Hydrocodone is a narcotic. It is a pain reliever and a cough suppressant.
Pseudoephedrine 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 pseudoephedrine is used to treat cough and nasal congestion, and to reduce chest congestion caused by the common cold, infections, or allergies.
Guaifenesin, hydrocodone, and pseudoephedrine may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about guaifenesin, hydrocodone, and pseudoephedrine?
Hydrocodone may be habit-forming and should be used only by the person this medicine was prescribed for. Keep the medication in a secure place where others cannot get to it.
Do not use a cough or cold medicine if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Serious, life-threatening side effects can occur if you take cough or cold medicine before the MAO inhibitor has cleared from your body.
Do not use any other over-the-counter cold, allergy, or cough medicine without first asking your doctor or pharmacist. Guaifenesin and pseudoephedrine are contained in many medicines available over the counter. If you take certain products together you may accidentally take too much of a certain drug.
