I am currently being treated for h.pylori infection. I m taking Flagyl, Biaxin, and Prilosec. Two days ago I started having a strong bitter/metallic taste in my mouth along with a gritty sensation. I do have a white/yellow coating of the tongue. I battle with acid reflux and it has been worse since taking the antibiotics especially at night. I have no pain/discomfort. I brushed my tongue aggressively this morning so I do feel some soreness on my tongue right now. I have lupus and currently taking prednisone 5mg qd, plaquinil, Imuran 125 mg qd, Celebrex, and Coumadin. Its Thanksgiving can I wait until tomorrow to be seen? I don t have any yeast symptoms anywhere else right now. Thanks, Julie
