Hi
@Sharon14448,
I wouldn't have thought that anything you sniff would affect your blood sugar, so in that sense I think the choice is yours. But you're the person in charge - surely you can measure your sugar before and after to see any effect? If it's bad, you can avoid that medicine in the future.
To give you an idea, I was in hospital once and my sugar went beyond 30 mmol/l, so much so that a few of their glucometers went off-scale (in general, the glucometers on the wards are exactly the same ones that you or I would use at home). They got very worried and put me on an insulin drip to bring it down, but nothing bad happened to me as a result. I mean, it'd be very scary if you had that kind of blood sugar reading for weeks and months on end (most probably, suicidal), but as a one-off it had no long-term effect on me (in fact, I felt fine throughout). In my case, my sugar was back to "normal" within 12 hours or so.
