Uti

Drink plain water hourly, at least a cupful. Also, try phasing in some natural cranberry juice (such as Knudsen's Just Cranberry), about a quarter cup 2X daily. Go low on sugary foods, drinks. Also better to avoid spicy foods, alcohol. Get plenty of rest & try to avoid stress. I know that UTI causes worry because ABX meds also wipe me out-- so I try hard to avoid them plus am highly allergic to some, besides. Good luck & take good care of yourself. / Old Hat (40 yrs with left-sided UC)

I tend to react poorly to antibiotics. I took macrobid and had no gi symptoms at all, just a bit of a headache. It was mild compared to others. I had very severe reactions to cipro and even flagyl (non GI though).

If you are seeing blood in your urine, then I wouldn't risk it especially if your immune system is suppressed. If you have to take it, increase probiotics.

I'm pretty limited on antibiotics, typically for UTI my dr gives me Bactrim, plus OTC Floraster. I try to catch them sooner rather than later, not much fun to end up in the hospital with one.
