Ed,
My own impression was that revlimid could stay in your system for up to 4 weeks after discontinuing use. This was never expressed to me by a doctor, however. It was from reading the literature concerning revlimid on Celgene’s website. There are several references related to “4 weeks” after discontinuing use of revlimid; for example, do not donate blood until 4 weeks after stopping use of revlimid, etc. I assumed the medicine could stay in your system that long after stopping its use. Hope that information helps.
Also, I’m very sorry to hear that both your wife and Carl had problems taking revlimid. I hope you are able to find success with other treatments and wish you all the best.
