How to Request a Prescription Refill From Your Doctor

What are the three ways to request a refill?

Patient portal (fastest for many practices). Log into your clinic's online portal and send a message to your care team. Include your medication name, the pharmacy you use, and how soon you will run out. Many practices triage portal messages within one business day.

Your pharmacy requests it for you. Ask your pharmacist to send an electronic refill request to your prescriber. The office then approves or denies it and you receive a text or call when it is ready. This is usually the path of least resistance for non-controlled medications.

Call the office directly. Ask for the nurse line or the prescription refill voicemail. Leave your name, date of birth, medication name, and pharmacy phone number. Avoid calling right before a long weekend or holiday if you can.

How far ahead should you request a refill?

Request when you have about seven to ten days of supply remaining. This gives the office time to process the request and the pharmacy time to fill it.

If your medication requires prior authorization from an insurance plan — common with specialty or brand-name drugs — the process can take longer, sometimes a week or more. Ask your pharmacist whether your drug has a prior authorization on file so you are not caught short.

For mail-order or 90-day supply pharmacies, request earlier still — shipping adds days to lead time.

What does your clinician need from you?

Your care team will want to confirm that you are still an active patient, that your last visit was recent enough (often within the past year for routine medications), and that the medication is still appropriate. For some conditions, a brief check-in visit or a lab result may be required before a renewal is approved 1Ref 1Agency for Healthcare Research and Quality (AHRQ) (2023).Medication Reconciliation.Clinicians require periodic check-ins and medication reconciliation before renewing prescriptions to confirm ongoing appropriateness and catch safety issues.

Have ready: the exact medication name and strength as it appears on your bottle, your pharmacy's name and phone number, how many days of medication you have left, and a list of any new medications or supplements you have started since your last visit.

When a refill alone may not be enough

Your prescriber may want to see you before renewing if your condition has changed, your last visit was more than a year ago, you are on a medication that requires monitoring (such as regular lab work), or you are on a controlled substance 2Ref 2U.S. Drug Enforcement Administration (2024).21 CFR §1306.12 — Refilling Prescriptions; Issuance of Multiple Prescriptions (Schedule II).Federal law prohibits refilling Schedule II controlled substance prescriptions; each fill requires a new authorized prescription; Schedule III–IV prescriptions may be refilled up to six months from issue date.

Controlled substances — stimulants, opioids, benzodiazepines — cannot be refilled the same way as non-controlled medications. Federal law prohibits refilling Schedule II prescriptions; each fill requires a new prescription 2Ref 2U.S. Drug Enforcement Administration (2024).21 CFR §1306.12 — Refilling Prescriptions; Issuance of Multiple Prescriptions (Schedule II).Federal law prohibits refilling Schedule II controlled substance prescriptions; each fill requires a new authorized prescription; Schedule III–IV prescriptions may be refilled up to six months from issue date. For Schedule III and IV medications (such as benzodiazepines), refills are permitted up to six months from the date of issue, but state laws may be stricter.
