Hydrogen peroxide can cause burning, irritation, gas formation due to caustic effect.
You need to reduce the effect by diluting it.
You can continue to take water.
Nexium or zantac can be taken too.
If you feel burning of stomach, throat or if you have vomiting with blood in it, you need to get an examination in hospital.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
