Overview

Klacid MR 500mg Tablet is a prescription-only medicine (POM) that contains Clarithromycin 500mg (modified-release). It is supplied as a tablet and is dispensed in Malaysia only against a valid prescription issued by a registered doctor.

Under Malaysian rules for prescription medicines, this page carries product, safety and handling information only. Your doctor or pharmacist will explain whether this medicine is suitable for you, the dose you should take, and how long you should take it.

On DoctorOnCall, Klacid MR 500mg Tablet is reviewed by a licensed doctor through an online consultation and dispensed by a registered pharmacist before delivery. Always follow the instructions on your prescription label and the package insert supplied with the product, and do not share this medicine with anyone else.

Directions for Use

Take Klacid MR 500mg Tablet once daily with food. Swallow the tablet whole with a glass of water – do not crush, split, or chew it, as this would disrupt the modified-release mechanism and could cause the medicine to be released too quickly.

Dosage

The usual dose of Klacid MR 500mg Tablet for most infections is one to two tablets (based on the prescribed total daily dose) once daily with food, for a course length determined by your doctor according to the infection being treated. Complete the full course even if you start to feel better.

Storage Instructions

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