Typical dosage for Flunisolide

Each spray contains 25 mcg of flunisolide.

  • Adults and children 15 years and older: The typical starting dose is 2 sprays in each nostril twice a day. Your primary care provider might raise the dose to 2 sprays in each nostril three times a day if you need more relief. Don't use more than 8 sprays in each nostril in a day.
  • Children age 6 to 14 years old: The typical starting dose is 1 spray in each nostril three times a day. Another option is 2 sprays in each nostril twice a day. Don't use more than 4 sprays in each nostril in a day.

Once your allergy symptoms get better, your prescriber will typically lower the dose to the smallest amount needed to keep your symptoms at bay. Some people might only need 1 spray in each nostril per day as a maintenance dose.
