Chlorpheniramine/
hydrocodone liquid

Generic Name: chlorpheniramine/hydrocodone (klor-fen-EER-a-meen/hye-droe-KOE-done)
Brand Name: S-T Forte 2

Chlorpheniramine/hydrocodone liquid is used for:

Treating symptoms of the common cold, flu, or hayfever, and other upper respiratory allergies such as cough, runny nose, sneezing, itching of the nose and throat, and itchy, watery eyes. Chlorpheniramine/hydrocodone liquid may also be used for other conditions as determined by your doctor.

Chlorpheniramine/hydrocodone liquid is a narcotic antitussive (cough suppressant) and antihistamine combination. The antitussive (codeine) works by suppressing the cough center in the brain. The antihistamine (promethazine) works by blocking the action of histamine, which reduces the symptoms of an allergic reaction such as itch, watery eyes and runny nose.

Do NOT use chlorpheniramine/hydrocodone liquid if:

  • you are allergic to any ingredient in chlorpheniramine/hydrocodone liquid or any other codeine-related medicine (eg, codeine)
  • you have diarrhea associated with poisoning, antibiotic use, or a bacterial infection (from eating or drinking contaminated food or water)
  • you are taking sodium oxybate (GHB)

Contact your doctor or health care provider right away if any of these apply to you.

  • Barbiturate anesthetics (eg, thiopental), cimetidine, ketorolac, naltrexone, or sodium oxybate (GHB) because the risk of side effects of chlorpheniramine/hydrocodone liquid, including dangerous sleepiness and a decrease in the ability to breathe, may be increased
