Reasons not to take this medicine

• If you have an allergy to chlorpheniramine, phenylephrine, dextromethorphan, or any other part of this medicine.

• Tell healthcare provider if you are allergic to any medicine. Make sure to tell about the allergy and how it affected you. This includes telling about rash; hives; itching; shortness of breath; wheezing; cough; swelling of face, lips, tongue, or throat; or any other symptoms involved.

• If you have any of the following conditions: Glaucoma, severe heart disease, trouble urinating, ulcer disease, or uncontrolled high blood pressure.

• If you have taken isocarboxazid, phenelzine, or tranylcypromine in the last 14 days. Monoamine oxidase inhibitors (eg, isocarboxazid, phenelzine, and tranylcypromine) must be stopped 14 days before this medicine is started. Taking the two together could cause dangerously high blood pressure.

How does it work?
