Common neuropathic pain syndromes are central neuropathic pain, painful diabetic peripheral neuropathy, postherpetic neuralgia, trigeminal neuralgia, postsurgical neuropathic pain, HIV-related neuropathy, lumbosacral radiculopathy and complex regional pain syndrome.

Capsaicin 8% patch shows potential as a long-term treatment option for non-diabetic patients with peripheral neuropathic pain, with a new study reporting that repeat treatment over 52 weeks is well tolerated, producing sustained reductions in average pain intensity with variable sensory function alteration and minimal chance of complete sensory loss.
