Aspercreme Lidocaine Patch is an over-the-counter topical analgesic delivered via an adhesive patch that adheres to the skin over sore muscles or joints. The patch releases lidocaine to numb the targeted area and help relieve minor aches, strains, and pains. Typical use involves cleaning and drying the skin, applying the patch to the affected area, and wearing for the recommended duration per package instructions. Individually packaged patches offer portability and hygienic storage.
