Post-Extraction Opioid, PDMP, and a Refill Request
A Mississippi general dentist removes a mandibular third molar on Friday afternoon and prescribes hydrocodone 5/325 mg, 20 tablets, with no refills. The patient reports taking alprazolam 0.5 mg daily and gabapentin 300 mg three times daily. The dentist checked the Mississippi Prescription Monitoring Program before prescribing and saw a recent hydrocodone prescription from an urgent care clinic and a benzodiazepine from a psychiatrist. The patient calls Saturday evening saying the pain is 10 out of 10 and requests a refill; the dentist is out of town and asks the hygienist to call the pharmacy and authorize six more tablets. The hygienist has no prescribing authority. The practice also holds a moderate sedation permit, but the dentist did not use sedation for this case.
1. May the hygienist call the pharmacy and authorize the refill? Explain the delegation and prescribing issues.

No. A hygienist cannot prescribe, call in, or authorize a refill. Mississippi's prescribing authority rests with the dentist, and the dentist must make the clinical decision after an appropriate evaluation. The dentist is out of town, but that does not let the hygienist act as a prescriber or proxy. The dentist could personally call the pharmacy only after assessing the patient - ideally in person or via an allowed telehealth modality - and reviewing the PDMP again. If the dentist cannot assess, the patient should be directed to urgent care or emergency care, not given a phone refill by the hygienist. The hygienist can help by documenting the call, checking the chart, and relaying information, but must not state 'the dentist approved' unless the dentist actually did. A refill of a Schedule II opioid also cannot be authorized on an existing prescription with no refills; a new prescription would be required.
2. What should the dentist do about the PDMP findings and the patient's pain report?
Read the worked answer
The combination of an opioid, a benzodiazepine, and gabapentin raises serious respiratory-depression risk, especially with a 10 out of 10 pain report. The PDMP shows another hydrocodone prescriber and a psychiatrist's benzodiazepine, so the dentist should not simply add more opioid. Recheck the PDMP before any new prescription, document the rationale, consider NSAIDs and acetaminophen, discuss risks, and use the lowest effective quantity. Mississippi law requires PDMP use in specified circumstances; the dentist should follow the current rule and document that the query was made. A 10 out of 10 pain score is not by itself a reason for a refill; look for infection, dry socket, fracture, or another cause. If the dentist is unavailable, arrange coverage rather than letting the hygienist improvise.
3. Does the moderate sedation permit change the analysis or authorize anyone else to prescribe?
Read the worked answer
The moderate sedation permit is irrelevant to the refill request. It authorizes the dentist to provide moderate sedation only under the permit's requirements - training, equipment, monitoring, emergency drugs, and possibly a second qualified person. It does not give the hygienist prescribing authority and does not convert an opioid refill into a delegated task. If sedation had been used, the permit and monitoring rules would apply to that sedation, not to after-hours prescribing. The practice should keep the permit current and ensure staff know which procedures are covered. For this patient, the dentist should document that no sedation was used, assess the pain, and follow prescribing and PDMP rules. The hygienist's role is limited to patient education and documentation within scope.
