About 18 to 24 hours, it should be safe to start a new medication. Here is what the literature says:

To convert patients to another opioid, remove Duragesic and titrate the dose of the new analgesic based upon the patient's report of pain until adequate analgesia has been attained. Upon system removal, 17 hours or more are required for a 50% decrease in serum fentanyl concentrations. Withdrawal symptoms are possible in some patients after conversion or dose adjustment
It would be best if your pain Dr told you how to begin your new medicine because you will be in pain long before the Fentanyl is "out of your system" and as Fentanyl is still absorbed by the skin even 24 hours after removal, he may need to titrate you up on the new med rather than taking a full dose at first.
