Does topical lidocaine have any side effects?

Donna Hill Howes, RN
Family Practitioner

Side effects may include redness, swelling, itching, or red or purple spots where the patch is applied. These may be worse if it is applied to broken or irritated skin. Children and the elderly may be more sensitive to lidocaine's systemic effects. Lidocaine should not be used where it could get into the ear.
