A licensed pharmacist may lawfully provide prescription or medical information to a licensed health care provider or his agent who is legally qualified to administer medications and treatments and who is involved in the treatment of the patient. The information may be derived by direct contact with the prescriber or through a written protocol approved by the prescriber. Such information shall authorize the provider to administer appropriate medications and treatments.

4. Nothing in this section shall be construed to limit the authority of other licensed health care providers to prescribe, administer, or dispense medications and treatments within the scope of their professional practice.

5. It shall be an unauthorized practice of pharmacy and hence unlawful for any person other than the patient or the patient's authorized representative to accept a prescription presented to be dispensed unless that person is located on a premises licensed by the board as a pharmacy.
