Switching to or From Zepbound or Saxenda: What to Ask Your Clinician
If you're thinking about switching from Saxenda, Zepbound or another weight management medication, the most useful thing you can do is walk into the conversation with good questions. Your clinician decides the new medication, the starting dose and the timing, based on what you've been taking, how recently, and how it went. Switching isn't as simple as trading one pen for another, and the details matter.
People switch for all kinds of reasons. Cost is a big one. So are side effects, a plateau, wanting a weekly shot instead of a daily one, or simply losing coverage. Whatever your reason, here's how to make the switch go well.
Updated October 2026.
| Medication | What it is | How often |
|---|---|---|
| Saxenda | Liraglutide, brand name | Daily injection |
| Wegovy | Semaglutide, brand name | Weekly injection |
| Zepbound | Tirzepatide, brand name | Weekly injection |
| Compounded GLP-1 | Compounded semaglutide or tirzepatide, not FDA-approved | Usually weekly |
Why switching needs a real conversation
Saxenda is liraglutide, a daily injection. Wegovy is semaglutide, given weekly. Zepbound is tirzepatide, also weekly, and it acts on two hormone receptors instead of one. Compounded semaglutide and tirzepatide are prepared by licensed compounding pharmacies and aren't approved by the FDA.
These medications differ in how often you take them, how they're dosed, and how they feel on the way up. That's exactly why there isn't a universal conversion chart you should follow on your own. A clinician looks at your current dose, when you took it last, and how your body handled it, then picks a sensible starting point. Sometimes that means starting lower than you'd expect, especially if you've been off medication for a while.
Questions to ask before you switch
"Based on what I'm taking now, where would I start on the new medication?" This gets at dosing directly. Tell them your exact current dose and how long you've been on it.
"When should I take my last dose of the old one?" Timing matters, and overlapping two medications in the same family isn't something to improvise. Ask for a clear stop date and start date.
"What side effects should I expect in the first few weeks?" Even if you tolerated your last medication well, a new one can feel different, particularly as the dose increases. Knowing what's normal and what isn't makes the first month a lot less stressful.
"What should make me call you right away?" Get a specific answer. Then make sure you actually know how to reach someone.
"How will we know if it's working?" Agree on what progress looks like and when you'll check in, so you're not guessing.
"What will this cost me every month, all in?" Ask about visits, shipping, membership fees, and whether the price goes up as your dose goes up.
Tell your clinician everything
The switch goes better when the person prescribing has the full picture. That means your full medication list, including supplements. Any side effects you had before, even mild ones. Any new diagnoses or changes in your health since you started. Whether you're pregnant, planning to be, or breastfeeding. And how many doses you've missed recently, since a gap can change where it makes sense to start.
It also helps to be honest about what you didn't like. If injections every day wore you down, say so. If cost was the reason you stopped last time, say that too. These things shape what's realistic for you long term.
If cost is why you're switching
A lot of people look at switching because brand-name medication stopped being affordable. That's a completely legitimate reason, and it's worth saying out loud to your clinician.
At Surfbound, compounded semaglutide is $169 a month and compounded tirzepatide is $219 a month. That includes the provider review, medication if prescribed, and shipping, with no membership fee. Compounded medications are not FDA-approved, and not everyone qualifies. A licensed clinician reviews your history, including what you've taken before, and decides whether treatment is appropriate and where to start. You can see everything on our pricing page.
A few things not to do
Don't split, stretch or combine leftover pens to bridge the gap between medications. Don't restart at your old dose after a break without checking with a clinician. And don't buy anything labeled "for research use only." The FDA has warned about unapproved GLP-1 products sold outside licensed pharmacies, including dosing errors and counterfeit products.

FAQ
Can I switch from Saxenda to a weekly GLP-1?
Many people do, but your clinician should decide the starting dose and timing based on your current Saxenda dose, when you last took it, and how you tolerated it.
Do I have to start over at the lowest dose when I switch?
Not always, but sometimes. It depends on the medication you're switching from and to, your current dose, and how long it's been since your last dose. This is a clinician decision.
If I want to switch from Zepbound, what options should I ask about?
Ask whether a different weekly GLP-1, a brand-name option, or compounded tirzepatide makes sense for you, and what each would cost per month all in. Bring your current dose and the date of your last injection so your clinician can plan the start.
Can I switch from Zepbound to compounded tirzepatide?
It's possible, if a licensed clinician decides it's appropriate. Compounded tirzepatide is not FDA-approved and is not considered equivalent to Zepbound, so ask your clinician how they'll handle dosing.
How do I talk to my clinician about switching to Zepbound?
Bring your current medication and dose, when you last took it, any side effects you've had, and your reason for switching, including cost. Then ask about the new starting dose, timing, side effects and total monthly cost.
