Drug Overview

DM MAX is a maximum strength medication designed to help relieve congestion and cough. 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 your bronchial tubes.

This product is intended for adults and individuals aged 12 and over, providing temporary relief from cough caused by minor throat and bronchial irritation. If you're dealing with congestion and a persistent cough, DM MAX may be a helpful option to consider.

Uses

This medication is designed to help you breathe easier by loosening phlegm (mucus) and thinning bronchial secretions, making it easier for your body to drain the bronchial tubes. If you're experiencing a cough due to minor irritation in your throat or bronchial area, this medication can provide temporary relief from those symptoms.

It's important to note that there are no reported teratogenic effects (which means it doesn't cause birth defects) or nonteratogenic effects associated with this medication. This makes it a safer option for those concerned about potential risks.

Dosage and Administration

It's important to follow the recommended directions when taking this medication. You should use the provided dosage cup to measure your dose accurately. Remember, 1 mL is equal to one milliliter. Make sure not to exceed 6 doses within a 24-hour period to avoid any potential risks.

For adults and children aged 12 years and older, the recommended dose is 20 mL every 4 hours as needed. However, if you have a child under 12 years of age, this medication is not suitable for them, and you should not use it.
