Excessive Sweating

hi guys
my sis is 15 years old and very active and has problem with Excessive Sweating and its so odourful. even her washed clothes are odourful. she showers daily she is allergic so cant use too much perfume, and antiperspirant deodorant doesnt work as well.

she went to doctor and he gave her Prantal powder to use. but so far its not improved.
now she has started taking it easy and doesnt care about it and i hate it.

anyone with the same problem?. i really need to help her?

Well if your in America you can use a product called Certain Dri, you apply it at night and use deodorant the following morning. It has prescription strength to block perspiration. I found it in the deodorant section of Walmart. Hope that helped.
