Pseudoephedrine is an active ingredient in nasal decongestants like SUDAFED®. It helps to clear up congestion and sinus pressure caused by colds, hay fever, or other upper respiratory allergies.
How Pseudoephedrine Works:
Pseudoephedrine brings powerful sinus congestion relief by narrowing swollen tissues and blood vessels in the nose so that air can pass through freely—which results in easier breathing.
How to Buy Pseudoephedrine:
Pseudoephedrine is available at your local pharmacy behind the counter—without a prescription. There is a limit on the quantity that each person can purchase per day and per month as well as a minimum age limit. Talk to your pharmacist if you have questions before purchasing.
