What is dextromethorphan, guaifenesin, and pseudoephedrine (Altarussin CF, Ambifed-G DM, Relacon-DM NR, Robitussin Cold and Cough, Robitussin Pediatric Cough and Decongestant, Suda-Tussin DM, Touro CC, Touro CC-LD, Tussafed-LA)?

Dextromethorphan is a cough suppressant. It affects the signals in the brain that trigger cough reflex.

Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.

Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

The combination of dextromethorphan, guaifenesin, and pseudoephedrine is used to treat stuffy nose, sinus congestion, cough, and chest congestion caused by the common cold or flu.

Dextromethorphan will not treat a cough that is caused by smoking, asthma, or emphysema.

Dextromethorphan, guaifenesin, 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 dextromethorphan, guaifenesin, and pseudoephedrine?

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 cough, cold, allergy, or sleep medication without first asking your doctor or pharmacist. If you take certain products together you may accidentally take too much of one or more types of medicine. Read the label of any other medicine you are using to see if it contains a decongestant, expectorant, or cough suppressant.
