Were you looking for information on Guaifenesin? Guafenesin is a common misspelling of guaifenesin.
Many cold and cough products, including Robitussin® and Mucinex®, contain guaifenesin. This medication is an expectorant, which works to thin and loosen phlegm and other bronchial secretions, thereby making them easier to cough up. It comes in tablet and syrup forms, and is typically taken every 4 to 12 hours.
While most people tolerate this medicine well, side effects are possible with guaifenesin, such as headaches, nausea, and dizziness. If you experience kidney stones while taking this drug or signs of an allergic reaction, such as wheezing, swelling, or difficulty breathing, seek immediate medical attention.
