Typical dosage for Subsys
Your provider will work with you to prescribe the right dose of Subsys (fentanyl) for your individual needs. It's recommended to use the lowest dose possible for the shortest duration of time to manage your pain.
The typical starting dose is one spray (100 mcg) under your tongue (sublingually) to treat one episode of breakthrough pain. Ask your provider what you should do if your breakthrough pain isn't relieved after you use Subsys (fentanyl).
Wait at least 4 hours before treating another episode of breakthrough pain.
