What medication can I take for a common cold if I am pregnant?

NONE if possible. A common cold really does not need any treatment--just time. But if you are really misearble then tylenol (acetaminophen) is the first line otc medicine then maybe a cough medicine (plain robitussin). It is recommended to just 'target a symptom' and not take a mixture of drugs (e.g. Nyquil, dayquil, contac....).
