Neuropathic pain is a common condition and affecting 40 to 70% of the general population. Post-herpetic neuralgia is a condition almost complex and requires a multi modal treatment. Aim: This is a pilot proof-of-principle study designed to evaluate the use of low-dose methadone in post-herpetic neuralgia patients who remained refractory after first and second line treatment for post-herpetic neuralgia (PHN) and had indication for the association of an opioid agent to their current drug regimen.
