What is the expiration date for a Schedule II prescription after being written?

The expiration date for a Schedule II prescription after being written is 6 months. This rule is in place because Schedule II controlled substances are classified under strict regulations due to their potential for abuse and dependency. The 6-month validity period ensures that the prescription reflects the most current medical necessity and patient status.

In other contexts, prescriptions for other schedules may have different expiration periods (for instance, Schedule III to V may be valid for up to six months), but for Schedule II specifically, that timeframe is generally accepted and enforced. It is important for pharmacists and healthcare providers to remain aware of these regulations to prevent dispensing errors and ensure adherence to the law.
