Usually Ur doc can give u a list of safe things to take. Reg robitussin DM with the least amount of alcohol but check with your provider first
I take adult robitussin DM when pregnant. Both last pregnancy and this one also. My Dr allows that. I don't think it's necessary to take children's.
Adult Robitussin DM is fine.
