I'm also suffering endless bouts of oral thrush since last October but as I've got both lupus & Sjogren's I've tended to put it down to the latter. Intrigued to discover that lupus can also be a cause as my GP feels I'm most likely currently in a flare. I've had thedx for 15 years almost but have only had one obvious flare through it, & can't say that I truly feel I'm in one now, but am beset by heavy fatigue, rashes, & hair loss so quite possible.
On the thrush - I've been on multiple short courses of fluconazole until Feb this year when my GP put me on a lower dose more chronically. That worked ok until we were concerned that some of my symptoms might be down to it, so I stopped it for a week or more, but as ever the thrush returned & is now breaking past the fluconazole which I resumed 10 days ago.
Has anyone else chopped & changed their anti-fungals or do you tend to stick with one other any other?
