Is there any harm in taking medication this way?

I have rhinitis which is like an allergy that causes me to have a blocked/runny nose every day of the year and nasal polyps too if not controlled. Although I've had skin and blood allergy tests and they were negative so I don't know what triggers/causes it. Antihistamines help though so I'm assuming it is an allergy.

Anyway I also take a steroid nasal spray (nasonex -mometasone) daily and some nasal drops (fluticasone) when symptoms feel bad/it feels blocked. I've found that the nasonex didn't help all that much and that I was still getting the blocked feeling. However rather than spraying nasonex up my nose I started to spray the substance into a small cap, lie so my nose is upside down and then tip it into my nose. I found that the med really gets into my sinuses this way and my nose has felt less blocked. I was wondering Is there any harm in using it as drops rather than a spray though? I can't see why there would be but then surely if my method was best then the medical profession would have directed us to use it as a drop rather than spray.. That's why I'm wondering is it ok for me to take it like this I definately every day of the year?

If they ve prescribed them to you with those instructions and it's not working well enough why not ask for a alternative instead?

I've tried other things (avamys etc) I was told that nasonex was the best for my symptoms as its intended for nasal polyps too.
