What to know before switching from semaglutide to tirzepatide
| Question | Answer |
|---|---|
| Is there a conversion chart? | No official one: neither label turns one medicine’s dose into the other’s |
| Tirzepatide’s starting dose? | 2.5 mg once a week for 4 weeks, then 5 mg, on the Zepbound label |
| How does the dose go up? | In steps of 2.5 mg, at least 4 weeks apart, up to 15 mg |
| When’s the first tirzepatide dose? | When your provider says. Neither label sets a waiting time, and you don’t take both |
| Side effects? | Mostly stomach side effects, mainly while the dose is going up |
| Compounded tirzepatide at NexLife? | $139 a month on the 12-month plan, or $169 month to month, at every dose |

Key takeaways
- No official conversion chart: the Zepbound label starts everyone at 2.5 mg a week for 4 weeks. Your provider decides your dose.
- Steps of 2.5 mg follow, at least 4 weeks apart, up to 15 mg. Online conversion charts are estimates.
- Don’t take both. Semaglutide’s half-life is about a week, so your provider sets the day of your first tirzepatide dose.
- Stomach side effects are the ones to expect. On the Zepbound label, most came while the dose was going up.
- Tirzepatide usually costs more. At NexLife, it’s $20 to $30 a month above compounded semaglutide, depending on the plan.
- At NexLife, compounded tirzepatide costs the same at every dose: $139 a month on the 12-month plan, or $169 month to month.

The labels
What do the labels say about starting tirzepatide?
The Zepbound label (revised August 2026) has one starting dose for every use: 2.5 mg once a week for 4 weeks, then 5 mg. It has no separate start for people coming from semaglutide. Your provider decides your dose from your history and how you did on semaglutide, then steps it up from there.
Start: 2.5 mg
Once a week for 4 weeks. The label calls it a dose for starting treatment, not one to stay on.
Then 5 mg
After those 4 weeks. 5 mg is the first maintenance dose.
Steps of 2.5 mg
If your provider raises it, after at least 4 weeks on each dose: 7.5, 10, 12.5 and then 15 mg, the maximum.
A dose that fits you
The maintenance doses are 5, 10 or 15 mg. If one doesn’t agree with you, the label says to consider a lower one.
Lilly says the same to people switching. On its LillyDirect pharmacy page, Lilly answers “which dose should I start on?” for people coming from another medication. The recommended starting dose is 2.5 mg, and if you’re switching, talk to your provider about the right approach for you.
Mounjaro starts there too. Mounjaro, tirzepatide for type 2 diabetes, also starts at 2.5 mg once a week. Both labels say the slow steps lower the risk of stomach side effects.
The two schedules, side by side
Wegovy (semaglutide)
0.25 mg for 4 weeks, then 0.5, 1 and 1.7 mg, 4 weeks each. Maintenance: 1.7 or 2.4 mg, with up to 7.2 mg after 4 weeks at 2.4 mg.
Zepbound (tirzepatide)
2.5 mg for 4 weeks, then 5 mg. After that, 2.5 mg steps, at least 4 weeks apart. Maintenance: 5, 10 or 15 mg.
Each medicine’s own label schedule (Wegovy, revised June 2026; Zepbound, revised August 2026). Side by side doesn’t mean equal: neither label says a dose of one matches a dose of the other.
Conversion charts
Is there a semaglutide-to-tirzepatide conversion chart?
Not an official one. Neither FDA label converts one medicine’s dose into the other’s, and the two work differently: tirzepatide acts on GIP and
Online charts are estimates. Some clinics publish tables that pair a semaglutide dose with a tirzepatide dose. They aren’t from the FDA labels, and they can’t tell you how your body will take a new medicine.
Your provider weighs these instead
- Your current semaglutide dose, in milligrams, and how long you’ve been on it
- How you’ve done on it: side effects, and whether your weight is still changing
- When you took your last dose
- Your health history and other medicines
- The label’s starting dose of 2.5 mg
Why going slow matters. The FDA says it has received reports of side effects that may be linked to compounded semaglutide or tirzepatide at higher doses than the approved labels allow. That includes doses raised faster than the labels’ schedules. Some people reported seeking medical care.
Why switch
Why do people switch from semaglutide to tirzepatide?
Four reasons come up most: results, a stall, side effects and price. In the SURMOUNT-5 trial (2025), average loss at 72 weeks was 20.2% on tirzepatide and 13.7% on semaglutide; it studied FDA-approved Zepbound and Wegovy, not compounded versions. A switch is a new prescription, so your provider weighs it with you.
Results in the head-to-head trial
In SURMOUNT-5, adults with obesity lost 20.2% of their body weight on average over 72 weeks on tirzepatide, versus 13.7% on semaglutide. The trial compared starting each medicine; it didn’t test switching. More: tirzepatide vs. semaglutide.
A stall
If your weight has stopped changing, your provider may look at your dose, your routine or a different medicine. Switching is one option, not the only one.
Side effects
Both medicines most often cause stomach side effects. A switch doesn’t promise fewer, and tirzepatide starts with its own dose steps.
Price
Compounded tirzepatide usually costs more than compounded semaglutide. The cost section below has the numbers.
SURMOUNT-5 (The New England Journal of Medicine, 2025) studied FDA-approved Zepbound and Wegovy at the highest dose each person could take. Compounded tirzepatide and semaglutide weren’t studied.
Doing well on semaglutide? Then there’s no need to switch. A licensed provider can help you weigh it.
Timing
When do you take your first tirzepatide dose after semaglutide?
When your provider says. Neither label sets a waiting time for switching. Both say not to take the two medicines together, and semaglutide’s half-life is about a week, per the Wegovy label (revised June 2026). Ask your provider for the day and the dose before your next shot.
Not on top of semaglutide
The Zepbound label says not to use tirzepatide with any
GLP-1 medicine. The Wegovy label says the same about semaglutide.Semaglutide lingers
Its half-life is about a week, per the Wegovy label. Some is still in your body for weeks after your last shot.
Your provider sets the day
Neither label gives a waiting time for switching. Your provider tells you when to take your first tirzepatide dose, and at what dose.

Step by step
How do you switch from semaglutide to tirzepatide, step by step?
No official chart converts one medicine’s dose into the other’s, so a switch follows your provider’s plan and the Zepbound label’s dose steps.
- Note your semaglutide dose. Write down your dose in milligrams, not units, your last dose date, how long you’ve been on it and any side effects. Compounded vials come in different strengths, so the same number of units can be a different dose.
- See a licensed provider. A switch is a new prescription. Your provider reviews your history and decides whether tirzepatide is right for you, and at what dose.
- Don’t take both. Keep taking semaglutide as prescribed until your provider confirms your next step. Each label says not to combine its medicine with another GLP-1, and semaglutide’s half-life is about a week.
- Start on the day your provider sets. Neither label sets a waiting time for switching. The Zepbound label starts everyone at 2.5 mg once a week for 4 weeks, then 5 mg; your provider decides your dose.
- Step up only as your provider directs. The label’s steps are 2.5 mg, at least 4 weeks apart, up to 15 mg. Most stomach side effects came while the dose was going up, so tell your provider how each dose agrees with you.
From your last semaglutide dose to each tirzepatide step, your provider sets the day and the dose.
In their words
What do the Zepbound label and the FDA say about switching to tirzepatide?
The exact words behind this page’s advice: where the label starts you, why going slow matters and why you don’t take both.
The label has no separate start for people coming from semaglutide. Your provider decides your dose from there.
“The recommended starting dosage of ZEPBOUND for all indications is 2.5 mg injected subcutaneously once weekly for 4 weeks.”
Eli Lilly and Company, Zepbound (tirzepatide) prescribing information, revised August 2026
Online charts that pair doses are estimates. Why going slow matters, in the FDA’s words:
“Additionally, the agency has received adverse event reports that may be related to patients prescribed compounded semaglutide or tirzepatide products in doses beyond what is in the FDA-approved drug label.”
U.S. Food and Drug Administration, FDA’s Concerns with Unapproved GLP-1 Drugs Used for Weight Loss
Semaglutide is a GLP-1 medicine, so a switch means one at a time. The Wegovy label says the same from its side.
“ZEPBOUND contains tirzepatide. Coadministration with other tirzepatide-containing products or with any glucagon-like peptide-1 (GLP-1) receptor agonist is not recommended.”
Eli Lilly and Company, Zepbound (tirzepatide) prescribing information, section 1, revised August 2026
Side effects
Will you have more side effects after switching to tirzepatide?
Maybe at first. Stomach side effects are the most common with both medicines, and they mostly come while a dose is going up. In Zepbound’s 72-week trials, nausea affected 25% to 29% of people, versus 8% on placebo; compounded tirzepatide wasn’t studied. If a dose doesn’t agree with you, your provider can hold it longer.
What the Zepbound label shows. In its two 72-week trials, nausea affected 25% to 29% of people on tirzepatide, versus 8% on placebo. Most nausea, vomiting and diarrhea happened while the dose was going up, and decreased over time. These trials studied FDA-approved Zepbound; compounded tirzepatide wasn’t studied.
In the head-to-head trial, stomach side effects were the most common in both groups. Most were mild to moderate and came mainly while doses were rising.
If a dose doesn’t agree with you, your provider can keep you on it longer or lower it. Small meals, stopping when you feel full and sipping fluids can help. Here’s more on tirzepatide side effects.
On birth control pills? The Zepbound label says tirzepatide can make them less effective. Switch to a non-oral method, or add a barrier method such as condoms. Do it for 4 weeks after you start, and for 4 weeks after each dose increase.
Severe stomach pain that won’t go away? Stop the medicine and call your provider right away: the label says it can be a sign of pancreatitis. For other questions, call or text us 24/7.

Brand-name Zepbound climbs with the dose. At LillyDirect it’s $299 at 2.5 mg, $399 at 5 mg and $449 from 7.5 mg, per 28 days (checked November 1, 2026). The $449 needs a refill within 45 days; otherwise it’s $499 at 7.5 mg and $699 at 10 to 15 mg. A first 12 weeks from 2.5 to 7.5 mg costs $1,147.

Give your dose in milligrams, not units. Compounded vials come in different strengths, so the same number of units can be a different dose. Here’s how milligrams turn into units: our tirzepatide dosage chart.
Vial math
How many units is your semaglutide dose?
It depends on your vial’s strength. Here are the Wegovy label’s dose steps at two example strengths.
| Weeks | Weekly dose | At 2.5 mg/mL | At 5 mg/mL |
|---|---|---|---|
| 1 to 4 | 0.25 mg | 0.1 mL (10 units) | 0.05 mL (5 units) |
| 5 to 8 | 0.5 mg | 0.2 mL (20 units) | 0.1 mL (10 units) |
| 9 to 12 | 1 mg | 0.4 mL (40 units) | 0.2 mL (20 units) |
| 13 to 16 | 1.7 mg | 0.68 mL (68 units) | 0.34 mL (34 units) |
| 17 onward | 2.4 mg | 0.96 mL (96 units) | 0.48 mL (48 units) |
The math: mL = dose ÷ strength (mg per mL); units = mL × 100. At 2.5 mg/mL, 1 mg is 1 ÷ 2.5 = 0.4 mL, or 40 units. At 5 mg/mL, the same 1 mg is 0.2 mL, or 20 units.
Both strengths are examples only. The same dose is a different number of units at a different strength, so read the strength on your own vial’s label. Your prescription sets your dose and schedule, which may differ from these label steps. Every step: the semaglutide dosage chart.

Switching to tirzepatide: your questions
Fair questions about NexLife
- Will my price go up with my dose?

- Do I need insurance?
- No. Pay with an HSA or FSA card, or with Affirm, Klarna or Afterpay at checkout.
What dose of tirzepatide should I start after semaglutide?
The Zepbound label’s starting dose is 2.5 mg once a week for 4 weeks. It doesn’t give a different start for people coming from semaglutide. Your provider decides, based on your current dose, how you’ve done on it and your health history.
How long should I wait after my last semaglutide shot?
Neither label sets a waiting time, so your provider tells you the day. Don’t take the two together: each label says not to combine it with another
Is 1 mg of semaglutide the same as 5 mg of tirzepatide?
There’s no official way to say so. They’re different medicines: tirzepatide acts on GIP and
Will I have more side effects after switching?
You may at first. With both medicines, stomach side effects are the most common and mostly come while the dose is rising. In the Zepbound trials, nausea affected 25% to 29% of people, versus 8% on placebo; those trials studied FDA-approved Zepbound, not compounded tirzepatide.
Can I switch from compounded semaglutide to compounded tirzepatide?
Yes, with a new prescription. A licensed provider reviews your history and decides whether it’s right for you. Compounded tirzepatide isn’t FDA-approved, and a provider prescribes it only when it offers a significant difference for you. At NexLife, it’s $139 a month on the 12-month plan, or $169 month to month, at every dose.
Does tirzepatide cost more than semaglutide?
Usually, yes. In our
Can I switch from tirzepatide back to semaglutide?
Yes, with a new prescription and your provider’s review. The Wegovy label starts semaglutide at 0.25 mg once a week, with steps every 4 weeks, and there’s no official conversion that way either. At NexLife, compounded semaglutide is $119 a month on the 12-month plan, or $139 month to month, at every dose.
Will tirzepatide work if semaglutide stopped working?
No trial has tested that: SURMOUNT-5 compared people starting each medicine, not people switching. In that trial, average loss at 72 weeks was 20.2% on tirzepatide and 13.7% on semaglutide; it studied FDA-approved Zepbound and Wegovy, not compounded versions. Your provider can weigh a switch against other options, such as a dose change.
Does tirzepatide affect birth control pills?
It can. The Zepbound label says tirzepatide can make birth control pills less effective. Switch to a non-oral method, or add a barrier method such as condoms. Do it for 4 weeks after you start, and for 4 weeks after each dose increase. Ask your provider which option fits you.
Should I switch to tirzepatide if semaglutide is working?
There’s no need to. If you’re doing well on semaglutide, a licensed provider can help you weigh a switch, which is a new prescription. If your weight has stopped changing, your provider may look at your dose, your routine or a different medicine: switching is one option, not the only one.
Will NexLife match my semaglutide price if I switch to tirzepatide?
No. The Price Match Guarantee† is like for like: it matches tirzepatide with tirzepatide and semaglutide with semaglutide, so a semaglutide price from another provider isn’t matched on tirzepatide. At NexLife, compounded tirzepatide is $139 a month on the 12-month plan, or $169 month to month, at every dose.
How much does Zepbound cost if I switch from semaglutide?
At LillyDirect, Zepbound is $299 at 2.5 mg and $399 at 5 mg per 28 days, and $449 from 7.5 mg with a refill within 45 days; otherwise it’s $499 at 7.5 mg and $699 at 10 to 15 mg (checked November 1, 2026). Compounded tirzepatide isn’t FDA-approved; Zepbound is.
Important safety information
Compounded tirzepatide and semaglutide are not FDA-approved, and the FDA hasn’t reviewed them for safety, effectiveness or quality. A provider prescribes them only when they offer a significant difference for you compared with an FDA-approved product. Both medicines may cause thyroid tumors, including cancer: don’t use either if you or a family member has had medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).
Read the full safety information
In studies with rodents, both medicines caused thyroid tumors; it isn’t known whether they cause them in people. Tell your provider if you notice a lump or swelling in your neck, hoarseness, trouble swallowing or shortness of breath. Serious side effects can include inflammation of the pancreas (pancreatitis), gallbladder problems, low blood sugar (especially with insulin or sulfonylureas), kidney problems from dehydration, severe stomach problems, serious allergic reactions, vision changes in people with type 2 diabetes, and a faster heart rate. Tell your care team before any surgery or procedure that uses anesthesia or deep sedation. Don’t combine either medicine with other
Tirzepatide can make birth control pills less effective: switch to a non-oral method, or add a barrier method such as condoms, for 4 weeks after you start and for 4 weeks after each dose increase. Both medicines may harm an unborn baby. Semaglutide should be stopped at least 2 months before a planned pregnancy. Tell your provider right away if you’re pregnant, planning to be, or breastfeeding.
