Lidocaine patches are topical medications that deliver a local anesthetic directly through the skin. They work by stopping nerves from sending pain signals, providing targeted relief for discomfort in a specific area of the body. These patches are used to reduce various types of pain, including muscle pain, nerve pain, and discomfort associated with conditions like shingles.
Before You Apply
Before applying a lidocaine patch, inspect the application site. The skin should be clean, dry, and free from irritation, rashes, open wounds, or cuts. Applying the patch to damaged skin can increase lidocaine absorption into the bloodstream, potentially leading to more side effects. Also, consider if the area will be rubbed by tight clothing, as this can affect patch adherence and absorption. Always consult the specific instructions provided with your patch, and discuss any allergies or existing medical conditions with a healthcare professional before use.
Applying the Patch
Open the protective pouch, avoiding the adhesive side. Remove the protective liner, typically by grasping both ends and pulling. If cutting is needed for a specific area, do so with scissors before removing the liner. Place the patch firmly on clean, intact skin, ensuring it adheres well. Apply only the prescribed number of patches, usually no more than three at a time, for the recommended duration (often 8-12 hours within 24 hours).
Removing and Disposing of Patches
When wear time is complete, gently peel the patch off. Used patches still contain medication and must be disposed of carefully to prevent accidental exposure to children or pets. Fold the used patch so sticky sides adhere, enclosing medication. Place the folded patch into a sealed bag or sturdy container, preferably with a child-resistant cap, before discarding. After handling, wash hands thoroughly to remove any residual medication.
Essential Safety Guidance
Lidocaine patches can cause side effects. Common skin reactions at the application site include redness, itching, or a burning sensation. If severe or persistent, remove the patch and contact your doctor. More serious, though less common, side effects requiring immediate medical attention include hives, rash, difficulty breathing or swallowing, swelling of the face or throat, an unusually fast pulse, confusion, or seizures.
Avoid using heating pads, electric blankets, or other external heat sources over the patch, as this increases lidocaine absorption and the risk of adverse effects. Store unused patches safely away from children and pets, at room temperature and sealed in their original packaging. Adhering to prescribed dosage and application instructions minimizes risks.
