GB syndrome can occurr is association with various conditions, as a paraneopastic syndrome or secondary to a viral infection. Rituximab has also been reported to be associated with causing GB, probably through its anti-immune effect. There are also reports of rituximab association with improvement in GB. Review of the literature finds only case report level evidence to support rituximab for GB. The plan states: “Experimental means any treatment where the stated proposed treatment has no supporting literature for safety or efficacy in human trials”. Since this is the case for rituximab for GB, it should be considered investigational.
