PREGNANCY AND BREASTFEEDING SAFETY: There are no adequate studies done on lidocaine patches to determine safe and effective use in pregnant women.
Lidocaine may enter breast milk in trace amounts; therefore, it is best to be cautious before using it in nursing mothers.
STORAGE: Store lidocaine patches between temperatures of 15 C to 30 C (59 F to 86 F).
DOSING: The recommended dose for lidocaine patches is to apply up to three patches, for up to 12 hours within a 24-hour period. Apply patches to intact skin to cover the most painful area; apply to intact skin, not over blisters or other skin that is not intact.
DRUG CLASS AND MECHANISM: Lidocaine is an amide-type, local anesthetic medication available in a patch form. Lidocaine, like other local anesthetics causes a loss of sensation by reducing the flow of sodium in and out nerves to decrease the initiation and transfer of nerve signals. The FDA approved lidocaine patch in March 1999.
