Drug Overview

Guaifenesin Extended-Release Tablets contain 600 mg of guaifenesin, a medication designed to help you manage coughs caused by colds or other respiratory conditions. It works by loosening phlegm (mucus) and thinning bronchial secretions, which helps clear out mucus from your airways, making your coughs more productive.

This means that when you take guaifenesin, it can assist in relieving congestion and making it easier for you to breathe by clearing out the mucus that can build up in your lungs and throat.

Uses

If you're dealing with a cough that produces mucus, this medication can help. It works by loosening phlegm (a type of mucus) and thinning out bronchial secretions. This action makes it easier for you to clear out the mucus from your airways, leading to more productive coughs. By helping to rid your bronchial passageways of bothersome mucus, it can make breathing feel more comfortable.
