Maxichlor PSE DM

Generic Name: pseudoephedrine/chlorpheniramine/dextromethorphan (SOO-doe-e-FED-rin/KLOR-fen-IR-a-meen/DEX-troe-meth-OR-fan)
Brand Name: Maxichlor PSE DM

Maxichlor PSE DM is used for:

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

Maxichlor PSE DM 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.

  • you are allergic to any ingredient in Maxichlor PSE DM
  • you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, severe heart problems, stomach ulcer, or narrow-angle glaucoma
  • you are unable to urinate or are having an asthma attack
  • you are taking droxidopa or sodium oxybate (GHB), or you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days

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