Treatment for thrush depends on if it is in adults or if it is babies and children. You can usually treat it with getting medication like nystatin liquid.

Whenever you get medication normally you would put it on the area of the white patch depending on what kind of medication is being used for treatment.

Babies need treatment and get it by having a cream or either with getting a special ointment or medication. Sometimes babies get a rash and have to be treated for that rash and that usually occurs where the diapher goes.

You should not try and do the treatment yourself without clarification from your doctor. The reason why is because your doctor will need to know and make sure that the treatment you are doing is the right one because it will vary depending on the level that it is.
