Generic Name: guaifenesin, hydrocodone, and phenylephrine (Pronunciation: gwye FEH neh sin , high droe KOE dohn , and feh nill EH frin)

What is guaifenesin, hydrocodone, and phenylephrine (Levall 5.0, Tussafed-HC, Tussafed-HCG)?

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.

What is the most important information I should know about guaifenesin, hydrocodone, and phenylephrine (Levall 5.0, Tussafed-HC, Tussafed-HCG)?

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 phenylephrine 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.
