Overview

Betaloc 50mg Tablet contains Metoprolol tartrate 50mg and is available as a tablet. It is classified as a prescription medicine and may only be obtained with a valid prescription from a registered medical practitioner.

Only product, safety and handling information is published here. Anything beyond that is explained to you directly by your doctor or pharmacist as part of your consultation.

DoctorOnCall is a licensed online pharmacy. Orders for Betaloc 50mg Tablet are processed only after a doctor has assessed your suitability and issued a prescription, and every order is checked by a registered pharmacist before it is sent out.

Directions for Use

Take Betaloc 50mg Tablet at the same times each day, with or without food, and swallow the tablet whole with water. Do not stop taking this medicine suddenly, even if you feel well, as abruptly stopping a beta-blocker can cause a rebound rise in blood pressure, worsening angina, or heart rhythm problems – any dose reduction must be done gradually under your doctor’s guidance.

Dosage

The usual starting dose of Betaloc 50mg Tablet for hypertension or angina is 50-100mg daily, taken in one or two divided doses, which your doctor may adjust based on your heart rate and blood pressure response, typically up to a maximum of 400mg daily. Dosing after a heart attack is individualised and started cautiously in hospital. Always take exactly as prescribed by your doctor.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Contraindications

Drug / Food Interactions

  • Verapamil or diltiazem may cause severe bradycardia or heart block when combined with metoprolol
  • Clonidine withdrawal while on metoprolol may cause a severe rebound rise in blood pressure
  • Insulin or oral diabetes medicines – metoprolol may mask warning signs of low blood sugar such as a fast heartbeat
  • NSAIDs may reduce the blood-pressure-lowering effect of metoprolol

Quick Tips

  • Never stop this medicine abruptly – any change must be guided by your doctor
  • Check your pulse and blood pressure periodically as advised
  • If you have diabetes, monitor your blood sugar closely as symptoms of hypoglycaemia may be masked
