Final answer:
The pharmacy technician should alert the pharmacist when there is a Tamiflu shortage. The pharmacist can manage the inventory and suggest alternatives, and communicate with patients about the issue.
Step-by-step explanation:
When there is a shortage of Tamiflu in a pharmacy and patients are requesting prescriptions to be filled, the pharmacy technician should immediately alert the pharmacist on duty. The pharmacist has the responsibility to manage inventory and can provide alternatives to Tamiflu for treatment, such as suggesting generically equivalent drugs or therapeutical alternatives. It is also important to communicate effectively with patients, advising them about the shortage and providing information about potential wait times or directing them to another pharmacy if possible.
