This product is used to help reduce itching and pain from certain skin conditions (such as scrapes, minor skin irritations, insect bites). It may also be used to help relieve nerve pain after shingles (infection with herpes zoster virus). Lidocaine belongs to a class of drugs known as local anesthetics. It works by causing a temporary loss of feeling in the area where you apply the patch.
How to use Lidocaine Hcl 4 % Topical Patch
If you are using the over-the-counter product to self-treat, read and follow all directions on the product package before using this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, use it as directed.
Remove the protective liner and apply the patch to the skin area that is most painful. Apply the prescribed number of patches as directed by your doctor, usually once a day. Depending on your product, the patch may be left on the skin for up to 8 or 12 hours. Follow the instructions carefully. Do not apply more than 3 patches once a day or leave any patch on for longer than the stated time period. If a smaller patch is needed, it may be cut with scissors before the liner is removed. It is best to avoid getting the patch wet since it may not stick to the skin. Some brands may be wet in water for a short time (such as showering for10 minutes). Pat dry gently if you get the patch wet.
Wash your hands well after each application. Avoid getting this medication in your eyes or mucous membranes (e.g., nose, mouth). If contact with the eyes accidentally occurs, wash your eyes right away with water and protect them until normal feeling returns.
If your condition does not get better, or if it gets worse, or if you think you may have a serious medical problem, get medical help right away.
Used patches still contain some medication. However, do not reuse them. Fold the used patch with the sticky sides together and discard it out of the reach of children and pets to prevent accidental swallowing or application.
