What is the most important information I should know about acetaminophen, dextromethorphan, guaifenesin, and pseudoephedrine?

Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children. Do not use this medication 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. Do not take more of this medication than is recommended. An overdose of acetaminophen can cause damage to your liver. Do not use any other over-the-counter cough, cold, allergy, or pain medication without first asking your doctor or pharmacist. If you take certain products together you may accidentally take too much of a certain drug. Read the label of any other medicine you take to see if it contains acetaminophen, dextromethorphan, guaifenesin, or pseudoephedrine. Avoid drinking alcohol. It can increase the risk of liver damage while you are taking acetaminophen. If you drink more than three alcoholic beverages per day, do not take acetaminophen without your doctor's advice, and never take more than 2 grams (2000 mg) per day. Dextromethorphan will not treat a cough that is caused by smoking.

What is acetaminophen, dextromethorphan, guaifenesin, and pseudoephedrine?

Acetaminophen is a pain reliever and fever reducer.

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 up.

Pseudoephedrine is a decongestant. It constricts (shrinks) blood vessels (veins and arteries). This reduces the blood flow to certain areas, which decreases swelling and allows nasal and respiratory (breathing) passages to open up.

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

Acetaminophen, dextromethorphan, guaifenesin, and pseudoephedrine may also be used for other purposes not listed in this medication guide.
