I was given the generic form of Climara and it is a rather thick pink patch; I think the true name brand is clear. I also read somwhere that Climara is made from a soy source and vivelle is made from yams. If you have allergies to either one of those items, you will want to avoid that specific patch.
When I see my doc, I plan to ask to be switched to the vivelle dot; I think it is smaller in size and there are alot of dosing options. It sounds like you have a good doc who is letting you control what form you want. That's pretty impressive! Will you be using any progesterone?
Good luck to you!
