- An optometrist with therapeutic prescriptive authority writes a prescription for latanoprost ophthalmic solution for a patient with glaucoma. On the same prescription blank, they add a prescription for oral hydrocodone/acetaminophen 5/325 for severe eye pain.
Answer: The validity of the hydrocodone/acetaminophen prescription depends on state law defining the optometrist's authority to prescribe controlled substances.
The authority of optometrists to prescribe medications, especially controlled substances, is determined by state law, not federal law. While all states grant some level of therapeutic authority, the scope varies significantly. Some states allow optometrists to prescribe a limited formulary of oral medications, including certain controlled substances for pain, while others do not. Therefore, the validity of the hydrocodone prescription is entirely dependent on the specific state's laws and regulations.
- A pharmacy receives an electronically prescribed order for zolpidem (C-IV) for a new patient. The patient states they had a video consultation with a prescriber from a telehealth service. The prescriber is in another state and has never physically examined the patient.
Answer: The prescription is valid if the telehealth consultation was conducted using real-time, two-way audio-visual communication.
The Ryan Haight Act generally requires an in-person medical evaluation before prescribing controlled substances. However, a key exception exists for telemedicine practices where the consultation is conducted via a real-time, two-way, audio-visual communication system. This technology is considered a legitimate way to establish a prescriber-patient relationship for the purpose of prescribing.
- A patient who is a regular customer presents a new, validly written paper prescription for lisinopril. The pharmacist notices that the patient's address is not written on the prescription form.
Answer: The pharmacist can fill the prescription, as the patient's address can be readily obtained from pharmacy records and added.
Under federal law (21 CFR § 1306.05), the patient's full address is a required element on prescriptions for controlled substances. For non-controlled substances, state laws govern, and most states permit the pharmacist to add or confirm the address if it is missing, especially if the patient is established and the information is available in the pharmacy's records.
- A community pharmacy receives a faxed prescription for a fentanyl patch. The cover sheet indicates the patient is enrolled in a Medicare-certified hospice program and the prescription states it is for pain management.
Answer: The faxed prescription can serve as the original, legal prescription for this patient.
Federal law provides specific exceptions allowing a faxed prescription for a Schedule II substance to serve as the original prescription. One of these exceptions is for a patient enrolled in a hospice care program certified and/or paid for by Medicare. The prescriber or agent must note on the prescription that the patient is a hospice patient.
- A pharmacist at a community pharmacy receives a written prescription for oxycodone/acetaminophen from a medical resident for a patient being discharged from a hospital. The prescription contains the hospital's DEA number followed by the resident's unique suffix.
Answer: The prescription is valid, as residents are authorized to use their hospital's DEA registration with an assigned internal code.
Federal regulations (21 CFR § 1301.22(c)) allow institutional practitioners (like hospitals) to permit unlicensed interns, residents, or foreign-trained physicians to dispense and prescribe controlled substances under the hospital's DEA registration. The practitioner must be assigned a specific internal code as a suffix to the hospital's DEA number.
- A dentist writes a prescription for atorvastatin for a patient who mentions during a dental cleaning that they have high cholesterol and ran out of refills from their primary care physician. The prescription contains all required patient and prescriber information.
Answer: The prescription is invalid because treatment for hyperlipidemia is outside a dentist's scope of practice.
A prescription must be for a legitimate medical purpose within the prescriber's usual course of professional practice. A dentist's scope of practice is generally limited to the mouth, jaw, and associated structures. Prescribing for a systemic condition like high cholesterol is outside this scope, making the prescription invalid.
- A pharmacist receives an e-prescription for phentermine (C-IV) from an out-of-state 'weight-loss clinic.' Upon calling the patient for counseling, the patient confirms they only filled out an online health questionnaire and never had a real-time conversation with the prescriber.
Answer: The prescription is invalid as it was not issued for a legitimate medical purpose pursuant to a valid patient-prescriber relationship.
The Ryan Haight Act requires that the prescribing of a controlled substance be preceded by at least one in-person medical evaluation of the patient (with some exceptions, like specific telemedicine encounters). A prescription based solely on an online questionnaire does not establish a valid patient-prescriber relationship, rendering the prescription illegitimate and invalid. The pharmacist's corresponding responsibility requires them to refuse to fill it.
- A nurse from a physician's office calls in a new prescription for metformin for a patient. The nurse states the physician has authorized the prescription, but the physician is currently with another patient and cannot speak on the phone.
Answer: The prescription is valid, as a nurse or other office staff can act as the prescriber's designated agent to communicate an order.
Prescribers may authorize an agent (such as a nurse or medical assistant) to communicate a prescription to a pharmacy on their behalf. This is permissible for non-controlled substances. The agent is not prescribing, but rather transmitting the prescriber's order. For controlled substances, the rules are more restrictive.
- On June 1st, a patient requests a refill of their enalapril prescription. The pharmacist sees the prescription has 5 remaining refills. The pharmacist is aware that the prescribing physician passed away on May 15th.
Answer: The pharmacist should not dispense further refills, as the prescriber-patient relationship and the prescription are legally void.
A prescription's validity is predicated on a legitimate patient-prescriber relationship. This relationship terminates upon the death of the prescriber. Therefore, the original prescription and any remaining refills become void. While some states may have provisions for an emergency supply, the most accurate legal answer is that the prescription is no longer valid.
- A tourist from Canada presents a prescription for insulin glargine written by their physician in Toronto. The patient is running out of medication and needs one vial to last until they return home.
Answer: The prescription is invalid because the prescriber is not licensed to practice within a state or territory of the United States.
For a prescription to be valid in the United States, it must be issued by a practitioner licensed by a jurisdiction within the U.S. (a state, territory, or the District of Columbia). Prescriptions from foreign countries, including Canada and Mexico, are not valid and cannot be legally filled.
- On April 10th, a prescriber issues a patient three separate prescriptions for methylphenidate ER, each for a 30-day supply. Prescription #1 is dated April 10th. Prescription #2 is also dated April 10th with a note 'Do not fill before May 10th.' Prescription #3 has an issue date written as June 10th.
Answer: Prescriptions #1 and #2 are valid, but Prescription #3 is an invalid post-dated prescription.
Federal law allows practitioners to issue multiple prescriptions for a Schedule II controlled substance on the same day, authorizing up to a 90-day supply. Each prescription must be dated with the actual date of issue. The prescriber may write 'do not fill until' instructions on subsequent prescriptions. A prescription dated with a future date (post-dated) is not a valid prescription.
- A pharmacist receives a prescription from a veterinarian for 'Fido Smith' for phenobarbital 30 mg #60. The prescription includes the veterinarian's information but is missing the owner's full name and address.
Answer: The prescription is invalid until the pharmacist clarifies and documents the full name and address of the animal's owner.
For a veterinary prescription, especially for a controlled substance, federal law requires the prescription to contain the full name and address of the animal's owner, as well as the species of the animal. Dispensing the prescription without the owner's information would render it invalid.
- A pharmacist receives a new e-prescription for amlodipine 10mg with the directions 'Use as directed.' The patient has never taken this medication before and is unsure how the doctor wanted them to take it.
Answer: The prescription is not valid for dispensing until the pharmacist contacts the prescriber to obtain specific directions for use.
Directions for use are a required component of a prescription. Vague instructions like 'use as directed' are considered ambiguous and unsafe, especially for a new medication, as they can lead to patient confusion and dosing errors. The pharmacist has a professional obligation to clarify the instructions with the prescriber before dispensing to ensure patient safety and create an accurate prescription label.
- A pharmacist receives an e-prescription for oxycodone 5 mg, quantity #40, from a Physician Assistant (PA). The prescription includes the PA's name, electronic signature, and individual DEA number, but omits the supervising physician's name.
Answer: The validity depends on state-specific laws regarding requirements for supervising physician information on a PA's prescription.
Federal law allows mid-level practitioners to prescribe controlled substances if authorized by their state. However, states have varying requirements regarding the inclusion of the supervising physician's name and/or DEA number on the prescription. Therefore, the validity of this prescription is contingent upon the laws of the specific state where the pharmacy is located.
- A physician, who is a regular patient at the pharmacy, presents a prescription for zolpidem (C-IV) that she has written for herself. The prescription is otherwise complete and appears to be for a legitimate medical purpose.
Answer: The pharmacist should not fill the prescription, as self-prescribing controlled substances is generally considered unprofessional conduct.
While federal law may not explicitly forbid self-prescribing controlled substances, it is widely viewed as unprofessional conduct by medical boards and the American Medical Association. A valid prescription requires a legitimate patient-prescriber relationship, which is compromised in self-prescribing. Many states have specific regulations prohibiting it, making such a prescription invalid.
- A pharmacist receives a new prescription for alprazolam 1 mg #60 with 2 refills for a patient from a dentist. The dentist's office states it is for the patient's 'dental anxiety.' The patient's profile shows no history of anxiety medications.
Answer: The pharmacist should refuse to fill the prescription as the quantity and refills are inconsistent with legitimate use for short-term dental procedures.
While prescribing a small quantity of an anxiolytic for use immediately prior to a procedure is within a dentist's scope, a prescription for 60 tablets with 2 refills is excessive and raises a red flag regarding legitimate medical purpose. Under their corresponding responsibility, the pharmacist should recognize this as potentially illegitimate and refuse to fill it.
- A patient on vacation from another state presents a valid, written prescription for morphine sulfate ER from a prescriber licensed and practicing in their home state. The prescription meets all federal requirements. The pharmacist is not familiar with the prescriber.
Answer: The pharmacist may fill the prescription after exercising due diligence to verify the prescriber's credentials and the prescription's legitimacy.
There is no federal prohibition on filling an out-of-state C-II prescription. While state laws may vary, it is generally permissible if the prescription is valid and the pharmacist fulfills their corresponding responsibility. This includes verifying the prescriber is licensed and registered with the DEA and ensuring the prescription is for a legitimate medical purpose. It does not require a call to the out-of-state board or demand for medical records.
- A pharmacist receives an otherwise valid written prescription for fentanyl patches, but the prescriber omitted the quantity to be dispensed. The pharmacist calls and speaks directly with the prescriber, who clarifies the intended quantity.
Answer: The pharmacist must require the prescriber to send a new, complete written or electronic prescription.
According to DEA policy, the essential elements of a C-II prescription that cannot be changed or added by a pharmacist (even after consultation) are the patient's name, the controlled substance prescribed (except for generic substitution), and the prescriber's signature. Many states and the DEA consider drug strength and quantity to be among these essential elements. Therefore, the pharmacist cannot add the quantity; a new, valid prescription is required.
- A patient drops off a written prescription for hydrochlorothiazide. The prescription is on the provider's official pad and contains all required information, but the prescriber forgot to sign the signature line.
Answer: The prescription is invalid until it is signed by the prescriber, and it cannot be dispensed.
A prescriber's signature is a fundamental legal requirement for a written prescription to be valid. An unsigned prescription is not a legal order. The pharmacist cannot 'fix' this by documenting a phone call or signing on behalf of the prescriber. The prescription must be properly signed by the prescriber, or a new valid prescription must be obtained.
- A local dermatology clinic sends a written prescription to a community pharmacy for 'Compounded Magic Mouthwash, 1000 mL. For office use.' The prescription is signed by a physician at the clinic.
Answer: The prescription is invalid; pharmacies should sell medications for office use to a clinic via an invoice or other direct sale record.
A prescription is a patient-specific order. Medications intended for administration in a prescriber's office (office use) cannot be dispensed pursuant to a prescription. The proper mechanism for a pharmacy to provide drugs to a practitioner for office use is through a direct sale documented by an invoice, not a prescription.
