Hello Angela
I might be able to help you in this regard.In 2003, while attending Camp Wonder in northern California, I met the executive director of research and development for Connetics Corporation, Dr. Lincoln Krochmol.Connetics Corporation distributes soriatane in the United States.At that time, he told me the time Soriatane stays in your system changed from 2 years to 3 years. Im not sure if the requirments have changed since that time. Connetics merged with Stiefel Corporation, so they might be the ones to contact.Take care Angela and I hope this helps.
Sincerely,
Les
