What is mucus congestion and how does SUDAFED® treat nasal mucus congestion?

Mucus is naturally produced in our nasal passages to keep them moist and trap dirt and particles. However, when the passage lining becomes inflamed because of an infection or allergy, excess mucus may be produced, blocking the nose, causing pressure and possibly pain. The nasal decongestants in SUDAFED® products work to reduce the inflammation and excess production of mucus, helping relieve the symptoms of congestion.

Is there a SUDAFED® product to treat a blocked nose?

Yes. We’ve specially developed the following products to treat blocked noses: Non-Drowsy SUDAFED® Decongestant Tablets, SUDAFED® Nasal Spray Solution, and Non-Drowsy SUDAFED® Decongestant Syrup. However, all SUDAFED® products may be used to treat blocked noses in conjunction with other symptoms.

Is there a SUDAFED® product to treat sinuses?

Yes. We’ve specially developed the following to target sinus pressure and pain: Non-Drowsy SUDAPLUS® Tablets.
