What is acetaminophen, dextromethorphan, and pseudoephedrine (Alka-Seltzer Plus Flu Liquigels, Comtrex Non-Drowsy, DayQuil, Dayquil Liquicaps, Daytime Cold, Non-Drowsy Daytime, Robitussin Honey Flu Non-Drowsy, Theraflu (pseudoephedrine) Daytime Severe Cold, Theraflu Severe Cold & Congestion Non-Drowsy, Triaminic Cough & Sore Throat (pseudoephedrine), Triaminic Softchew Throat Pain and Cough, Triaminic Softchews Cough & Sore Throat (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.

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, and pseudoephedrine is used to treat stuffy nose, sinus congestion, cough, and pain or fever caused by the common cold or flu.

Dextromethorphan will not treat a cough that is caused by smoking.

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

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

Do not give this medication to a child younger than 4 years old. Always ask a doctor before giving cough or cold medicine to a child. Death can occur from the misuse of cough or cold medicine in very young children.

Do not use a cough or cold medicine if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days.

Do not take this medication without a doctor's advice if you have ever had alcoholic liver disease (cirrhosis) or if you drink more than 3 alcoholic beverages per day. You may not be able to take acetaminophen.

Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen.

Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.
