Final answer:
Faxed prescriptions for Schedule II controlled substances can only be used as the original in specific cases such as patients in long-term care facilities or hospice care, and when the medication requires compounding for direct patient administration.
Step-by-step explanation:
Faxed C-II prescriptions may serve as the original in certain situations outlined by the Drug Enforcement Administration (DEA) regulations. According to the DEA, faxed prescriptions for Schedule II controlled substances can be considered original if they are for patients in a long-term care facility, or for a patient who requires hospice care, provided that the hospice is certified and licensed.
Additionally, in instances where C-II medications are to be compounded for direct administration to a patient by injection, infusion, or other means, a fax can serve as the original prescription. It is important for pharmacists to verify the validity of the fax and to ensure regulations are strictly followed to prevent misuse or diversion of these substances.
