I would be more than happy to reply to your inquiry... ANY of the nose sprays that are steroid based have a rebound effect and that is why we pulled our daughter off of them, besides the fact that after only a few hours the drip would return, faster and more ferocious than before. This vicious cycle then led to nowhere b/c after a few uses per day, your hands are tied and they cannot and should not be used anymore, even when the problem returns. In other words, they can only be used so much before you're in danger of overdosing them into the nasal passage and that is not a viable answer to allergic rhinitis, a problem that is persistant and annoying!
We couldn't imagine using a Neti Pot on a child, she would not tolerate it so we opted for the all natural sea salt nasal spray which works just as well, if not better. You can find them at any drug store or health store but difficult to find any there without additives of some sort which is still a better option than the drugs. If you buy one and it doesn't seem to be working, just add a little more non-iodized sea salt to it as they tend to be a little weak when store bought.
Hope this helps!
