My 14 month old daughter gets blue lips (and some times hands) after she eats. This has been going on for 2 weeks. She has had chest x-ray, EKG, heart ultra sound, and a swallow test. All came back negative. She has been fighting an ear infection for 2 weeks. 6 days ago we started her on amoxicillin and she had an allergic reaction on Thursday (hives all over her body). We are on new meds for the ear infection. Could the blue lips/hands be explained by a food allergy? They seemed to be worse (more frequent and longer duration) when she was taking the amoxicillin.
Hi....by what you say, I feel that the blue lips are more likely to be due to Chat Doctor.  I suggest you stop the antibiotic immediately and approach your kids' pediatrician regarding this. Regards -
