I'm inclined to think it's more likely the symptoms of the cold or possibly even an inner ear infection as well. I've had H2O2 put into my ears since being a small child, although generally for wax build-up, and never experienced dizziness or biliousness. I've also suffered vertigo from a middle ear infection and your symptoms mirror that problem.Replied By Kiti (San Diego, CA) on 12/29/2008
I did that one day and i had a violent dizzy spell it scared me so much but mainly it's the temperature of the peroxide. If you put anything in your ear that is room temperature it is still colder than the temperature in your ear so it causes the dizzy spell you need to warm up the bottle in warm-hot water filled sink before doing that.Replied By Lisa (California) on 10/13/2015
The same happened to me. I tried H2O2 in the ears and the next morning woke up to some distressing vertigo. Room would spin every time I lay on my side. I swabbed my ear out the evening after and it got better. Since I've had many colds in my life, and this is the first time trying hydrogen peroxide in the ears, I'm inclined to think it's the hydrogen peroxide that caused the vertigo. It may have something to do with the temperature of the fluid, as another poster suggested.Replied By Simone (Florida) on 01/19/2016
I think everyone who has had a problem with dizzy is because they didn't lay down when they did this. The inner ear helps your balance, thats why you feel dizzy.
