What is Pseudoephedrine

  • Pseudoephedrine is a decongestant in the nasal passages that shrinks blood vessels. Nasal congestion may result from dilated blood vessels (stuffy nose). Pseudoephedrine is used to relieve nasal and sinus obstruction called the eustachian tubes or congestion of the tubes that drain fluid from the inner ears.

    Pseudoephedrine Uses:

  • Pseudoephedrine is used to temporarily relieve pain/pressure caused by infection or other breathing diseases (such as common cold, flu) in the stuffy nose and sinus (such as hay fever, allergies, bronchitis). This works to reduce swelling and congestion by narrowing the blood vessels. If you are self-treating with this medication, it is important to read the package instructions carefully from the manufacturer so that you know when to consult your doctor or pharmacist. In children younger than 6 years, cough-and-cold products have not been shown to be safe or effective.
  • For use of children younger than 12 years, long-acting tablets/capsules are not recommended. Unless explicitly instructed by a doctor, do not use this pseudoephedrine product in children younger than 12 years of age.
