Important Dosage and Administration Instructions

‚ÄčBecause of the difference in bioavailability of ZTLIDO compared to Lidoderm (lidocaine patch 5%), a different dosage strength is required to be administered to the patient. One ZTLIDO (lidocaine topical system) 1.8% provides equivalent lidocaine exposure to one Lidoderm (lidocaine patch 5%) [see Clinical Pharmacology (12.3)].

When ZTLIDO is used concomitantly with other products containing local anesthetic agents, the total amount of drug absorbed from all formulations must be considered.

Clearly instruct and advise patients:

  • to wash hands immediately after handling ZTLIDO and to avoid contact with eyes [see Warnings and Precautions (5.6)].
  • to store ZTLIDO inside the sealed envelope out of the reach of children, pets, and others and to apply immediately after removal from the envelope.
  • to fold used ZTLIDO so that the adhesive side sticks to itself and to safely discard used ZTLIDO or pieces of cut ZTLIDO where children and pets cannot get to them [see Warnings and Precautions (5.1)].
  • to never apply external heat sources, such as heating pads or electric blankets, directly to ZTLIDO, because plasma lidocaine levels are increased. ZTLIDO can be applied, however, to the administration site after moderate heat exposure, such as 15 minutes of heating pad exposure on a medium setting [see Warnings and Precautions (5.2), Clinical Pharmacology (12.3)].
  • that clothing may be worn over the area of application.
  • that ZTLIDO may be used during moderate exercise, such as biking for 30 minutes.
  • that ZTLIDO may be exposed to water, such as showering for 10 minutes or immersion for 15 minutes.
  • to dry the topical system, after water exposure, by gently patting the skin, not by rubbing the skin or topical system.
  • that ZTLIDO topical systems that have lifted at the edges may be reattached by pressing firmly on the edges and that fully detached topical systems may be reapplied as originally directed.
  • that if a ZTLIDO topical system comes off completely and will not stick to patient's skin, to remove and properly dispose of the used ZTLIDO and to apply a new ZTLIDO topical system for a total duration of 12 hours of used and new topical system together.
  • that if irritation or a burning sensation occurs during application, to remove ZTLIDO and to not reapply until the irritation subsides [see Warnings and Precautions (5.4)].

Treatment of Post-Herpetic Neuralgia

Advise patients to apply ZTLIDO to intact skin to cover the most painful area and to apply the prescribed number of topical systems (maximum of 3), only once for up to 12 hours within a 24-hour period (12 hours on and 12 hours off) [see Warnings and Precautions (5.2)].

In patients who are debilitated or have impaired elimination, smaller areas of treatment are recommended. Achieve this by cutting ZTLIDO with scissors into a smaller size prior to removing the release liner.
