Why Your GLP-1 Dose May Restart Lower

You were on 2.4 mg in the spring. Now a new provider wants you back at 0.5 mg, and it feels like starting over. Restarts like this happen after a break in treatment or a switch to a new telehealth company. They also happen when people move between brand-name and compounded products. The one place the idea is written down is the Wegovy injection label. It says that after two or more missed weekly shots, the dose climb starts again at a lower step. The goal is to lower the risk of nausea and other stomach side effects (Wegovy Prescribing Information). The Zepbound and Mounjaro labels cover a shot that is up to four days late and say nothing about longer gaps (Zepbound Prescribing Information; Mounjaro Prescribing Information). So a restart is a judgment call, and a lower one has an upside of its own.

Who This Helps

This guide is for anyone told to start their GLP-1 back near the lowest dose. That might be after a break, a move to a new provider, or a change between brand-name and compounded options. It also helps if you have been stepping up more slowly than the standard schedule. If you are comparing providers with the GLP Winner provider survey, it shows which dose details to have ready for a first visit.

The Wegovy injection label has the only written restart rule

Wegovy is an FDA-approved medicine that contains semaglutide, a GLP-1 receptor agonist (Wegovy Prescribing Information). The weekly shot starts at 0.25 mg and steps up every 4 weeks, to 0.5 mg, then 1 mg, then 1.7 mg. A maintenance dose begins at week 17. For weight loss, the label lists 2.4 mg as the recommended maintenance dose and 1.7 mg as another option. Someone who handles 2.4 mg for at least 4 weeks and needs more weight loss can go up to 7.2 mg.

The missed-dose rules turn on timing. Miss one shot with the next one more than 2 days away, and you take it as soon as you can. If the next shot is less than 2 days away, you skip it and go back to your usual day. After 2 or more missed shots in a row, the label says to start the step-up again "at a lower dosage." The stated goal is to reduce the risk of stomach side effects. It does not name which step, so that is the prescriber's call. If a dose is hard on you, the label also says to consider waiting 4 more weeks before the next increase.

The label treats two cases differently. Wegovy tablets, sold as the Wegovy pill, have their own missed-dose rule: skip the missed tablet and take the next one the following day. And switching between the two is not a restart. Someone on 25 mg tablets can start the 2.4 mg shot the day after their last tablet. Someone on the 2.4 mg shot can start 25 mg tablets one week after their last shot.

Zepbound and Mounjaro cover a late dose, not a long break

Zepbound is an FDA-approved medicine that contains tirzepatide, which acts on two gut hormone receptors, GIP and GLP-1 (Zepbound Prescribing Information). Everyone starts at 2.5 mg a week for 4 weeks. The label says that dose "is for treatment initiation and is not approved as a maintenance dosage." After that the dose goes to 5 mg. It can rise in 2.5 mg steps after at least 4 weeks on the current dose. The maintenance doses for weight loss are 5 mg, 10 mg or 15 mg. If a maintenance dose is hard to tolerate, the label says to consider a lower one.

Miss a Zepbound dose and the label says to take it within 4 days (96 hours). After that, skip it and take the next one on your usual day. Mounjaro, the type 2 diabetes brand that also contains tirzepatide, has the same 4-day rule (Mounjaro Prescribing Information). Neither label, in its August 2026 version, gives a plan for coming back after weeks off. That gap is where your prescriber's judgment comes in.

Get started

Compounded products have no label and no restart rule

Compounded GLP-1 products are not FDA-approved, and the FDA does not review them for safety, how well they work, or quality before they are sold (FDA). They have no label, so no official restart rule either. The brand-name labels are the closest written instructions, but they were written for, and tested with, the approved products. We use them here to explain the reasoning, not as a rule for compounded doses.

Why a slower restart is meant to help your stomach

Most of the nausea, vomiting and diarrhea in the pooled Zepbound weight-loss trials happened while doses were being raised. These effects faded over time (Zepbound Prescribing Information). The Wegovy label gives the same reason for its step-up schedule, and for restarting lower after missed shots. A lower restart is the label's way of cutting that risk a second time.

The same caution applies when someone changes from one GLP-1 drug to another. A 2024 case report in Proceedings of UCLA Health describes a patient with severe stomach symptoms after a switch (Proceedings of UCLA Health). Its authors say prescribers should first consider starting the new drug at the lowest dose or a matching one. Then they can raise it slowly, especially after earlier side effects. They add that smaller portions and avoiding high-fat foods may ease symptoms. Our post on changing your GLP-1 after you reach maintenance covers that kind of switch.

A lower dose may turn out to be enough

This is a separate point from the restart. A restart step is temporary; a maintenance dose is where you stay. Both labels list lower maintenance doses as approved options. Wegovy names 1.7 mg alongside 2.4 mg (Wegovy Prescribing Information), and Zepbound names 5 mg, 10 mg and 15 mg (Zepbound Prescribing Information). Zepbound's 2.5 mg starting step is not one of them.

SURMOUNT-1 was a large Zepbound trial in adults with obesity, or who were overweight plus a weight-related condition, and no diabetes. People who stayed on 5 mg lost a mean 15% of their body weight over 72 weeks, alongside a diet and exercise program (ACC; ACG). People on 15 mg lost 20.9%, and people on placebo lost 3.1%. The top dose did more on average, and results vary from person to person. Those are maintenance results, not restart results, and how well a lower dose works for you is something to track with your prescriber.

A lower dose costs less on some self-pay plans

As of October 20, 2026, LillyDirect lists self-pay Zepbound from $299 a month for the 2.5 mg starting dose. The 5 mg dose starts at $399 (LillyDirect). The 7.5 mg to 15 mg doses start at $449 with a refill within 45 days through the Zepbound Journey Program. Otherwise they run $499 for 7.5 mg and $699 for 10 mg to 15 mg. A month is 28 days, pen needles or syringes cost extra, and eligibility terms apply.

Wegovy is priced flat. NovoCare lists the injection at $349 a month for every dose from 0.25 mg to 2.4 mg. A lower Wegovy injection dose does not cost less there (NovoCare). People new to the Wegovy savings offer or NovoCare Pharmacy pay $199 a month for 0.25 mg and 0.5 mg for 2 monthly fills through December 31, 2026. Wegovy HD 7.2 mg is $399. The pill is priced by dose: $149 for 1.5 mg, $199 for 4 mg, and $299 for 9 mg or 25 mg.

If you move from a self-pay FDA-approved medication to a compounded medication, generally your out of pocket costs will also be less regardless of the dose change.

Compounded doses are often in units, so bring the vial's strength

A 2024 FDA alert on dosing errors with compounded semaglutide said strength can vary from one compounding pharmacy to the next. FDA-approved versions are dosed in milligrams and come in standard strengths (FDA). Some compounded instructions give doses in "units," which measure liquid. The FDA said confusion between units, milliliters and milligrams may have played a part in dosing errors. The FDA's page on unapproved GLP-1 drugs raises the same dosing concern for compounded tirzepatide (FDA).

Our guide to GLP-1 dose vs. units gives the math. By our own math with that formula, on a standard U-100 syringe, 10 units from a 5 mg/mL vial holds 0.5 mg. The same 10 units from a 2.5 mg/mL vial holds 0.25 mg. A unit number on its own cannot tell a new prescriber your dose in milligrams. Without the vial's strength, it's harder to match you to the right step.

What to bring to a new prescriber

Without records, a new prescriber has mostly your memory to go on. These fill the gap:

The date of your last shot. The Wegovy restart rule turns on missed shots in a row, and the Zepbound skip rule on 4 days.
Your current prescription or pharmacy label. The FDA suggests keeping a list with each medicine's name, strength and directions, and updating it whenever a dose changes (FDA).
For a compounded vial, the strength printed on the label in mg/mL, since that is what turns units into milligrams, as well as the units you’re directed to take.

For many people who let us know what they experience, a picture of their current vial of medication is often all they need.

Some providers may also ask these questions:

Notes on side effects at each dose. The Wegovy label allows a slower climb, and the Zepbound label a lower maintenance dose, when a dose is hard to tolerate.
If you have diabetes, your recent blood sugar readings, since the Wegovy label says to check blood sugar before starting and during treatment.
Any change to the standard plan, such as split dosing or a dose below the label's steps, which our post on microdosing vs. maintenance dosing explains.

Your old clinic may hold records you don't have at home. Under HIPAA, you have the right to a copy of your medical and billing records from covered providers and health plans (HHS). These questions can generally be filled with what you have on hand, though, with your last vial. They may charge reasonable copying and mailing costs, but not a fee for finding the records.

Final Takeaway

Being told to restart lower can feel like losing ground, and the written reason behind it is narrow. The Wegovy injection label calls for a lower restart after two or more missed shots, to limit stomach side effects. No other label covers a long gap. Compounded products have no label at all, so the restart is your prescriber's call. A lower dose can still work in your favor. Lower maintenance doses are approved for Wegovy and Zepbound, and some self-pay prices fall with the dose. Bring your last dose date and your dose in milligrams, so you and your new prescriber start from the same facts.

Frequently Asked Questions

Can a new provider keep me at my current GLP-1 maintenance dose?

That is the prescriber's decision. No label requires a restart after one late or skipped dose. The Wegovy injection label calls for a lower restart after 2 or more missed shots in a row, and the Zepbound and Mounjaro labels say nothing about longer gaps. Records showing your last dose date and your dose in milligrams make the decision easier.

Do the Wegovy and Zepbound labels allow a slower GLP-1 step-up?

The Wegovy label says so directly: consider waiting 4 more weeks before the next increase if a dose is hard to tolerate. The Zepbound label moves from 2.5 mg to 5 mg after 4 weeks and says each later increase comes after at least 4 weeks on the current dose, wording that does not rule out a longer stay at one step.

Can a lower GLP-1 dose still work for me?

It can. Lower maintenance doses are FDA-approved options: the Wegovy label lists 1.7 mg alongside 2.4 mg, and the Zepbound label lists 5 mg, 10 mg or 15 mg. In the SURMOUNT-1 trial, people on 5 mg lost a mean 15% of their body weight over 72 weeks, compared with 20.9% on 15 mg. Those are maintenance results, not restart results. How well a lower dose works for you is something to track with your prescriber.
