Brand Name: Poly Hist NC

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.


Poly Hist NC liquid is used for:

Relieving symptoms of sinus congestion, runny nose, sneezing, itchy nose or throat, itchy or watery eyes, and cough due to colds, upper respiratory infections, or allergies. It may also be used for other conditions as determined by your doctor.

Poly Hist NC liquid is a decongestant, antihistamine, and cough suppressant combination. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing. The cough suppressant works in the brain to help decrease the cough reflex to reduce a dry cough.

Do NOT use Poly Hist NC liquid if:

  • you are allergic to any ingredient in Poly Hist NC liquid or any other codeine- or morphine-related medicine (eg, dihydrocodeine, oxycodone)
  • you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, severe heart problems, or slow or shallow breathing
  • you are unable to urinate or are having an asthma attack
  • you take droxidopa, sodium oxybate (GHB), or 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
