Max HC liquid
Generic Name: carbinoxamine/hydrocodone/phenylephrine (car-bihn-OCKS-ah-meen/hye-droe-KOE-done/fen-il-EF-rin)
Brand Name: Examples include Excof-SF and Max HC
Max HC liquid is used for:
Relieving symptoms of sinus congestion, runny nose, sneezing, and cough due to colds, upper respiratory tract infections, and allergies. It may also be used for other conditions as determined by your doctor.
Max HC liquid is a decongestant, antihistamine, and narcotic 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, which reduces a dry cough.

- you are allergic to any ingredient in Max HC liquid or any other codeine- or morphine-related medicine (eg, oxycodone)
- you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, or severe heart problems
- you are unable to urinate or are having an asthma attack
- you have diarrhea due to antibiotic use or poisoning
- you are taking sodium oxybate (GHB), droxidopa, or you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (eg, phenelzine) within the last 14 days
