Pro-Red AC syrup

Generic Name: codeine/phenylephrine/pyrilamine (KOE-deen/fen-ill-EF-rin/peer-IL-a-meen)
Brand Name: Examples include Pro-Red AC and Zotex-C

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


Pro-Red AC syrup is used for:

Treating symptoms of the common cold, flu, or hay fever, and other upper respiratory allergies such as cough, congestion, runny nose, sneezing, itching of the nose and throat, and itchy, watery eyes. Pro-Red AC syrup may also be used for other conditions as determined by your doctor.

Pro-Red AC syrup is a narcotic antitussive (cough suppressant), antihistamine, and decongestant combination. The antitussive works by suppressing the cough center in the brain. The antihistamine works by blocking the action of histamine, which reduces the symptoms of an allergic reaction such as itch, watery eyes and runny nose. The decongestant shrinks swollen nasal passages, which relieves nasal congestion.

Do NOT use Pro-Red AC syrup if:

  • you are allergic to any ingredient in Pro-Red AC syrup or any other codeine-related medicine (eg, dihydrocodeine)
  • you have diarrhea associated with poisoning, antibiotic use, or a bacterial infection (from eating or drinking contaminated food or water)
  • you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, or severe heart problems
  • you are taking sodium oxybate (GHB) or if you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (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.
