ProHealth's Guaifenesin uses the only FDA approved extended release guaifenesin formula for quick and lasting respiratory therapy. This patented dual action guaifenesin tablet includes an immediate release layer for rapid onset action and an extended release layer that last a full 12 hours. Guaifenesin helps loosen phlegm (mucus) and thins bronchial secretions to rid the respiratory passageways of bothersome mucus while making coughs more productive.

What is Guaifenesin?
Guaifenesin is a common component of many cold and cough remedies that helps loosen and liquefy mucus. Guaifenesin is a safe medication that may even be used by children over 12 years of age. Derived from a tree bark extract called guaiacum, guaifenesin was first used during the 16th century. Twenty years ago, the extract was synthesized, pressed into tablets and named guaifenesin.

FDA Approved Time Release Guaifenesin Tablets
ProHealth's Guiafenesin 600 is the only FDA approved, prescription strength time released guaifenesin formula. This two layered tablet provides a quick release, rapid action dose of guaifenesin, while the exclusive time release layer releases a continued level of guaifenesin into the body that lasts a full 12 hours.
