Mary begins her day at the compounding pharmacy; she is happy to be putting her education into practice. One of the prescriptions she must fill is amoxicillin for a baby with otitis media. She knows the drug needs to be reconstituted before it is dispensed. This was a call-in prescription, and the baby’s parent will be in around noon to pick it up. What is the proper procedure Mary should follow in this situation? What would happen if Mary prepared the amoxicillin before the parent arrives?
