How long is a prescription valid for a controlled substance？
Under U.S. law, controlled substances fall into five categories (or schedules) under the Controlled Substances Act. Each schedule has different rules for refills and expiration.
Schedule II (e.g., oxycodone, amphetamines)
- Cannot be refilled under federal law.
- No federally defined expiration date,but most states impose stricter limits, such as30 days in Massachusetts and 6 months in North Carolina.
Schedule III & IV (e.g., tramadol, benzodiazepines)
- May be refilled up to 5 times.
- Prescriptions expire 6 months after the issue date.
Schedule V (e.g., certain cough medications)
- Rules vary by state, but many follow the same 6 month expiration and refill guidelines as Schedule III and IV.
State law on controlled substances prescription
While federal guidelines apply nationwide, many states impose shorter expiration periods or refill restrictions. A few examples:
- Massachusetts: Schedule II prescriptions expire 30 days after the issue date.
- North Carolina: Schedule II prescriptions remain valid for up to 6 months.
- California: All Schedule II–V prescriptions must be filled within 6 months. For Schedule III–IV drugs, there is a limit of 5 refills or a 120-day total supply, whichever comes first.
- Missouri: Generally follows federal rules. Schedule II prescriptions are valid for six months, and partial fills are allowed under DEA regulations.
- Iowa & New Jersey: Providers can issue multiple Schedule II prescriptions covering up to a 90-day supply, provided each prescription is separately dated with a specific “Do Not Fill Before” date.
- Florida: Initial opioid prescriptions are limited to a 3day supply, extendable to 7 days with documented medical necessity.
- New York, Louisiana, and South Carolina: Limit initial opioid prescriptions for acute pain to 7 days unless an exception is documented.
Pharmacies must follow whatever rule is stricter, federal or state. Always check your state’s specific requirements to avoid prescription issues.
What to do if your controlled substance prescription expires
If your prescription expires, either before you fill it or after you’ve used the authorized number of fills, you’ll likely need a new prescription. But, it can depend on the medications schedule.
Schedule II
If your prescription exceeds the allowed time limit set by your state, you’ll need a new prescription. Refills are not permitted.
Schedule III–V
Once the 6 month period has passed or the authorized number of refills has been used, a new prescription is required.
Electronic Prescriptions (EPCS)
Many states now require controlled substance prescriptions to be submitted electronically instead of handwritten or emailed. Non-electronic prescriptions may not be accepted.
Traveling between states
If you’re traveling, carry a valid copy of your prescription and confirm the rules in both your home state and the state where you’re traveling to, to avoid any complications.
Klarity Health makes prescription management easier by offering electronic prescribing and streamlined renewals when appropriate.
Tips to avoid expiring controlled substance prescriptions
The easiest way to ensure you don’t run out of your medication, especially if it’s a controlled substance, is by staying on top of your prescription limits and expiration. You can:
- Set calendar reminders based on your state’s refill limits.
- Track your refill history to avoid running out.
- Check with your pharmacist if you’re unsure when your prescription expires.
- Ask your provider to submit prescriptions electronically when possible.
- Book timely follow-up appointments to ensure uninterrupted care.
Can someone else pick up my controlled substance prescription?
Yes,but it’s more regulated than picking up non-controlled medications:
- The person collecting must provide your name, address, birthdate, and possibly ID.
- Pharmacies may call you to confirm authorization.
- Some establishments allow authorized representatives via Power of Attorney or HIPAA-compliant authorizations, but policies vary widely.
Before sending someone to collect your medication, call the pharmacy to confirm their requirements.
Controlled substance expiration dates can be tricky
How long a controlled substance is valid for depends on several factors.
- Schedule II prescriptions cannot be refilled and are subject to state-specific expiration limits (often 30–180 days).
- Schedule III–IV prescriptions are valid for 6months and may be refilled up to 5times.
- Schedule V rules vary by state, but many follow the 6month refill window.
- State regulations may override federal guidelines if they are stricter.
- Once a prescription expires or refill limits are reached, a new prescription is required.
- Plan ahead using reminders and pharmacy support to avoid lapses in treatment.
