sinusitis
"I was prescribed amox-clav 875mg 2x a day for two weeks for infected adenoids in my sinuses.  I had not been taking it with a full glass of water but had been taking it with an early afternoon and late evening meal.  Doctor also prescribed Prilosec to be taking with it once a day.  From start I noticed a little bit of nausea with extreme fatigue on days 2 & 3.  On day four I woke up feel great assuming I slept better because the medicine must have been working.  However two hours after lunch I had severe nausea and stomach cramps and burning along with severe diarrhea.  Took 6 tums and the Prilosec earlier than normal and ate a lot plain crackers.  Burning lessened just a bit.  This medicine has awful side effects.  Need to call doctor."
