Request your GLP-1 refill 7 to 10 days before your current supply runs out. That timing accounts for a required clinician check-in, which must happen before any pharmacy releases your next order, plus 3 to 5 business days of shipping once it ships. Waiting until you're down to a few doses is the most common cause of a treatment gap.
TL;DR:
- For a 28 to 30 day supply, start the clinical review around day 21 or 22, and count remaining weekly doses instead of calendar days.
- Clinicians usually require clinical updates every 1 to 3 months; missed updates can hold a prescription because pharmacies need current approval.
- Pharmacy verification adds 1 to 3 business days after approval, and shipping usually takes another 3 to 5 business days; contact your clinic about delays.
- Wegovy allows a missed dose if the next is over 48 hours away; Zepbound allows dosing within 96 hours, and consecutive misses may require retitration.
- Compounded semaglutide is not FDA approved; verify the product concentration, measurement units, and vial instructions with the pharmacy before using a new vial.

How GLP-1 refills work in telehealth and mail-order programs
A GLP-1 refill is a clinical decision, not an automatic reorder. Before any prescription renews, your clinician reviews how you've tolerated the medication, where your weight trend stands, whether you've had side effects, and whether new labs are needed. This review exists because dosing often changes over time, and a clinician needs current information to confirm your next supply is still the right one.
Most telehealth programs collect this information through one of three formats: a short digital assessment you complete in a patient portal, a secure message exchange with your care team, or a brief video check-in. Each format feeds the same outcome: a clinician either approves the refill as is, adjusts the dose, or asks for more information first.
Once approved, the order moves to the pharmacy, which verifies the prescription, prepares the medication, and ships it. The pharmacy doesn't act until it receives clinician sign-off, which is why a check-in delay on your end pushes everything else back. Understanding how the intake and verification process works from the start makes the refill cycle easier to anticipate.
When to request a refill: simple timing rules patients can use
The FDA's general guidance on prescription refills points to submitting requests once you're roughly 75 to 80% through your current supply, which works out to around day 21 or 22 of a typical 28 to 30 day cycle. That window leaves room for clinical review and shipping without cutting it close.
A few rules make the math simple:
- For a 28 to 30 day supply, mark your calendar for day 21 or 22 to start the check-in.
- Build in a 7 to 10 day buffer before your last dose, since review and shipping both take time.
- If you use weekly pens, count remaining doses rather than days, since a missed week throws off a day-based count.
- Add extra buffer around weekends and holidays, when clinic response times and shipping both slow down.
Step-by-step checklist: how to request your GLP-1 refill
Following the same sequence each cycle keeps refills predictable and reduces the chance of a gap.
- Check your remaining doses and set a target date. Note any upcoming travel or events that might shift when you need your next shipment.
- Complete your required check-in. Report weight change, GI symptoms, any new medications, and pregnancy plans if relevant; attach labs if your clinician has requested them.
- Submit your refill request. Use your patient portal or scheduling system and include the medication name, current dose, date of your last shipment, and preferred shipping address.
- Confirm the order has moved to the pharmacy. Ask for an expected ship date and tracking number once your clinician approves the refill.
- Track the shipment. Contact your clinic right away if delivery is late or appears lost, so an interim plan can be arranged before you run out.
Pro Tip: Set a recurring calendar reminder for day 21 of each cycle so the check-in never competes with a last-minute scramble.
Clinical check-ins and monitoring that gate refills
Most telehealth GLP-1 programs require check-ins every 1 to 3 months, with some asking for brief updates monthly or every other month. These aren't paperwork formalities. Clinicians use them to track your weight trend, note any GI side effects, review blood glucose patterns if you're diabetic, check blood pressure, flag new medications, and confirm pregnancy or breastfeeding status.
Completing these on schedule is what keeps refills moving. A missed check-in is the single most common reason a refill gets held, since the pharmacy simply cannot release medication without a current clinical sign-off. Treating the check-in as a fixed appointment, rather than an optional survey, is the habit that prevents interruptions.
Shipping, pharmacy processing, and timing expectations
Once your clinician approves a refill, the pharmacy still has to verify the prescription and prepare the order, a step that commonly adds 1 to 3 business days before anything ships. After release, shipping typically takes 3 to 5 business days in transit.
A few factors can stretch that timeline further:
- Holidays and weekends slow both clinic response times and carrier delivery.
- A required prior authorization or insurer approval step can add days before the pharmacy even begins processing.
- Pharmacy stock issues occasionally delay a specific dose strength.
If you hit any of these, contact your clinic directly and ask about an interim plan rather than waiting it out silently.
Missed doses and managing treatment gaps
The Wegovy prescribing label instructs patients to take a missed weekly dose if the next scheduled dose is more than 48 hours away, and to skip it and resume the regular schedule if it's closer than that. The Zepbound label gives a slightly longer window: administer a missed dose within 96 hours, or skip it and resume your normal schedule if more time has passed. Both labels note that consecutive missed doses may require your clinician to reinitiate treatment at a lower dose and re-titrate upward.
Never source medication outside your prescribing clinic or adjust your own dose to cover a gap. If you see a refill delay coming, ask your clinic whether a short supervised pause or an expedited reissue is the safer path, rather than trying to bridge the gap informally. Our titration and dosing schedule guide lays out how re-titration typically works if a restart is needed.
Safety notes: compounded and unapproved GLP-1 products
The FDA has warned that compounded semaglutide products can vary in concentration and packaging, and that dosing errors have occurred when patients or providers confused units with milligrams during measurement. Compounded products are not FDA-approved, which makes label clarity and pharmacy verification especially important at refill time.
One in several dosing error reports tracked by the FDA trace back to unit-to-milligram conversion mistakes with compounded injectable semaglutide, a confusion that's avoidable with a quick confirmation step at each refill. A few checks reduce that risk:
- Confirm the exact concentration and measurement unit with your pharmacy before your first dose from a new vial.
- Ask how the product was packaged and whether the vial is single-dose or multi-dose.
- For multi-dose sterile vials, confirm handling instructions, since FDA guidance generally calls for use within 28 days of first opening.
- Use a state-licensed pharmacy and report any adverse event or quality issue through FDA MedWatch.
For a deeper look at verifying a compounded product before you use it, our compounded semaglutide checklist and our patient safety checks guide walk through each step. Clinicians also monitor glucose and weight trends during check-ins partly because of how GLP-1 hormone activity affects metabolism, which is worth understanding if you're tracking your own response between refills.

FAQ
How do I refill a prescription that has no refills left?
Contact your prescribing clinic directly rather than the pharmacy, since a prescription with zero refills requires a new clinician review before the pharmacy can dispense again. In a telehealth program, this usually means completing your regular check-in so the clinician can authorize a new prescription.
How do I get approved for GLP-1 medication?
Approval requires a clinician review of your health history, current weight, and relevant labs through an online intake or in-person visit. Programs that offer ongoing clinician-led GLP-1 care build this review into the start of treatment and repeat it at each refill.
How soon is too soon to refill a prescription?
Requesting a refill when you still have more than a week of medication left is generally fine and often recommended, since it gives your clinician and pharmacy time to process the order. The guidance to request 7 to 10 days before running out exists precisely so you're not left without medication while review and shipping happen.
Can I get GLP-1 medication online for weight loss?
Yes, licensed telehealth programs in the United States can prescribe FDA-approved GLP-1 medications for weight loss after a clinician completes an online evaluation. Confirm any provider uses state-licensed pharmacies and discloses dosing and concentration clearly, especially for compounded products.
