Frequently asked questions

What does Mucinex treat?
Mucinex (Guaifenesin) may be used to treat bronchitis, common cold, cough, laryngitis, pharyngitis, perennial allergic rhinitis, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label).

How much does Mucinex cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.07 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
