Hi, I have been on azathioprine since April 2016 so 3 months. Before starting meds I never got the flu/colds or if I did I'd be over them in a couple of days. However, I seem to be getting a mini flu/awful cold every few weeks. I've had a cough after one of these colds for three weeks now and it's not letting up. I now feel like I am coming down with yet another mini flu when I'm not really over the last one!. I was freezing at work today with 5 layers on while other people I noticed were in t-shirts. I am seeing my GI tomorrow and was hoping I could increase my dose to 75mg but worried this will make the colds worse. Any advice on this? When searching the forum it seems most people don't get colds any more usual so I don't know what is going on with me. I am only on a small dose - 50mg, I am about 5 foot 5 and weigh 50 kg. is it possible I'm not tolerating the drug or maybe just over exposing myself to sick people?! I have been having fortnightly blood tests but no clue what that have been showing. Maybe my GI will reveal tomorrow.
