A long-term treatment for allergies, Nasonex does not provide immediate relief.
If you suffer from hay fever, you should begin taking it 2 to 4 weeks before the start of pollen season.
It contains a steroid medication that fights inflammation.
Nasonex nasal spray prevents and relieves the runny, stuffy nose that accompanies hay fever and year-round allergies.
To be effective, it must be prescribed regularly once a day. It starts working within 2 days after the first dose, but takes 1 to 2 weeks to yield its maximum benefits.
