Trulicity to Mounjaro Conversion Chart: A Simple Guide for 2025
Switching from Trulicity to Mounjaro can be a smart move for managing type 2 diabetes. Both medications help control blood sugar, but they work differently.
This article provides a clear Trulicity to Mounjaro conversion chart and explains the transition process in simple terms. By understanding dosages, benefits, and steps, you can make the switch safely with your doctor’s guidance.
What Are Trulicity and Mounjaro?
Trulicity is a weekly injection for type 2 diabetes. Its active ingredient, dulaglutide, is a GLP-1 receptor agonist that boosts insulin release and lowers blood sugar. It also reduces the risk of heart attack and stroke in some patients.
Mounjaro, with the active ingredient tirzepatide, is also a weekly injection. It’s unique because it targets both GLP-1 and GIP hormones, offering stronger blood sugar control and more weight loss.
Mounjaro is FDA-approved for type 2 diabetes but not for weight loss, though it’s often used off-label for this. Both drugs are effective, but Mounjaro’s dual action makes it a popular choice for switching. Always consult your doctor before changing medications.
Why Switch from Trulicity to Mounjaro?
Some patients switch to Mounjaro for better blood sugar control. Clinical trials, like the SURPASS-2 study, show Mounjaro reduces A1C levels more than Trulicity. It also leads to greater weight loss, which can benefit diabetes management.
Other reasons include side effects from Trulicity, like nausea, or insurance coverage changes. Mounjaro may be more effective for some, but the transition needs careful planning. A Trulicity to Mounjaro conversion chart helps ensure the right dosage.
How Do Trulicity and Mounjaro Dosages Compare?
Trulicity and Mounjaro have different dosing schedules. Trulicity starts at 0.75 mg weekly, increasing to 1.5 mg, 3 mg, or 4.5 mg as needed. Mounjaro begins at 2.5 mg weekly, then rises to 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg.
Because Mounjaro is more potent, direct milligram-to-milligram conversion isn’t possible. A conversion chart provides general guidance, but your doctor will adjust based on your health. Below is a simplified Trulicity to Mounjaro conversion chart based on typical dosing.
| Trulicity Dose (Weekly) | Mounjaro Starting Dose (Weekly) | Notes |
|---|---|---|
| 0.75 mg | 2.5 mg | Starting dose for new Mounjaro users |
| 1.5 mg | 2.5–5 mg | May start at 5 mg if well-tolerated |
| 3 mg | 5–7.5 mg | Adjust based on side effects |
| 4.5 mg | 7.5–10 mg | Higher doses for stable patients |
This chart is a guide, not a strict rule. Your doctor will consider your current dose, side effects, and health goals.
Steps to Transition Safely
Switching medications requires a clear plan. Your doctor will guide you, but here’s what to expect during the transition.
Consult Your Healthcare Provider
Start by talking to your doctor about why you want to switch. They’ll review your A1C levels, weight, and medical history. This helps determine if Mounjaro is right for you.
Stop Trulicity at the Right Time
You’ll typically stop Trulicity one week before starting Mounjaro. This aligns with Trulicity’s weekly schedule and reduces overlap. Your doctor may adjust this based on side effects.
Start Mounjaro at a Low Dose
Mounjaro usually starts at 2.5 mg weekly to minimize side effects like nausea. After four weeks, your doctor may increase to 5 mg or higher. The conversion chart helps select the starting dose.
Monitor Blood Sugar and Side Effects
Check your blood sugar regularly during the switch. Watch for side effects like diarrhea or stomach pain, which are common with Mounjaro. Report any concerns to your doctor.
Adjust Lifestyle for Best Results
Both medications work best with a healthy diet and exercise. Eating balanced meals and staying active can enhance Mounjaro’s effects. Your doctor or a dietitian can offer tips.
Benefits of Switching to Mounjaro
Mounjaro offers several advantages over Trulicity. Here are the key benefits:
- Better A1C Reduction: Studies show Mounjaro lowers A1C by up to 2.3%, compared to 1.9% for Trulicity.
- More Weight Loss: Mounjaro users lose 12–25 pounds on average, while Trulicity users lose 5–10 pounds.
- Dual Hormone Action: Mounjaro targets GLP-1 and GIP, improving blood sugar and appetite control.
- Weekly Dosing: Like Trulicity, Mounjaro is convenient with once-weekly injections.
These benefits make Mounjaro appealing, but results vary. Your doctor will monitor your progress to ensure it’s working.
Potential Challenges During the Switch
Switching medications isn’t always smooth. Mounjaro’s stronger effects can cause more side effects, especially at higher doses. Common issues include nausea, vomiting, and diarrhea, which usually fade over time.
Insurance coverage is another hurdle. Some plans cover Mounjaro, but prior authorization may be needed. Check your formulary to confirm coverage and copays.
Mounjaro’s higher cost—around $1,200 per month without insurance—can be a barrier. Manufacturer savings cards or assistance programs can help. Discuss affordability with your doctor or pharmacist.
What to Expect After Switching
After starting Mounjaro, you may notice changes within weeks. Blood sugar levels often improve, and some people lose weight early on. Side effects are most common in the first month but typically lessen.
Your doctor will check your A1C after 8–12 weeks to assess Mounjaro’s effectiveness. They may adjust your dose if needed. Regular follow-ups ensure the medication meets your needs.
Lifestyle changes, like cutting sugar or walking daily, boost Mounjaro’s benefits. A consistent routine helps maintain stable blood sugar and supports weight loss.
Who Should Consider Switching?
Mounjaro may be a good fit if Trulicity isn’t controlling your blood sugar well. It’s also an option if you want more weight loss or experience Trulicity side effects. Adults with type 2 diabetes are the primary candidates.
Mounjaro isn’t suitable for everyone. It’s not approved for type 1 diabetes or children. People with a history of pancreatitis or thyroid tumors should avoid it. Your doctor will review your health to decide.
If you’re using Trulicity for heart risk reduction, switching may not be ideal. Trulicity is FDA-approved for this, while Mounjaro isn’t. Discuss your goals with your doctor.
Tips for a Smooth Transition
Making the switch easier requires preparation. These tips can help:
- Follow Your Doctor’s Plan: Stick to the prescribed Mounjaro dose and schedule.
- Track Your Symptoms: Note any side effects or blood sugar changes in a journal.
- Use Savings Programs: Check Eli Lilly’s website for Mounjaro savings cards or assistance.
- Stay Hydrated: Drinking water can reduce nausea and other side effects.
- Be Patient: It may take weeks to adjust to Mounjaro, so give it time.
These steps can make the transition smoother and improve your results. Always keep your doctor informed.
Risks of Improper Switching
Switching without medical guidance can be risky. Starting Mounjaro at too high a dose may cause severe nausea or low blood sugar. Overlapping Trulicity and Mounjaro can increase side effects.
Using a Trulicity to Mounjaro conversion chart without a doctor’s input is dangerous. Charts are general guides, not personalized plans. Always follow professional advice.
Compounded versions of Mounjaro or Trulicity are not FDA-approved. They may be unsafe or ineffective. Stick to prescribed medications from licensed pharmacies.
Summary
Switching from Trulicity to Mounjaro can improve blood sugar control and promote weight loss for people with type 2 diabetes. The Trulicity to Mounjaro conversion chart offers a starting point, but your doctor will tailor the dose to your needs.
By following medical guidance, monitoring side effects, and maintaining a healthy lifestyle, you can transition safely. Mounjaro’s dual action makes it effective, but it’s not for everyone. Regular check-ins with your doctor ensure the switch works for you.
