How can I order a complete Betadine Douche kit?

You should be able to order that online and they sell medicated douches at all drug stores and mass merchandise stores. Some stores have their own brand of Iodine called Povidine. You can buy the regular Betadine and make your own by adding to regular fragance douche. I wouldn't add it to a vinegar and water or one with baking soda though. Just use the scented kind and check to make sure it doesn't have vinegar or baking soda.
