Drug Overview

MAJOR® Robafen DM is a medication designed to help relieve cough and chest congestion, particularly due to minor throat and bronchial irritation that can occur with a cold. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions, making it easier to drain the bronchial tubes.

This non-drowsy formula is suitable for individuals aged 12 and over and comes in a pleasant raspberry flavor. By controlling cough and relieving chest congestion, MAJOR® Robafen DM aims to provide you with comfort during times of respiratory discomfort.

Uses

In addition to controlling your cough, this medication also helps relieve chest congestion and makes mucus thinner and easier to expel. This can provide you with some much-needed comfort when you're feeling under the weather.
