Combination of local Botulinum toxin A injections and standard oral drug treatment allows improvement of long-term pain management in severe post-herpetic neuralgia: A case report

Systematic reviews showed that Botulinum toxin A (BoTN A) may be helpful in controlling neuropathic pain like in Post-herpetic Neuralgia (PHN). We introduce a case report on the effects of a long-term management with intracutaneous BoTN A injections combined with classic drug treatment in a patient with severe PHN. The combination of regular BoTN A therapy every three month and oral drug treatment allows to reduce pain rating with VAS by 50% and suggested that this combination may be helpful for long term management of severe PHN.
