Pump sizes vary. Check what yours is rated for, and prime it before the first dose. Sprays split between nostrils count the same.
How do I know my pump size?
It's printed on the listing or the box, usually 0.1 mL per spray. If you can't find it, count how many sprays empty a known amount of water.
What's the math?
Each spray = bottle mg ÷ bottle mL × pump mL. Sprays per dose = dose ÷ each spray, rounded to a whole spray.
Why doesn't my dose come out exact?
You can't do half a spray. If the nearest whole spray is far off, change how much liquid you mix in.
