Dear Barbara,
Much depends upon why you are taking it, how long it has been, and the dose (which you did tell me).
I'm giving you a link to a site that deals with the agent; the page is written for non-professionals.

If you're been on the agent for any considerable period of time, step down is the way to go. Withdrawl can be ferocious, depending upon the nature of the person involved.
Another way is to stop BEFORE using the last patch. Then, if it gets bad, you have something to fall back on while you're getting the 12.5 mg patches.
Good luck.
