Finally after 16 months of 1st 10 months of Rituxan then 6 months of Cytoxan I will be transition to a matinance med. in June. Doc is leaning towards the Azathioprine. Other option being Methotrexate. Any opinions. Azathioprine looks better on paper but would like to hear from someone who is either on it now or has been in the past. Thanks!
