Diclofenac Transdermal Patch Dosage
- Transdermal diclofenac comes as a patch to apply to the skin. Diclofenac patches are usually applied two times a day, once every 12 hours. Apply diclofenac patches at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Do not apply more or fewer patches or apply patches more often than prescribed by your doctor.
- Do not apply diclofenac patches to skin that is broken, damaged, cut, infected, or covered by a rash.
- Do not let the patches come in contact with your eyes, nose, or mouth. If the patch does touch your eye, wash the eye out immediately with water or saline. Call a doctor if there is eye irritation that lasts for more than one hour.
- Do not wear a patch while bathing or showering. Plan to bathe or shower after you remove a patch and before you apply the next patch.
- To apply diclofenac transdermal patches, follow these steps:
- Wash the skin area where you will apply the patch with soap and water. Do not use any moisturizing soaps, lotions, astringents, or other skincare products on the chosen skin area.
- Completely dry the skin area where you will be applying the patch.
- Cut open the envelope containing the patches, cutting on the dotted line and making sure not to cut the zipper seal just below it.
- Pull apart the zipper seal on the envelope and remove one patch. Reseal the envelope by squeezing the zipper seal together. Make sure the envelope is closed tightly to keep the patches inside from drying out.
- Fold over one corner of the patch and gently rub the folded corner between your finger and thumb to separate the patch from the clear liner that is attached to the sticky side. Peel off the entire liner.
- Firmly press the patch into place on the chosen skin area. Press down around all four edges to secure the patch.
- The patch may begin to peel off while you are wearing it. If this happens, tape down the edges of the patch with first aid tape.
- When you remove a diclofenac transdermal patch, fold it in half so that it sticks to itself and throw it away in a garbage can that is out of the reach of children and pets.
- Wash your hands when you are finished applying or handling the patch.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription of diclofenac transdermal.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
