(39yo female) I am on 20 mg per day after switching from Ritalin LA about a week ago. Low-grade fever recurs daily (about 3 days now), then disappears in evenings. Of course I could just be sick, but just wondering if it could be the meds? Weird thing is that yesterday I took RLA again because I forgot to take the FXR, but I had some Ritalin in my purse. I still got the fever, so not sure what's up?
