Can a Nurse Practitioner Prescribe Medication in Illinois?

Yes, a nurse practitioner can prescribe medication in Illinois. State law gives NPs two routes to prescriptive authority: working under a written collaborative agreement with a physician, or qualifying for full practice authority (FPA) after completing at least 4,000 clinical hours and 250 hours of continuing education following national certification. Both routes allow prescribing controlled substances in Schedules II through V, but Schedule II drugs come with extra restrictions that apply either way.¹

The Two Pathways in Plain Terms

Under the traditional route, an NP enters a written collaborative agreement with a physician who delegates prescriptive authority. The agreement lists the categories of care the NP provides and the specific medications the physician is delegating. An employment relationship between the two isn’t required.²

The physician must file notice of the delegation with both IDFPR and the Prescription Monitoring Program, and any list of prescribed controlled substances must name the specific drugs the NP is authorized to prescribe. A signed copy of the agreement stays on file at every site where the NP practices and must be available to IDFPR on request.³

Full practice authority removes the collaborative agreement altogether. To qualify, an NP files a notarized attestation with IDFPR showing at least 4,000 clinical hours in the NP’s certification area, performed in collaboration with a physician, and 250 hours of continuing education or training, all earned after national certification. Once IDFPR grants FPA status, the NP’s regular APRN license goes inactive and is replaced by an FPA license.¹

FPA doesn’t cut physicians out entirely. An FPA NP who prescribes Schedule II narcotics (mainly opioids) or benzodiazepines must still maintain a consultation relationship with a physician, discuss those patients at least monthly, and record the consultation relationship in the Prescription Monitoring Program. Unlike a collaborative agreement, this consultation relationship is not filed with IDFPR.¹

Licenses You Need Before Writing a Prescription

Before prescribing anything, an Illinois NP must complete at least 45 graduate-level contact hours in pharmacology. This applies whether the NP works under a collaborative agreement or has FPA.⁴

Controlled substances add two more steps. NPs under a collaborative agreement need an Illinois mid-level practitioner controlled substance license from the Department of Human Services. The application requires an active APRN license, the collaborating physician’s license and controlled substance license numbers, and the schedules the NP is authorized to prescribe.⁵ FPA NPs apply for a practitioner-level controlled substance license instead, since no physician is filing a delegation notice for them.⁶

Every NP prescribing controlled substances also needs a federal DEA registration. Without both the state controlled substance license and the DEA number, prescribing any controlled substance is illegal.⁷

What You Can Prescribe Under a Collaborative Agreement

The scope of what an NP prescribes under a collaborative agreement is defined by the agreement itself. It describes the categories of care and identifies the medications the physician is delegating. Illinois law also blocks certain restrictions when no employment relationship exists: the agreement cannot limit the types of patients the NP sees (within the NP’s training), restrict which insurers or government programs the NP participates in, or confine the NP to a specific geographic area within Illinois.²

Prescribing Schedule II Drugs

Schedule II drugs, which include opioids like oxycodone and stimulants like amphetamine, are where Illinois prescribing rules get strict. Both pathways face additional limits.

An NP under a collaborative agreement may prescribe Schedule II drugs only if the physician delegates that authority, and only under these conditions:

Oral, topical, or transdermal only. Injectable Schedule II drugs cannot be delegated.
Each Schedule II substance must be identified by brand or generic name in the agreement. There is no blanket Schedule II authority.
Each prescription is limited to a 30-day supply. Continuing beyond 30 days requires the collaborating physician’s prior approval.
The NP must discuss any patient receiving a Schedule II drug with the collaborating physician at least once a month.
The delegated substances must be medications the collaborating physician routinely prescribes.

³⁸

An FPA NP can prescribe Schedules II through V without a collaborative agreement, but for Schedule II narcotics and benzodiazepines the consultation relationship, monthly patient discussions, and PMP recordkeeping described earlier still apply. The oral, topical, or transdermal restriction also carries over; injectable Schedule II drugs remain off-limits.¹

One rule applies to every prescriber, not just NPs: no Schedule II prescription may be refilled. Every nonelectronic Schedule II prescription must also carry both a written and numerical notation of the quantity on the face of the prescription.⁸

Checking the Prescription Monitoring Program

Illinois requires prescribers to check the state’s Prescription Monitoring Program before writing an initial prescription for Schedule II narcotics like opioids, and to document the check in the patient’s medical record. The point is to see whether the patient is already receiving controlled substances from other providers.⁹

Three situations are exempt from the PMP consultation requirement: prescriptions tied to oncology treatment, prescriptions for palliative care, and prescriptions for a seven-day or shorter supply provided by a hospital emergency department for an acute traumatic condition.⁹

What Goes on the Prescription

An NP working under a collaborative agreement must include the collaborating physician’s name on every prescription. The physician’s signature is not required; the NP signs their own name.¹⁰

An FPA NP does not have to include a physician’s name on prescriptions. The statute is explicit that nothing in the FPA provisions requires a physician name on prescriptions written by an FPA NP, including prescriptions for Schedule II narcotics and benzodiazepines where a consultation relationship exists.¹

Prescribing by Telehealth

NPs prescribing controlled substances through telehealth follow federal DEA rules on top of Illinois law. The framework turns on whether the patient has ever had an in-person visit with the prescriber. Once there has been an in-person visit, the NP can prescribe any medication via telehealth indefinitely with no added restrictions.¹¹

Without a prior in-person visit, the rules vary by schedule. A patient can receive up to a six-month supply of buprenorphine for opioid use disorder through a telephone consultation, but further prescriptions require an in-person visit. Schedules III through V can be prescribed via telehealth to new patients under a DEA Special Registration. Schedule II drugs prescribed via telehealth to new patients require an Advanced Telemedicine Prescribing Registration and are limited to board-certified practitioners in psychiatry, hospice care, long-term care, and pediatrics.¹¹

When a Collaborative Agreement Ends

If a collaborative agreement terminates for any reason, the physician must notify IDFPR and the Prescription Monitoring Program. The NP does not have to stop seeing patients immediately. Illinois law lets the NP keep practicing for up to 90 days after the agreement ends, provided the NP seeks collaboration at a local hospital when needed and refers patients who require care beyond the NP’s training. That window exists so patient care isn’t interrupted while the NP arranges a new agreement or qualifies for FPA.²

What Happens if the Rules Are Broken

IDFPR can revoke, suspend, refuse to renew, or place a license on probation, issue a reprimand, and impose fines of up to $10,000 per violation. Exceeding the terms of a collaborative agreement or the prescriptive authority delegated by a collaborating physician is specifically listed as a ground for discipline. Practicing without a valid license can carry a civil penalty of up to $10,000 per offense.¹²
