Generic Sudafed

Sudafed (pseudoephedrine) is an alpha agonist used to treat nasal congestion and sinus pressure. It works by restricting the blood vessels in the nose and sinuses. Sudafed doesn't require a prescription, but there are restrictions on its purchase and it is only available at the pharmacy counter. Generic pseudoephedrine is available, and Sudafed PE is another over-the-counter alternative with a different active ingredient (phenylephrine) that has no restrictions.
