Prescription and Pharmaceutical Practice, Including Controlled Substances
Therapeutic pharmaceutical practice is where scope, prescribing law, and controlled-substance regulation intersect.
Authority and registration
Oklahoma licenses optometrists with therapeutic privileges to administer and prescribe topical and oral agents for ocular disease. Before writing for a controlled dangerous substance, the licensee needs more than a license: an Oklahoma State Bureau of Narcotics and Dangerous Drugs Control (OBNDD) registration and a DEA registration, and the prescription must fall within the schedules the Act and Board rules authorize optometrists to prescribe.
Prescription requirements
A valid prescription identifies the patient, drug, strength, dosage form, quantity, directions, date, and prescriber, with the prescriber's DEA and OBNDD numbers on controlled substances. Federal rules bar refills on Schedule II drugs and limit refills on Schedule III–V. Prescriptions must issue for a legitimate therapeutic purpose after an examination establishing the diagnosis.
Monitoring and limits
Oklahoma maintains a prescription monitoring program; prescribers must query it and document the review when prescribing controlled substances, and state law limits initial opioid prescriptions for acute pain to a short supply with defined exceptions. Electronic prescribing of controlled substances requires a DEA-compliant system.
Worked example
A patient with adenoviral conjunctivitis demands "codeine drops." The correct analysis: the diagnosis is viral and does not support an opioid, and prescribing without a legitimate medical purpose violates Board rules and federal law regardless of patient request. Document the refusal and the supportive plan.
Traps
- Assuming a DEA number alone satisfies Oklahoma registration.
- Prescribing controlled substances for self, family, or staff without a documented patient relationship.
- Refilling a Schedule II prescription.
- Omitting the diagnosis that justified the drug from the record.
