Drug Overview

DECONEX DMX is a combination medication designed to help relieve symptoms associated with the common cold, hay fever (allergic rhinitis), and other upper respiratory allergies. It contains three active ingredients: dextromethorphan HBr (17.5 mg), which acts as a cough suppressant; guaifenesin (400 mg), an expectorant that helps loosen phlegm (mucus) and makes coughs more productive; and phenylephrine HCl (10 mg), a nasal decongestant that reduces swelling in the nasal passages and alleviates nasal congestion.

By temporarily addressing these symptoms, DECONEX DMX can help you feel more comfortable when dealing with respiratory issues, allowing for easier breathing and a more productive cough.

Uses

You can use this medication to temporarily relieve symptoms caused by the common cold, hay fever (allergic rhinitis), or other upper respiratory allergies. It helps ease a cough that results from minor irritation in your throat and bronchial tubes. Additionally, it works to loosen phlegm (mucus) and thin out bronchial secretions, making it easier for you to cough up mucus and clear your airways.

This medication also helps reduce nasal congestion and swelling in your nasal passages, allowing for easier breathing. If you're dealing with any of these symptoms, this product may provide the relief you need.

Dosage and Administration

If you are an adult or a child aged 12 years and older, you can take 1 tablet every 4 hours as needed. However, make sure not to take more than 6 tablets in a 24-hour period. For children between the ages of 6 and under 12, the recommended dose is 1/2 tablet every 4 hours, with a maximum of 3 tablets in a day.
