I'm on Azathioprine. It takes about 6 weeks to kick in when you first start taking it. To figure out how long a drug stays in the body, you need to know its "half life", which means the amount of time that it takes for the medication to be eliminated by the body. I've included a link as to how to figure it out. It requires simple math. When you find out the half life of a med, divide that number by 4 and you'll get the number of days that the med is active in your body. For Azathioprine, the half life is 5 hours (approximately). So when you divide 5 by 4, you get about 1.25 days. So you can't miss a dose! It stays in your system for about 1 day. I hope this is helpful!

Cellcept's half life is 18 hours. So 18 divided by 4 is 4.5 days. It's longer lasting in the body. I know Lynnwood will have some great information for you. She's our Cellcept expert . I'm not sure how long it takes for Cellcept to "kick in".
I've had tremendous success with Azathioprine (Imuran). You'll need to get monthly blood work done to watch your lymphocytes, and kidney function.
Good luck with tapering off your pred! That will be a day to celebrate!!
