I have been searching the web for side effects to this antibiotic & found this site. My 20 month old daughter has also experienced the big itchy bumps all over her body & brick red stools from this medication. I have been told this is an allergic reaction & to use benedryl until everything clears up. I have also been told the red stools can be GI bleeding & if it is it will be mucasy or have red blood streaks in it & that it is very serious if so. I got my info from nurses & doctors over the telephone. I had planned to take my baby to the ER just to relieve my own worries, but after reading all the other people that had the same reaction I will just watch her closely. I would like to hear from those of you that have dealt with this reaction in your babies & how long it lasts & the ending results from this medication. Thanks :)
