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

Ibuprofen is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Ibuprofen works by reducing hormones that cause inflammation and pain in the body.

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

The combination of chlorpheniramine, ibuprofen, and pseudoephedrine is used to treat sneezing, itching, watery eyes, runny nose, stuffy nose, sinus congestion, cough, and pain or fever caused by the common cold or flu.

Chlorpheniramine, ibuprofen, and pseudoephedrine may also be used for purposes other than those listed in this medication guide.

Seek emergency medical attention if you think you have used too much of this medicine. Symptoms of an overdose may include nausea, vomiting, stomach pain, dizziness, feeling restless or nervous, blurred vision, sweating, breathing problems, or seizure (convulsions).

Since cold medicine is usually taken only as needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.
