Note:

1. Riluzole - The National Institute for Clinical Excellence (NICE) has recommended riluzole to treat individuals with the amyotrophic lateral sclerosis (ALS) form of motor neurone disease (MND) - see NICE TA20. Treatment should be initiated by a specialist in MND but it should then be supervised under a shared-care arrangement involving the general practioner.

2. Botulinum A toxin - There are three botulinum A toxin products (Botox, Dysport and Xeomin). Doses for these products are not interchangeable, and licensed indications may vary from product to product.

3. Botulinum B toxin is approved for use in the Trust for the unlicensed indication of sialorrhoea. 

Guidelines for the administration of botulinum toxin for cervical dystonia, hemi-facial spasm, blepharospasm, and sialorrhoea are available.
