Flector Patch

The Flector Patch is a medicated skin patch that is applied to the skin twice daily to relieve pain caused by bruises, sprains, and strains. It is available by prescription and only comes in one strength. The patch contains a nonsteroidal anti-inflammatory drug that works by blocking the production of various inflammatory substances in the body. Potential side effects of Flector include itching and nausea.

Who Makes the Flector Patch?

The Flector Patch is made by Teikoku Seiyaku Co., Ltd. and is distributed by Alpharma Pharmaceuticals LLC.
 

How Does the Flector Patch Work?

The Flector Patch contains diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Like other NSAIDs, it works by blocking a specific enzyme known as cyclooxygenase (COX), blocking the production of various inflammatory substances in the body. However, because it works mostly where it is applied (only a small fraction of the medication actually reaches the rest of the body), the Flector Patch helps to lower the exposure to the rest of the body (which may decrease the risk of dangerous side effects).
 

Clinical Effects of the Flector Patch

This medication has been thoroughly evaluated in clinical studies. These studies compared the Flector Patch to a placebo (a patch with no active ingredients). These studies showed that the Flector Patch was significantly better than the placebo for relieving short-term pain of sprains, strains, and bruises.
 

When and How to Use It

Some general considerations include the following:
 
  • The Flector Patch is usually applied to the skin twice a day.
     
  • Apply the patch to clean, dry, unbroken skin. Wash the skin with soap and water before application.
     
  • Do not swim or bathe while wearing the patch.
     
  • Do not use lotions, cosmetics, or any other products on the skin where you apply the patch. This may cause the patch to fall off or might interfere with the absorption of the medication.
     
  • Wash your hands after applying the patch.
     
  • If the Flector Patch appears to be coming loose, you may tape down the edges of the patch to the skin.
     
  • For the medication to work properly, it must be taken as prescribed.
