What should I discuss with my health care provider before taking chlophedianol, guaifenesin, and pseudoephedrine (Vanacof DX)?

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.

• severe coronary artery disease;
• ischemic heart disease (reduced circulation of blood to the heart);
• glaucoma;
• stomach ulcer; or
• if you are unable to urinate;
• if you are having an asthma attack; or
• if you are breast-feeding a baby.

Before using this medication, tell your doctor if you are allergic to any drugs, or if you have:

• heart disease or high blood pressure;
• diabetes;
• asthma, emphysema, chronic bronchitis, or other breathing problems;
• a thyroid disorder;
• an enlarged prostate; or
• urination problems.
