This can be a real issue with some generic medications. You should be able to google the drug name and "consumer medicine information" to get a more complete list or you could go back to the pharmacist and get them to print out the full info from eMIMS.

Is it possible that the behavious is just a reaction to being unwell? It may be that if she's had the runs the ABs have not really being working so she may still be feeling unwell or in pain. I would take her back to the GP for a review, rule that out first.
