Suspected Altered Controlled Prescription Presented by a Third Party
A 34-year-old man presents at 8:45 p.m. to your community pharmacy with a paper prescription for oxycodone 20 mg tablets, quantity 120, one tablet every 4 hours as needed for pain, for his 78-year-old grandmother. The prescription is written on a prescriber's pad, but the signature differs from the one on file, the quantity appears to have been altered from 20 to 120, and the prescriber's office is closed. The grandson says the pharmacy must fill it tonight because the family is driving to the United States tomorrow. The patient's profile shows no prior oxycodone 20 mg and only occasional oxycodone 5 mg from a year ago. The provincial prescription monitoring program shows a recent oxycodone 10 mg prescription from a different prescriber. The grandson becomes increasingly impatient and says his grandmother is in severe pain.
1. Identify the red flags and the legal and professional obligations that apply before any dispensing decision.

Red flags include an apparent alteration from 20 to 120 tablets, a signature that does not match the file, a high quantity of a controlled opioid, no recent oxycodone 20 mg on the profile, a different prescriber on the prescription monitoring program, third-party presentation, after-hours urgency, and travel pressure. Under the Controlled Drugs and Substances Act and provincial pharmacy legislation, the pharmacist must be satisfied that the prescription is authentic before dispensing. A pharmacist cannot dispense a prescription they believe is forged. Verify directly with the prescriber using an independently obtained number, not a number supplied by the patient. Check the prescription monitoring program. Do not dispense until authenticity is confirmed.
2. How will you communicate your decision to the grandson and to the prescriber?
Read the worked answer
Speak to the grandson privately and respectfully: 'I understand your grandmother is in pain, and I want to help. This prescription has details I must verify with the prescriber before I can dispense it. I cannot fill it tonight without that confirmation.' Avoid accusing him. Do not disclose the grandmother's health information to him unless he is authorized. Offer to contact the prescriber's on-call service or a walk-in clinic, and discuss safe interim options only if clinically appropriate. Document the conversation. If the prescriber confirms the prescription, dispense according to the verified order; if not, explain that you cannot fill it and provide the prescriber's contact information.
3. What documentation, follow-up, and reporting steps are required?
Read the worked answer
Document the prescription exactly as received, the red flags, the verification attempts, the prescription monitoring program check, who was contacted, and the outcome. Keep a copy or photograph only if permitted by provincial policy. Notify the pharmacy manager. Report the suspected forgery to the prescriber and, per jurisdictional requirements and pharmacy policy, to police and the provincial regulatory body. Do not confront or detain the patient. If the grandmother is a patient, consider a separate welfare check through the prescriber. Review controlled-drug verification procedures and staff training.
