chlorpheniramine, methscopolamine, and pseudoephedrine (cont.)

What should I discuss with my healthcare provider before taking chlorpheniramine, methscopolamine, and pseudoephedrine (Coldamine, DryMax, Durahist, Histatab, PCM-LA)?

Do not use this 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.

You should not use this medication if you have severe constipation, a blockage in your stomach or intestines, or if you are unable to urinate.

Do not use this medicine if you have untreated or uncontrolled diseases such as glaucoma, asthma or COPD, high blood pressure, heart disease, coronary artery disease, or a thyroid disorder.

Ask a doctor or pharmacist if it is safe for you to take this medication if you have:

FDA pregnancy category C. It is not known whether chlorpheniramine, methscopolamine, and pseudoephedrine will harm an unborn baby. Do not use this medicine without medical advice if you are pregnant.

Chlorpheniramine, methscopolamine, and pseudoephedrine may pass into breast milk and may harm a nursing baby. Antihistamines and decongestants may also slow breast milk production. Do not use this medicine without medical advice if you are breast-feeding a baby.

How should I take chlorpheniramine, methscopolamine, and pseudoephedrine (Coldamine, DryMax, Durahist, Histatab, PCM-LA)?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. This medicine is usually taken only for a short time until your symptoms clear up.

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.

Do not take for longer than 7 days in a row. Talk with your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache or skin rash.

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.

Do not crush, chew, break, or open an extended-release tablet or capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.

If you need surgery or medical tests, tell the surgeon or doctor ahead of time if you have taken this medicine within the past few days.

Store at room temperature away from moisture and heat. Do not allow the liquid form of this medicine to freeze.
