How often can you refill a controlled substance?

The frequency with which a controlled substance can be refilled depends on several factors, including the specific medication, its classification as a controlled substance, and the regulations set forth by the state's pharmacy board or other relevant regulatory body.

In general, controlled substances are classified into different schedules based on their potential for abuse and dependence, with Schedule II drugs having the highest potential for abuse and Schedule V drugs having the lowest. The frequency of refills for each schedule may vary.

Here's a general summary of refill intervals for controlled substances:

- Schedule II drugs: These are typically the most tightly controlled substances, and refills are often prohibited or strictly limited. In most cases, Schedule II drugs cannot be refilled without a new prescription from the healthcare provider.

- Schedule III and IV drugs: Refills for these drugs may be allowed at certain intervals, such as every 30 days or every 90 days. The specific timeframe will depend on state regulations and the medication's potential for abuse.

- Schedule V drugs: These drugs have a lower potential for abuse and dependence, and refills may be permitted more frequently. Refills for Schedule V drugs may be allowed for longer periods, such as every 6 months or even once per year.

It's important to note that these are general guidelines, and specific regulations may vary from state to state. Always consult with your doctor, pharmacist, or the state pharmacy board to determine the specific refill guidelines for a particular controlled substance.
