  • Mine got a rash from Augmentin, and it was clear within 24 hours of stopping the med. I did not give Benadryl, as he was too young for it.

  • My son is allerigc to all cillin but so i am. It will take a couple of days before the rash goes away because the meds have to run it's course.

  • I had an allergic reaction to meds once and the doctors kept saying benadryl, finally they gave me steroids and then not enough and 3 weeks later they finally fixed it. If it is getting worse and not better I would probably call your ped again and tell them its not better.

  • your welcome. i knew my son would be allerigc to all cillin because i'm allerigc to all cillin and i asked my dr he said yep your and any future kids will. usaully if there is a family history of cillin allerigc in the family you kids get it from that but me i was the first one and only one in my family allerigc to it. me and my son both wear medical bracelet so they know not to give us penicili or any thign with cillin on the end.

  • My daughter had a bad reaction to penicillin too. I have 2 kids that can take it with no problem, and one that is allergic. Funny how each child you have can be so much alike and different at the same time!
