What is HydroFed (Guaifenesin/Hydrocodone/Phenylephrine)?
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.
Hydrocodone is a narcotic. It is a pain reliever and a cough suppressant.
Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of guaifenesin, hydrocodone, and phenylephrine is used to treat cough and nasal congestion, and to reduce chest congestion caused by the common cold, infections, or allergies.
Guaifenesin, hydrocodone, and phenylephrine may also be used for other purposes not listed in this medication guide.

Drink extra fluids to help loosen the congestion and lubricate your throat while you are taking this medication.
