Cotabflu

Generic Name: chlorpheniramine/codeine/acetaminophen (KLOR-fen-IR-a-meen/KOE-deen/a-SEET-a-MIN-oh-fen)
Brand Name: Cotabflu

Cotabflu contains acetaminophen. Severe and sometimes fatal liver problems, including the need for liver transplant, have been reported with the use of acetaminophen. Most cases of these liver problems occurred in patients taking excessive doses of acetaminophen (more than 4,000 mg per day). Also, patients who developed these liver problems were often using more than 1 medicine that contained acetaminophen. Discuss any questions or concerns with your doctor.

Some children have had serious and sometimes fatal breathing problems when uing codeine after surgery to remove tonsils or adenoids. Talk with your doctor for more information.


Cotabflu is used for:

Treating symptoms of upper respiratory allergies and other conditions, such as cough, runny nose, pain, and fever. Cotabflu may also be used for other conditions as determined by your doctor.

Cotabflu is a narcotic cough suppressant, analgesic, and antihistamine combination. The cough suppressant works in the brain to help decrease the cough reflex. The analgesic works in the brain to reduce pain and fever. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing.

Do NOT use Cotabflu if:

  • you are allergic to any ingredient in Cotabflu
  • you are breast-feeding
  • you have severe or uncontrolled high blood pressure, severe heart blood vessel disease, an enlarged prostate, narrow-angle glaucoma, or a peptic ulcer
  • you are unable to urinate or are having an asthma attack
  • you are taking sodium oxybate (GHB), or if you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days
  • the patient is a child and has just had surgery to remove tonsils or adenoids

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