my allergies are being controled with lortidine, what is it?

i have had allergies all my life living in very high allergic zones. when i was in my teens i became addicted to nasal sprays. this was during the 1970's. what was the addictive ingredient? i was able to overcome this, cold turkey, one nostril at a time. now once again, i live in an agricultural local. at first i lost my voice for years until nasal inhibitures became available. then i realized i was allergic to dogs. now in order breath and function i am on lortidine 24/7. i have used this in the past but the fillers tended to irritate my digestive system. what is lortidine, is it addictive, what long term affects will it have, and what drugs, etc. are incompatible.
