What are the side effects of transdermal lidocaine patches?

Explanation:
The main idea is that transdermal lidocaine patches most commonly cause local skin reactions because the drug is applied directly to the skin. The patch delivers lidocaine to the nerves near the surface, so the most frequent adverse effect is mild skin irritation or inflammation at the application site—redness, itching, or a light dermatitis from the adhesive and the medication itself. Systemic symptoms like nausea, headache, or dizziness can occur if more lidocaine is absorbed into the bloodstream, but these are less common when the patch is used as directed. Therefore, mild skin irritation or inflammation is the best-supported side effect.
