Over the past few days I've felt off and had discomfort in my bladder and lower down and was diagnosed with a UTI just yesterday.
I began taking trimethoprim last night, taking two tablets immediately like that prescription said and then taking one per night after.
However over night after taking two tablets at about 2.30 pm (it is now 8am the next day), my symptoms have worsened and have turned painful with a very high bladder pressure.
My experience with Keflex - Keflex usually kicks in by now but I can't take it because I've already had it three times this year.
I was wondering if this means trimethoprim is not working or if it just needs more time to kick in? Keep in mind its only been 17.5 hours since I took the initial double dose.
