Versatis is a medicated plaster that is primarily used for the topical treatment of neuropathic pain associated with previous herpes zoster infection, also known as post-herpetic neuralgia. Each plaster contains lidocaine, an active ingredient that works by providing local anesthetic effects. Lidocaine operates by blocking the pain signals at the skin level, offering relief from the discomfort associated with this condition. Versatis plasters are designed for direct application to the skin over the painful area, providing targeted and localized pain relief. The plasters are adhesive, ensuring they stay in place to deliver the medication over a sustained period, typically recommended for use for up to 12 hours within a 24-hour period. This medication is available by prescription and should be used under the guidance of a healthcare professional to ensure proper application and to minimize potential side effects.
