Hi, everyone I haven't posted in a while. Just wanted some advice my azathioprine 50mg has been increased to 75mg this also I was taking the generic but decided to go for the brand. .( imuran). Well I have had the worst week I've had loss appetite, nausea, and muscle pain and also fatigue. I rang my gp yesterday who adv nothing to do with brand, but my bodey is not tolerating the increase. She told me to go back on 50mg and ring my rhumy..😔 any one else experienced this.. Thanks in advance.
