I was on 300mg a day and then they upped me to 400mg a day after a flare up.
I stopped taking cyclo altogether for the first week in new year (I wasn't advised to, I was just having a strop with the stuff) and in that week the patches I had that weren't cleared up were bright red and very very itchy and I had some smaller patcher reoccurring.
I would prepare yourself to be told to stop taking Cyclo... perhaps there are other options out there for you. Cyclo is rarely a long-term thing and if it effecting your kidneys and BP, that's concerning.
Of course your derm will have the best solution - Best of luck on Monday xx
