Do not use this medicine on open wounds or on sunburned, windburned, dry, chapped, or irritated skin. If this medicine gets in your eyes, nose, mouth, rectum, or vagina, rinse with water.

To apply a capsaicin topical skin patch, remove the liner and apply the patch to your skin over the area of pain. Press the edges firmly into place. Remove the patch and apply a new patch 1 or 2 times daily if needed.
Wash your hands with soap and water immediately after applying capsaicin topical or handling the skin patch. If you have applied the medicine to your hands or fingers to treat pain in those areas, wait at least 30 minutes before washing your hands.
To keep the medication from getting on your fingers when you apply it, you may use a rubber glove, finger cot, cotton ball, or clean tissue to apply the medicine.
Capsaicin can cause a burning sensation wherever it is applied. This sensation is usually mild and should gradually lessen over time with continued regular use of the medicine.
If the burning sensation is painful or causes significant discomfort, wash the treated skin area with soap and cool water. Get medical attention right away if you have severe burning, pain, swelling, or blistering.
Do not cover treated skin with a bandage or heating pad, which can increase the burning sensation. You may cover the skin with clothing.
Avoid taking a bath or shower within 1 hour before or after you apply capsaicin to your skin. Also avoid swimming or vigorous exercise. Warm water or perspiration can increase the burning sensation caused by capsaicin.
Avoid getting capsaicin topical in your eyes or near your nose where you might inhale it. If it does get into any of these areas, rinse thoroughly with water.
Also avoid getting this medication on contact lenses, dentures, and other items that come into contact with sensitive areas of your body.
It may take up to 2 weeks of using this medicine regularly before your symptoms improve. For best results, keep using the medication as directed. Pain relief should occur gradually as the substance P in your body is decreased in the nerve cells.
