Fentanyl Sandoz patches are used to relieve very strong and long-lasting pain in adults and children over 2 years old who are already taking opioid medicines.
Your doctor will decide the right strength for you. Do not change the dose on your own.
Apply one patch to a flat area of your upper body or arm (for adults), or upper back (for children). Replace the patch every 3 days (72 hours) at the same time of day. Always remove the old patch before applying a new one.
Use only one patch at a time, replacing it every 3 days. Do not exceed the prescribed dose or wear multiple patches simultaneously.
