"Guaifenesin" is the active ingredient in many cough medicines, such as Robitussin. It is safe to use in pregnancy.
If a pregnant woman has a severe cough that doesn't respond to guaifenesin, her doctor can prescribe codeine and other narcotics. Some prescription cough syrups combine these ingredients.
Your question raises two important points:
1. A pregnant woman needs to be sure that her cough is not from a more serious problem, such as asthma or pneumonia.
2. Information about the safety of medications in pregnancy is often limited.
