In reply to Allergic cross-sensitivity between benzos?, posted by cache-monkey on December 17, 2006, at 23:00:37
> A very troubling thing seems to have happened. I think I've gone allergic to my clonazepam (as a secondary reponse to my super-allergic reaction to Lamictal). I get itchiness and rhinitis that's pretty well correlated in onset with the timing of my Klonopin dose. E.g. if I hold off on the bulk of the dose until night, I don't itch until soon after I take it. It's manageable, but can get pretty annoying, especially as it interferes with my sleep breathing.

I realize that all benzos warn against cross-sensitivity to others in the PI sheet (i.e. don't take this if you've ever had an allergic reaction to other benzos).

That's curious because I've never really heard of benzodiazepines generally being an agent of allergenic reactions.The interfering with breathing at night though does sound concerning, I would definately ask your doctor about that -- I assume you're not on any level that would cause respiratory depression in and of itself. As for cross-pollination, its more tolerance to benzodiazepines than allergies that I know of.
I assume you're not allergic to the dye that is used in the pills because for example tartrazine allergies are not completely uncommon (FD&C Yellow 6), etc.
