Mucinex is now the first 600 mg guaifenesin tab available OTC

Mucinex is now the first 600 mg guaifenesin tab available OTC.

This opens the door for Humibid LA, Fenesin, etc to apply for OTC status as well.

Mucinex costs about $20 for 40 tabs. This is about the same as the brand-name Rx products...but much more than the generics.
