    Calculate spray dosing for nasal delivery

    How it works

    Dissolve 10mg in 5ml of solution. With a standard 0.1ml spray, each actuation delivers 200mcg. For a 500mcg dose, use 3 sprays (alternate nostrils).

    How to Verify Your Spray Volume

    Not all nasal spray bottles deliver the same volume per actuation. Before relying on calculated doses, calibrate your specific bottle:

    1. 1.Fill the bottle with plain water and weigh it on a milligram scale (or use a graduated pipette/syringe to measure 1ml precisely).
    2. 2.Prime the pump 3-5 times, then spray 10 actuations into a container.
    3. 3.Collect the sprayed liquid using a 1ml graduated syringe or pipette and measure the total volume.
    4. 4.Divide total volume by 10 to get your actual ml per spray. Enter that value above for accurate dosing.

    Most standard nasal spray bottles deliver between 0.08ml and 0.14ml per actuation. Metered-dose pumps are more consistent than squeeze bottles.

    Nasal Administration Tips

    • 1.Prime the spray bottle with 2-3 pumps before first use
    • 2.Alternate nostrils for each spray to maximize absorption
    • 3.Tilt head slightly forward, aim spray towards outer wall of nostril
    • 4.Wait 30-60 seconds between sprays in the same nostril
    • 5.Avoid sniffing hard after spraying — gentle breath in is sufficient
