When contrasted with other propanediol drugs used for this purpose, guaifenesin causes less destruction of red blood cells and is more soluble in water. Guaifenesin comes as a regular and extended-release (long-acting) tablet and capsule and liquid to take by mouth. Guaifenesin comes alone and in combination with antihistamines, cough suppressants, and decongestants. It is sold as pills or syrups under many brand names and is also included in many over-the-counter cough and cold remedies. Guaifenesin is frequently combined with dextromethorphan, an antitussive.
Under normal circumstances this combination leads to fewer, but more productive coughs. It relieves the coughs of colds, bronchitis, and other lung infections. Guaifenesin was chosen for the experimental guaifenesin protocol in the 1990s as a treatment for fibromyalgia, and proponents of the guaifenesin protocol believe that it cures fybromyalgia by removing excess phosphate from the body. A lesser publicized and thus lesser known fact among fibromyalgia sufferers is that guaifenesin has a skeletal muscle relaxant property, and a form of guaifenesin known as guafenesin carbomate is used for this purpose. This may explain some of the symptomatic relief experienced by fibromyalgia sufferers who take guaifenesin. Guaifenesin also has other known neurological effects, including an analgesic effect that is related to its action as a skeletal muscle relaxant, and it may inhibit platelet aggregation.
Directions Do not break, crush, or chew extended-release tablets and do not open extended-release capsules: swallow them whole.

Water consumption is important, not only to help prevent dry mouth, but also to improve the effectiveness of the drug.
