Thinking about switching from Saxenda to Mounjaro and not sure how to do it safely? You're not alone. This is one of the most underexplained GLP-1 questions online.

At FindMyGLP1.com, we use trusted evidence-based sources like the FDA and major medical journals so you can rely on us to give it to you straight. In the next few minutes, I'll cover five things. Approvals and what off label means.

How to time the switch from daily to weekly. dosage transitioning, common side effects, and smart next steps to discuss with your provider. Saxenda is liraglutide, a GLP-1 you take daily for chronic weight management.

tirzepatide is the active ingredient in two name brands. Mounjaro, which is approved for type 2 diabetes, and Zepbound, which is approved for chronic weight management. Same active ingredient, just different FDA labels.

If your goal is weight loss and your prescriber chooses Mounjaro instead of Zepbound, that's called off label use. It's legal at a clinician's discretion, but coverage and pharmacy rules can differ. Your provider will guide you on what's right for you.

Switching medications can be stressful. So, let's break down some of the confusion. Labels, dosing units, and schedules don't line up one-to-one.

So, there's no direct conversion from a Saxenda dose to a Mounjaro dose. Your prescriber will individualize the plan, but here's the framework so you can ask smart questions. Step one, know the approvals.

Saxenda is approved for weight management. Mounjaro is approved for type 2 diabetes. Zepbound is the tirzepatide brand approved for weight management.

Step two, time the change. Because Saxenda is daily and tirzepatide is weekly, your clinician will avoid medication overlap, spacing your last Saxenda dose and first weekly Mounjaro dose appropriately. Step three, how starting doses work.

Providers usually start Mounjaro at 2.5 mg once weekly for 4 weeks, then 5 milligrams weekly. Even if you were at the max Saxenda dose, it might feel deflating to start a new medication at the lowest dose. But starting low helps limit stomach side effects and let your body adjust.

Now let's go over the dosages. As the table comes on screen, remember this is not a milligram to milligram conversion chart. These are different medicines with different schedules.

You start 2.5 milligram of Mounjaro weekly regardless of your prior saxenda dose. As with most GLP-1 medications, the common side effects of Mounjaro include nausea, vomiting, diarrhea, and constipation, especially when doses increase. You can go to FindMyGLP1.com for our best tips on how to minimize these side effects.

Call your clinician if you have severe or lasting belly pain. If you notice signs of dehydration like dizziness or very dark urine or if you have diabetes, any signs of low blood sugar like sweating or shakiness, share any history of medullary thyroid carcinoma or MEN 2 with your provider before using these medicines. If cost and coverage are concerns, ask your provider about coverage for Saxenda versus other tirzepatide-based medications, any necessary prior authorizations, and any savings programs.

To wrap up, here are the big takeaways. Understand the approval landscape. Avoid overlap when switching and start at 2.5 mg weekly.
