Thanks for writing in.
400 is a vitamin E supplement
and is not required as such. It is best to take a healthy and balanced diet. Further, too much of vitamin E can damage the body. I would suggest you get a patch test
done to detect the allergen. You can tablet cetrizine
10 mg once daily to prevent these symptoms.
If the allergen is identified, avoiding the allergen would be the main treatment.
Hope this helps.
