chlorpheniramine, codeine, and pseudoephedrine (cont.)

What should I discuss with my healthcare provider before taking chlorpheniramine, codeine, and pseudoephedrine (Phenylhistine DH Expectorant)?

Do not use this medication if you are allergic to codeine or other narcotic medicines such as fentanyl (Actiq, Duragesic), hydromorphone (Dilaudid, Palladone), methadone (Methadose, Dolophine), morphine (Kadian, MS Contin, Oramorph, and others), oxycodone (Oxycontin), and oxymorphone (Opana).

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. A dangerous drug interaction could occur, leading to serious side effects.

To make sure you can safely take chlorpheniramine, codeine, and pseudoephedrine, tell your doctor if you have any of these other conditions:

It is not known whether this medication will harm an unborn baby. Codeine may cause addiction or withdrawal symptoms in a newborn if the mother takes the medication during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using chlorpheniramine, codeine, and pseudoephedrine.

Codeine can pass into breast milk and may harm a nursing baby. The use of codeine by some nursing mothers may lead to life-threatening side effects in the baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Codeine may be habit forming and should be used only by the person it was prescribed for. Never share this medication with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

How should I take chlorpheniramine, codeine, and pseudoephedrine (Phenylhistine DH Expectorant)?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Cough or cold medicine is usually taken for only a short time until your symptoms clear up.

Do not give this medication to a child younger than 4 years old. 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.

Measure liquid medicine with a special dose measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose measuring device, ask your pharmacist for one.

Talk with your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache, cough, or skin rash.

If you need surgery, tell the surgeon ahead of time if you have taken a cough or cold medicine within the past few days.

This medication can cause unusual results with allergy skin tests. Tell any doctor who treats you that you are taking an antihistamine.

Store at room temperature, away from heat, light, and moisture.

Keep track of the amount of medicine used from each new bottle. Codeine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
