Our pharmacist-built guide to Lidocaine Transdermal Patch: what it is, how it’s used, side effects, and interactions.

📗 Our plain-language guide HelloPharmacist
  • It relieves nerve pain from post-herpetic neuralgia, the lingering pain that can follow shingles. It is used in adults. It numbs the pain signals in the skin under the patch.
  • Usually up to 12 hours in a 24-hour period, then 12 hours off. Put it on intact skin over the most painful spot. Do not use more patches than prescribed.
  • No. Heat can increase how much lidocaine gets absorbed. With Ztlido, you can apply a patch after brief heat, but never put a heating pad or electric blanket directly on it.
  • For Ztlido, light exercise and short water exposure, like a 10-minute shower, are okay. Gently pat it dry rather than rubbing. If the edges lift, press them down.

These are official RxNorm vocabulary relationships — how concepts name and organize the same medicine. They do not establish therapeutic equivalence or substitutability: two concepts appearing in one web is never a statement that products can be swapped.

🔀 Generic ⇄ Brand Crosswalk

The same medicine has an unbranded (generic) identity and one or more brand-name identities — each with its own RxCUI. This is a naming relationship in RxNorm, not a statement that any two products are substitutable.

  • A shared RxCUI does not prove interchangeability. Products mapped to the same concept are not thereby equivalent or substitutable — equivalence is a separate, product-level determination.
  • Listing here does not establish approval or coverage. Appearing in this snapshot is a data observation, not an FDA approval status or a payer coverage decision.
  • Missing data never means zero. A silent dataset (no price, no billing code, no utilization) means no observation — not that the real-world value is zero.
  • Counts describe the mapping footprint. Product, package, and labeler counts are the FDA-listed mapping footprint in this snapshot — not sales, inventory, availability, or market share.
