Generic Name: diclofenac transdermal (dye KLOE fen ak)
Brand Names: Flector Patch
What is Flector?
Flector Patches contain diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac works by reducing substances in the body that cause pain and inflammation.
Flector is used to treat pain caused by minor sprains, strains, or bruising.
Flector may also be used for other purposes not listed in this medication guide.
Diclofenac can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use Flector just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Get emergency medical help if you have chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance while using Flector Patches.
Before using Flector, tell your doctor if you are allergic to any drugs, or if you have heart disease, congestive heart failure, high blood pressure, a history of heart attack or stroke, a history of stomach ulcer or bleeding, liver or kidney disease, a blood clotting disorder, asthma or polyps in your nose, or if you smoke.
While the risk of absorbing diclofenac into your bloodstream is low, an NSAID may cause life-threatening heart or circulation problems such as heart attack or stroke, especially if you use it long term.
Flector may also cause serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and can occur without warning while you are using Flector, especially in older adults.
Call your doctor at once if you have symptoms of stomach bleeding such as black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.
Before taking this medicine
The diclofenac in Flector patches can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Even people without heart disease or risk factors could have a stroke or heart attack while using Flector patches.
Do not use Flector just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Diclofenac may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Flector, especially in older adults.
You should not use Flector if you are allergic to diclofenac (Voltaren, Cataflam, Cambia, and others), or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.
To make sure Flector is safe for you, tell your doctor if you have:
heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;
a history of heart attack, stroke, or blood clot;
a history of stomach ulcers or bleeding;
liver or kidney disease;
Using Flector during the last 3 months of pregnancy may harm the unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether diclofenac transdermal passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using Flector.
Flector is not approved for use by anyone younger than 18 years old.
How should I use Flector Patches?
Use Flector Patches exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger amounts or for longer than recommended. Using extra skin patches will not make the medicine more effective, and could cause dangerous side effects.
Apply the skin patch directly to the area of pain. The skin patch can be worn for up to 12 hours and then removed. Apply a new patch at that time if pain continues.
Do not apply Flector on an open skin wound, or on areas of eczema, infection, skin rash, or burn injury.
Wash your hands after applying or removing a Flector skin 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 skin 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 skin patches out of the reach of children or pets.
If you use Flector long-term, you may need frequent medical tests.
The Flector patch may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test.
Store Flector at room temperature away from moisture and heat. Reseal the storage envelope each time you remove a patch from it.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

What happens if I miss a dose?
Apply a skin patch as soon as you remember, and wear it for 12 hours before applying a new one. Do not use extra patches to make up the missed dose. Do not wear a Flector skin patch for longer than 12 hours.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using Flector?
Do not wear a Flector skin patch while taking a bath or shower or while swimming.
Avoid getting a skin patch near your eyes, nose, or mouth. If this does happen, rinse with water. Call your doctor if you have eye irritation that lasts longer than 1 hour.
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Avoid taking aspirin or other NSAIDs.
Ask a doctor or pharmacist before using any cold, allergy, or pain medication. Many medicines available over the counter contain aspirin or other medicines similar to diclofenac. Taking certain products together can cause you to get too much of this type of medication. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.
