Can you take Mucinex With Robitussin?

Answer

Mucinex (guaifenesin) can safely be taken with Robitussin (dextromethorphan) and there is no interaction between the two medications. However, Robitussin is a brand name that is used for a variety of products, all of which contain different ingredients. It is important to look at the drug label of the product you are taking to confirm the ingredients.

Taking Mucinex With Robitussin
