I have taken trimethoprim for two doses and those havent been as close as they should have been over two days and not the full dose at that as I took 200mg last night and felt so horrible, with a very dry mouth, high high anxiety couldnt sleep and didnt feel well at all.. depite drinking lots and lots as advised when taking it ..I just was starting to feel better during today as if it was wearing out of my system and I still have the urinary infection so tonight I took half a dose (ie 100mg) and here I am sitting up into the night scouring the Internet for side effects or drug interactions that may not be on the leaflet with the meds, but maybe what I am having, as I feel exactly the same as last night, high high anxiety, cant sleep and dry mouth (very). I dont think I want to continue this medication and will call my Dr tomorrow for another antibiotic to clear the UTI. Was quite releived when I came across this site with people mentioning high anxiety and very dry mouth and feeling plain awful!
