Having been diagnosed with WG in sept 2011, I have now finished chemo 3 mnth ago and currently on Azathiaprine 200mg daily. I am also on Furosemide 40mg and Candesartan 8mg as b/p was slightly high and because I have kidney damage my consultant wanted b/p 130/75. This has been fine up to now but this last week my b/p has started to drop below this and after speaking to my vasculitis nurse on fri morn she sugg only taking half the dose of Furosemide and monitor my b/p daily. I have done this and I know it is only one day on but today I had a reading of 93/59. I am getting light headed and fuzzy feeling. Does anybody know how low I should let this go before I seek medical help. I will be ringing my consultant first thing monday morn but just a bit worried.
