Were you looking for information on Guaifenesin? Guafenisin is a common misspelling of guaifenesin.
Cold and cough products like Robitussin® and Mucinex® contain guaifenesin, an expectorant. This drug thins mucus and other bronchial secretions, which makes it easier to cough them up. This, in turn, help relieve chest congestion. Because of this thinning activity, guaifenesin is sometimes recommended to help women become pregnant; however, this is an off-label use.
This medication is not right for everyone. For example, people with certain breathing conditions, such as asthma, COPD, and emphysema, should talk to a healthcare provider before taking it, as should women who are breastfeeding. In addition, if you experience anything that just "does not seem right," stop taking guaifenesin and seek medical attention.
