Medications and Drugs

Brand Names: Vanacof CD

Generic Name: codeine, dexchlorpheniramine, and phenylephrine (Pronunciation: KOE deen, DEX klor fen IR a meen, FEN il EFF rin)

What is codeine, dexchlorpheniramine, and phenylephrine (Vanacof CD)?

Codeine is in a group of drugs called narcotics. It is a cough suppressant that affects the signals in the brain that trigger cough reflex.

Dexchlorpheniramine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

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

The combination of codeine, dexchlorpheniramine, and phenylephrine is used to treat cough, runny or stuffy nose, and sneezing caused by the common cold.

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

Codeine, dexchlorpheniramine, and phenylephrine may also be used for purposes other than those listed in this medication guide.

What is the most important information I should know about codeine, dexchlorpheniramine, and phenylephrine (Vanacof CD)?

Do not take 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. Serious, life-threatening side effects can occur if you take cough or cold medicine before the MAO inhibitor has cleared from your body.

Read the label of any other medicine you are using to see if it contains dexchlorpheniramine or phenylephrine.

Codeine may be habit-forming and should be used only by the person it was prescribed for. This medication 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.
