Final answer:
The inability to fill a prescription for hydrocodone can be caused by factors such as missing DEA number, prescriber license number, and handwritten patient information.
Step-by-step explanation:
Several factors could contribute to a patient being unable to fill a prescription for hydrocodone, including:
- DEA number missing from prescription: The Drug Enforcement Administration (DEA) number is required on controlled substance prescriptions like hydrocodone. If this number is missing, the prescription cannot be filled.
- Prescriber license number not included: The prescriber's license number is another important requirement for filling a prescription. If it is missing, the pharmacy may not be able to fill the prescription.
- Patient name and date of birth were handwritten: Handwritten information on a prescription can sometimes be difficult to read, leading to errors or confusion. If the patient's name and date of birth were handwritten and not clear, the pharmacy may be unable to fill the prescription.
