Were you looking for information on Guaifenesin? Guafinesin is a common misspelling of guaifenesin.
Guaifenesin, commonly found in products like Mucinex® and Robitussin®, is approved to treat chest congestion. It is often marketed in combination products that include dextromethorphan, a cough suppressant. However, the logic of combining these two drugs has been questioned recently, since the two ingredients have somewhat contradictory effects. Guaifenesin works to thin secretions and make coughing easier and more productive, but dextromethorphan suppresses the cough.
The medication comes in both tablet and syrup forms, and dosing guidelines recommend that it be taken every 4 to 12 hours, depending on the specific product, the condition being treated, and other factors. Guaifenesin can be taken with or without food, but should be taken with plenty of water, since this helps the medicine be more effective.
