How could i help a sweating problem?

So, i have a hereditary problem, over active underarm sweat glands. i hate it, and i cant wear things when i want to. I do have a prescription medicine i use, but it only works temporarily, and it stings when its working. also, its not fully dependable. i sweat just sitting in clrooms, or even out in the cold. anyone know of anything i can do to help this? :[:[:[:[
