OBJECTIVE: Postherpetic neuralgia (PHN) is a neuropathic pain syndrome following herpes zoster (HZ) infection, characterized by pain that persists for months to years after the resolution of the HZ rash. Therapeutic management remains challenging for every clinician.

We report the follow-up of patients diagnosed with PHN and treated with lidocaine 700 mg medicated plaster (LMP), focusing on effectiveness, safety, and Quality of Life (QoL).

MATERIALS AND METHODS: This study is a retrospective observational investigation of patients with PHN treated with LMP. Patients were regularly followed for pain intensity, co-analgesic consumption, adverse effects, QoL using the EQ-5D, and patient satisfaction for 8 weeks.

RESULTS: A total of 31 patients were evaluated. At enrollment, 18 patients (58.1%) were treated with at least one PHN concomitant medication, for which the number and dosing remained constant during the study. Patients had a mean average pain intensity of 6.5±1.0 at baseline, which decreased to 3.6±1.1 at week 4 and 2.8±0.9 at week 8. Four patients reported erythema, and one complained of vesicles eruption associated with pruritus. EQ-5D at weeks 4 and 8 of treatment showed persisting improvements in all domains except for the “anxiety/depression” domain. At week 8, <80% of patients reported to be satisfied or very satisfied.

CONCLUSIONS: This study adds further weight to the growing body of clinical and research evidence that LMP treatment is effective and well-tolerated in patients with PHN.
