Is Botox Safe for Patient Who Had Guillain-Barré?

The simple answer is NO! Allergan clearly places on it's product labeling that BOTOX certain neuromuscular diseases. Gillian-Barré is one of the diseases on that list. Hope this helpful.

I would not treat a patient who has a diagnosis of Guillain Barre. There might be a neurologic disease that could safely have the treatment with Botox, such as some cases with multiple sclerosis if the treating neurologist approves the low dose skin use of the botulinum toxin. It must be a team approach of the injecting physician and neurologist discussing the patient care.

Guillain-barre is one of the specific neuromuscular conditions where Botox should not be done. However there is a big difference between Gillain-Barre that is active versus resolved. Your friend should discuss her current status with her neurologist regard her current status.

Botox is clearly contraindicated in individuals with a history of Guillan-Barre syndrome.  Your friend should avoid anyone who would be willing to inject a neurotoxin with his history of a neuromuscular disease.

As complicated as our immune system is, we still do not understand the exact pathophysiology of Guillain-Barré. No one knows what are the consequences of botulinum toxin injection into a Guillain-Barré patient, whose immune systems is very disturbed. Is it possible that Botulinum toxin injection may benefit such patients? It may but we do not know.
