Hi, I'm new here. Diagnosed with generalized mg 7 years ago and neuro has tried everything. Currently he feels my only option left is cyclophosphamide and I have to give him a decision on whether to start it in 3 days time. Has anyone had any experience with this treatment in relation to myasthenia? Drug dosage? Duration of treatment? side effects esp. infertility? any info would be so helpful. Thankyou.
