Background: Diabetic peripheral neuropathic pain (DPNP) is a debilitating and distressing complication that occurs in patients with diabetes mellitus. This article provides an overview of diabetic peripheral neuropathy focusing on DPNP.

Methods: This article reviews the diagnosis, pathogenesis, prevention and treatment of diabetic neuropathy and neuropathic pain. A comprehensive and systematic Medline search of the published literature for treatment of diabetic peripheral neuropathy was done from 1965 to December 2012. Studies not in English language were excluded.

Conclusions: Neuropathic pain is difficult to treat, and patients rarely experience complete pain relief. Despite several pharmacological agents being used in the treatment of DPNP, only duloxetine and pregabalin have evidence-based support for controlling DPNP.
