How long are Schedule II prescriptions valid after the date of issuance?

The validity of Schedule II prescriptions after the date of issuance is indeed 90 days. This aligns with the regulations set forth in both federal and Illinois state law. A pharmacist can fill a Schedule II prescription within this 90-day window, ensuring that patients receive their medications in a timely manner while allowing for appropriate monitoring and control of these high-potency drugs that have a high potential for abuse.

After the 90-day period, the prescription is considered expired, and a new prescription would need to be issued by the prescriber if the patient still requires the medication. This provision is important for maintaining patient safety and ensuring the responsible prescribing of controlled substances. It helps mitigate the risk of misuse and reinforces the careful management of medications that belong to this highly regulated category.
