Diabetic neuropathy is a risk factor for developing complications such as autonomic cardiovascular disease, osteoarthropathy, foot ulcers, and infections, which may be the direct cause of death. Even worse, patients plagued by this condition display painful neuropathic symptoms that are usually severe and frequently lead to depression, anxiety, and sleep disarrays, eventually leading to a poor quality of life. There is a general interest in evaluating the therapeutic properties of topical capsaicin cream as an effective agent for pain relief in these patients. As such, the current review makes use of major search engines like PubMed and Google Scholar, to bring an updated analysis of clinical studies reporting on the therapeutic effects of capsaicin in patients with painful diabetic neuropathy. In fact, most of the summarized literature indicates that topical capsaicin (0.075 %) cream, when applied to the painful areas for approximately 8 weeks, can reduce pain, which may lead to clinical improvements in walking, working, and sleeping in patients with painful diabetic neuropathy. The current review also discusses essential information on capsaicin, including its source, bioavailability profile, as well as treatment doses and duration, to highlight its therapeutic potential.
