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 strong opioid pain medication.
Apply one patch; your doctor will tell you the correct strength.
Apply the patch to a clean, dry, cool, flat area of skin on your upper body or arm. For children, always place it on the upper back so they cannot reach it. Change the patch every three days (72 hours).
The patch gives you medicine continuously for 72 hours (3 days), so there isn't a typical 'maximum daily dose'. Always follow your doctor's instructions for the patch strength.
