I have been on Cyclo for about 9 months now. I am sure your derm explained why you need weekly blood tests, blood pressure tests etc.
As far as side effects I've experienced go... I had bad stomach cramps and really hot finger tips (to the point where I had to put ice on them). They went away after about 2 weeks though. Long term, I've grown my self a wee lip brow (Not a problem for the gentlemen on cyclo).
Where my P is concerned though it's worked brilliantly! My derm put me on MTX first which worked well but my blood test results were never good. I took a break for a couple of months, in which time my P returned badly. After 2 or 3 weeks on Cyclo I had noticed a huge difference in my P, I almost clear, just a patch on my arm. 4 or 5 months in it did flare up again, my derm upped my dose a little and I am almost clear again.
