## What is Robafen?

Robafen is used to reduce chest congestion caused by the common cold, flu, or chronic bronchitis.

Robafen helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.

There are many brands and forms of guaifenesin available. Not all brands are listed on this leaflet.

Robafen may also be used for purposes not listed in this medication guide.
