Why is this medication prescribed?

Capsaicin transdermal patch is prescribed primarily for the treatment of neuropathic pain associated with postherpetic neuralgia (PHN), which is pain that persists after an episode of shingles (herpes zoster). Capsaicin, derived from chili peppers, works by depleting substance P, a neurotransmitter involved in transmitting pain signals to the brain.

How should this medicine be used?

Here’s how Capsaicin Transdermal Patch should typically be used:

• Application: Apply the patch to the most painful area once daily for up to 12 hours. The affected area should be clean and dry before application.
• Preparation: Wash hands thoroughly after handling the patch to avoid inadvertently transferring capsaicin to sensitive areas (such as the eyes or mucous membranes).
• Duration: Treatment with capsaicin patches may require several weeks to achieve maximum effectiveness. It is important to use it regularly and as prescribed by your healthcare provider.
• Handling after use: After use, carefully remove the patch and dispose of it. Wash the treated area with soap and water to remove any residual capsaicin.
• Avoidance of contact: Avoid touching the patch once it is applied, especially touching the eyes or other sensitive areas, as capsaicin can cause irritation.
• Consultation: Always follow the specific instructions provided by your healthcare provider regarding the use of capsaicin patches. They can provide personalized guidance based on your condition and response to treatment.

It’s important to note that capsaicin patches are not suitable for everyone, and there may be specific precautions or contraindications depending on individual health conditions. Always consult your healthcare provider for guidance tailored to your situation.

What special precautions should I follow?
