What is Novahistine Expectorant (codeine, guaifenesin, and pseudoephedrine)?
Codeine is a narcotic cough suppressant.
Guaifenesin is an expectorant. It helps loosen mucus 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 codeine, guaifenesin, and pseudoephedrine is used to treat stuffy nose and cough, and to reduce chest congestion caused by the common cold, infections, or allergies.
Codeine, 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 Novahistine Expectorant (codeine, 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 or cold 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 guaifenesin or pseudoephedrine. Codeine may be habit-forming and should be used only by the person it was prescribed for. Codeine should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it. 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.
