NO (unless...): B12 and B complex are often combined together and are extremely safe. I've given this combo to many people and the only side effect I've seen is temporary pain at the injection site.Of course I always give in in the hip region or arm. The only way I could see this happening is if it was actually injected into the person's face and damaged a nerve, but it should always be given in a large muscle.
