I would strongly recommend against using peroxide on your nasal passages.
This is not medical advice. I am not a doctor. I'm just a factory reject with defective genes who has put lots of stuff up my nose over the years, sometimes out of desperation. So I have, in fact, put peroxide up my nose and my personal opinion is that it's a really bad thing to do as it hurts like a bitch and also leaves you defenseless.
