What is Robitussin for adults?

Robitussin is a brand name for a range of cough and cold medicines that contain different active ingredients. One of the most common products is Robitussin DM, which combines an expectorant (guaifenesin) and a cough suppressant (dextromethorphan).

Robitussin DM is used to relieve chest congestion, mucus, and cough caused by the common cold, infections, or allergies. It works by thinning and loosening the mucus in your airways, making it easier to cough out. It also blocks the cough reflex in your brain, reducing the urge to cough.

These are usually mild and temporary, but if they persist or worsen, you should contact your doctor.

Robitussin DM may also interact with some other medicines, such as antidepressants, antihistamines, or pain relievers. You should tell your doctor about all the medicines you are taking before using Robitussin DM.
