i have a throat and chest infection and I was put on antibiotics (amoxyllin), I took one last night and another this morning.... my baby, who has a tendency to allergy, has had a sudden flare up in eczema and ichiness, plus is very irritable. Could she be allergic to the antibiotics? my husband's going to take us both back to the doctor later today (they're not open now), but how can I tell if it was caused by the antibiotics or not? I haven't eaten any new foods today, and neither has she. So i don't know what else could have caused it??
