Angina (chest pain), Heart failure (as add-on/maintenance therapy as prescribed), Control of heart rate in tachyarrhythmias, Prevention of migraine (prophylaxis) as advised by doctor
How It Works
Metoprolol is a selective beta-1 blocker that reduces the effect of adrenaline on the heart. It slows heart rate and decreases the force of contraction, lowering blood pressure and reducing the heart’s oxygen demand.
Directions for Use
Take exactly as prescribed, usually once daily for prolonged-release tablets. Swallow whole with water; do not crush or chew. Can be taken with or without food, preferably at the same time each day. Do not stop suddenly without medical advice.
Side Effects
Tiredness, dizziness, slow heart rate (bradycardia), low blood pressure, cold hands/feet, headache, nausea, sleep disturbances
Warnings & Precautions
Do not stop abruptly (risk of rebound angina/raised BP). Use with caution in asthma/COPD, diabetes (may mask hypoglycaemia symptoms), thyroid disorders, peripheral vascular disease, low heart rate, heart block, severe hypotension, and severe heart failure unless supervised. Monitor pulse and BP regularly. May cause dizziness—avoid driving if affected.
Drug Interactions
Verapamil, diltiazem, digoxin, amiodarone and other antiarrhythmics (risk of bradycardia/heart block), other antihypertensives (additive BP lowering), clonidine (withdrawal interaction), insulin/oral antidiabetics (masks hypoglycaemia), NSAIDs (may reduce BP control), CYP2D6 inhibitors like fluoxetine/paroxetine/quinidine (increase metoprolol levels)
