Uses
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 topical
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.
This product should only be applied to normal intact skin. Do not apply to skin that is broken or irritated. The dosage is based on your medical condition and response to treatment.
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 (such as 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.
Side Effects
Redness, swelling, blisters, or changes in skin color at the site of application may occur. These effects usually disappear within a few minutes or hours. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
If irritation or a burning feeling occurs, remove the patch(es) and do not reapply until the irritation is gone.
If your doctor has directed you to use this medication, remember that your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: blurred vision, mental/mood changes (such as nervousness, confusion), drowsiness, dizziness, unusually slow heartbeat.
Get medical help right away if you have any very serious side effects, including: pale/bluish/gray skin, unusual tiredness, shortness of breath, fast heartbeat.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
