Pharmacy A is out. Pharmacy B, two miles away, has it. The prescription is sitting in Pharmacy A's system, and the technician says it "can't be moved."
**The short answer: since August 2023, federal rules allow an unfilled electronic prescription for a Schedule II–V controlled substance, which includes every stimulant used for ADHD, to be transferred once between retail pharmacies at your request, where state law allows. The transfer must go directly between two licensed pharmacists and must stay electronic. A pharmacy may still decline, so the fallback is a cancelled original and a new prescription sent to the pharmacy with stock.**¹
What the rule requires
| Condition | Detail¹ |
|---|---|
| Which prescriptions | Electronic prescriptions for Schedule II, III, IV or V controlled substances that have not been filled |
| How many times | Once, at the patient's request |
| Who handles it | Communicated directly between two licensed pharmacists |
| Format | Stays electronic; it cannot be printed or faxed into a paper prescription |
| State law | Allowed where existing state law permits; California pharmacies act under the Board of Pharmacy's rules and their own software's capability |
A prescription that has already been partially filled is a different case, and a paper prescription cannot use this route.¹
The words to use
At the pharmacy that is out of stock: "Please transfer my unfilled electronic prescription to [pharmacy], pharmacist to pharmacist. I understand it can be transferred once."
At the pharmacy that has stock: "I am asking [pharmacy] to transfer my unfilled e-prescription to you. Can your pharmacist receive it today, and do you have [drug, strength, form] on hand?"
Write down both pharmacists' names and the time. If the transfer stalls, that record shortens the next call.
If the pharmacy says no
Some pharmacies choose not to transfer controlled-substance prescriptions, or their software does not support it. Do not argue. Message your prescriber: which pharmacy has stock, and which product and strength they have. Because Schedule II prescriptions cannot be refilled, the prescriber cancels the first prescription and sends a new one.² That is usually same-day, and it avoids two active prescriptions for the same medicine appearing in your CURES record, which California prescribers must check before prescribing and at least every six months.³
Before you ask for a transfer
Check that the problem is a local stockout rather than a national shortage. FDA's Drug Shortages database is the official list; if your exact product is on it, every pharmacy is short and a partial fill or a different strength may be the faster fix.⁴ The full six-step routine is on the refill and shortage checklist →.
Q&A
Q: Can a paper stimulant prescription be transferred? A: No. The federal transfer rule applies only to electronic prescriptions that have not been filled.¹ A paper prescription goes to one pharmacy; if that pharmacy cannot fill it, ask your prescriber for a new one.
Q: Can it be transferred a second time if the second pharmacy is also out? A: No. The rule allows one transfer.¹ After that, the prescriber sends a new prescription.
Q: Does Medi-Cal change any of this? A: The transfer rule is federal and applies regardless of payer. Medi-Cal Rx adds its own limits, including a 35-day maximum supply per controlled-substance claim, and its customer service line, 800-977-2273, can confirm coverage at the new pharmacy.⁵
