How should I use diclofenac topical system?
Follow all directions on your prescription label and read all medication guides. Use the lowest dose that is effective in treating your condition.

Apply the topical system directly to the area of pain. The patch can be worn for up to 12 hours and then removed. Apply a new patch at that time if pain continues.

Wash your hands after applying or removing a patch.
If the patch does not stick well, you may place medical tape around the edges. You may also use a mesh netting sleeve to hold a patch in place on your skin. Do not cover the patch with a bandage or other covering that does not allow air to pass through.
After removing a patch, fold it in half, sticky side in, and throw it away in a place where children or pets cannot get to it. Keep both used and unused patches out of the reach of children or pets.
If you use this medicine long-term, you may need frequent medical tests.
Store at room temperature away from moisture and heat. Reseal the storage envelope each time you remove a patch from it.
