Buprefarm patches are a strong medicine used to relieve moderate to severe long-lasting pain.
Your doctor will tell you which strength to use. Apply one patch to your skin and change it every seven days.
Apply the patch to a clean, dry, hairless area of skin on your upper arm, chest, or back. Press it firmly for 30 seconds to make sure it sticks well.
Do not use more than two patches at the same time, and the total dose should not be more than 40 micrograms per hour.
