Hello,
Unfortunately,
NEUROBION is not a medication that has been evaluated by the FDA. Therefore, the claims made by the manufacturer are likely not supported by robust scientific evidence that could pass Phase 3 trial parameters.
The ingredients of this medication are 6 B complex vitamins. Bell's
Palsy has never been known to resolve or improve on the basis of such formulations.
Chewing or talking that causes the eyelid to close is referred to as
synkinesis for which no definitive treatment exists.
However, there are a number of approaches that can make things better for certain people.
I believe if you've not tried them then you should speak with your doctor about them such as Facial Muscle retraining, BIOFEEDBACK THERAPY, Mime therapy,
BOTOX, Transcutaneous Electrical
Nerve Stimulation, and even surgery.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
