urinary tract infection
"I suffer from an eye inflamation disorder, and am on doxy for life, so when i had a UTI recently I just upped the dosage - Thought I would share a few of the more common side effects with you. 1st is Nausea - if you shock your system with it (Doxy is a VERY powerful broad spectrum antibiotic) by taking too much too quickly you are likely to get lightheaded and nauseous about an hour after taking it - symptoms persist for another hour or so, and then goes away - best bet is spread it out but with a lower dose - 50mg 4 x a day is just as effective as 100mg twice a day, but causes MUCH fewer symptoms. Secondly - this WILL destroy your natural gastrointestinal flaura and after 3 days or so you will get looser stools and your gas will be BAD"
