I would call her pediatrician and ask for advice on what to do. She may need more IV fluids and viral testing. She may have a virus. They may want to do an abdominal ultrasound.

Was your daughter sick before the vomiting started? Antibiotics can cause side effects and may have caused the vomiting. She could also have an allergic reaction to the antibiotics causing her vomiting. What antibiotic was used for treatment? Did they give it for a known bacterial infection? Did she have food poisoning?
