Drug Overview

Robitussin is a medication designed to provide fast and effective relief from cough and chest congestion. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to temporarily relieve cough caused by minor throat and bronchial irritation, and guaifenesin, an expectorant that helps loosen phlegm (mucus) and thin bronchial secretions, making it easier to drain your bronchial tubes.

This product is suitable for individuals aged 12 and over and is specifically formulated to control cough and relieve chest congestion, helping you feel more comfortable when dealing with cold symptoms.

Uses

If you're dealing with a cough caused by minor irritation in your throat or bronchial tubes, especially during a cold, this medication can provide temporary relief. It works by soothing your throat and helping to ease the discomfort associated with coughing.

Additionally, this medication helps to loosen phlegm (mucus) and thin out bronchial secretions, making it easier for your body to drain the bronchial tubes. This can be particularly helpful when you're feeling congested and need to clear your airways.

Dosage and Administration

When using this medication, it's important to follow the dosing instructions carefully. For adults and children aged 12 years and older, you should take 20 ml every 4 hours, but make sure not to exceed 6 doses in a 24-hour period.
