Robitussin® (guaifenesin)
Use/Effects: Guaifenesin is a commonly prescribed cough syrup that can be purchased over the counter at your local pharmacy. Anecdotally, guaifenesin has been promoted as a cervical mucus thinner. The idea is that guaifenesin can thin cervical mucus, and thereby help sperm travel to the egg for fertilization. There is no clinical evidence that guaifenesin can help you get pregnant, or that all women need thinner cervical mucus. If trying this remedy, make sure that the product you purchase does not contain dextromethorphan, as this ingredient may be harmful to a developing fetus.
