Is there gluten in RAN-Cefprozil, or is this vomiting a side effect? My daughter took it tonight and has been vomiting for 45 minutes.

It is possible that the vomiting your daughter is experiencing is a common side effect of taking Cefprozil. It is important to monitor her symptoms closely to ensure they do not worsen or indicate an allergic reaction. If she continues to vomit or experiences any skin rashes or difficulty breathing, it would be advisable to seek medical attention promptly. Remember to follow the dosage instructions provided and consult with a healthcare professional if you have any concerns about your daughter's reaction to the medication.
