I'm writing about an omission in your article, "Administering a Transdermal Drug" (Clinical Do's and Don'ts, May 2008).* Writing the date and time of application on a label and attaching it to the patch helps other health care providers determine the length of time the patch has been in place. This is especially significant when the patch is to be worn for several days before being changed.
