Hi. I've recently been diagnosed with Crohns and I've been told by my consultant that I need to start taking Azathioprine. He says to start at 100mg increasing to 150mg after 2 weeks. I have received the medication from the chemist today as 50mg tablets and I am wondering about lengthening the start-up period and taking 50mg for 1 week and then go up to 100mg a week later and then 150mg 2 weeks after that so that it is a more gradual start. My thinking is that it may reduce the start up effects of this drug, ie. the nausea and head aches that people describe as getting. So has anyone had any experience with starting Azathioprine in a similar way to this or any other advise about how to go about starting it? Or is it actually best to just get it over with quickly rather than drag it out over a longer period. Hope someone can help. Thanks, Ben
