Hi I have SLE, DLE and Fibromyalgia. I have a suspected kidney infection and yesterday I was prescribed Trimethorpin but after checking if it was safe to take with SLE I found out it was a sulphar based antibiotic and therefore I shouldn't take it with SLE. I was then prescribed Nitrofurantoin, however when I checked the patient information leaflet alarm bells rang as I appear to have some of the issues this antibiotic can cause. So I haven't started to take it yet and just wondered if anyone had any advice as to whether or not they know if it is safe to take with SLE. I would like to add that all this was done without a gp actually seeing me in person.
