Final answer:
Patients must receive a patient product insert (PPI) when they are prescribed estrogens due to significant side effects and risks associated with their use.
Step-by-step explanation:
The medication that requires a patient product insert (PPI) to be provided to patients when they receive a prescription is estrogens (option b). Patient product inserts are mandatory for certain medications to ensure that patients are fully informed about the benefits and risks of their medication. Estrogens, used for hormone replacement therapy and various other conditions, are among the medications that the FDA requires to be dispensed with a PPI. This is because estrogens can have significant side effects and risks, including an increased risk of blood clots, stroke, and certain types of cancers. It is crucial for patients to have access to this information to make an informed decision about their treatment and to be aware of any potential side effects they need to monitor.
