Were you looking for information on Guaifenesin? Guafenisen is a common misspelling of guaifenesin.
The nonprescription medicine guaifenesin is approved for the treatment of chest congestion, but healthcare providers sometimes recommend it for off-label purposes, such as to treat fibromyalgia or to help a woman become pregnant. As an expectorant, the drug works by thinning mucus and other bronchial secretions, which makes coughs more productive.
Most people do not have any problems when taking guaifenesin; however, side effects are possible, such as drowsiness, dizziness, nausea, and headaches. Potentially serious reactions could also occur, such as kidney stones or an allergic reaction. If you experience anything that just "does not seem right" while taking this medicine, contact your healthcare provider.
