  • Helpful in relieving congestion-related headaches.

  • Doesn't give you rebound congestion (worse symptoms when you stop taking it) like nasal spray decongestants do.
  • Available over the counter without a prescription.
  • First-choice medication for treating runny and stuffy noses caused by allergies. It works by reducing inflammation in the nose.
