Yes it was a patch and sorry I dont remember the name. I also thought since it's not going through my digestive system it would be okay but apparantly with me it didn't make a difference. The symptoms are gas, cramping pains, diahhrea with every single food or beverage. But then everyone is different so it may be different for you. I don't want to discourage anyone from trying anything but just want to let all of you know that it made me worse, so that is something to consider when you are trying to figure out what is wrong and the doctor hasn't a clue.
