Beconase symptoms and conditions

Im 36 , my pneumologo put me on a treatment for 30 days Zyrtec D and Singular on day 6 w quit Zyrtec provoque me and arrithmia, the 3 days later quit Singulair, sence of more dryness and irregular arrithmia. Go to the original I was before just Clarinex and I felt very bad take a spray shot of Beconase

I used nasonex for a month feb 2006 and experienced terrible insomnia and palpatations at night and i also had optic neuritis in my left eye. Is the ON to do with tiredness from not sleeping. All stopped once nasonex stopped. Taken beconase since, however i have had a sinus infection and optic neuritis again april 2007. Is there a relationship between corticosteroids and optic neurits?
