Chlorpheniramine suspension

Pronunciation

Generic Name: chlorpheniramine (KLOR-fen-IR-a-meen)
Brand Name: Examples include Pediox-S and Ricobid H

Chlorpheniramine suspension is used for:

Relieving symptoms of sinus congestion, sinus pressure, runny nose, watery eyes, itching of the nose and throat, and sneezing due to upper respiratory infections (eg, colds), allergies, and hay fever. It may also be used for other conditions as determined by your doctor.

Chlorpheniramine suspension is an antihistamine. It works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing.

Do NOT use chlorpheniramine suspension if:

  • you are allergic to any ingredient in chlorpheniramine suspension
  • you are taking 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.
