Pseudoephedrine

Pronunciation

Generic Name: pseudoephedrine (SOO-doe-e-FED-rin)
Brand Name: Examples include Nexafed and Sudafed

Pseudoephedrine is used for:

Relieving nasal congestion due to colds, flu, hay fever, and other allergies. It may also be used for other conditions as determined by your doctor.

Pseudoephedrine is a decongestant. It works by reducing swelling and constricting blood vessels in the nasal passages, allowing you to breathe more easily.

Do NOT use pseudoephedrine if:

  • you are allergic to any ingredient in pseudoephedrine
  • you have severe high blood pressure, severe heart blood vessel disease, a rapid heartbeat, or severe heart problems
  • you are taking droxidopa or 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.

Before using pseudoephedrine:

Some medical conditions may interact with pseudoephedrine. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
