Wegovy and Mounjaro are popular weight loss medications. Switching from Wegovy to Mounjaro dose conversion chart is a key concern for those considering a change. This article explains the transition, dosing differences, and what to expect. It uses clear language to guide you through the process.
What Are Wegovy and Mounjaro?
Wegovy contains semaglutide, a GLP-1 receptor agonist. It’s FDA-approved for weight loss in adults and some teens. Injected weekly, it reduces appetite and promotes fullness. It’s effective with diet and exercise.
Mounjaro, with tirzepatide, targets both GLP-1 and GIP receptors. It’s approved for type 2 diabetes but used off-label for weight loss. It may lead to greater weight loss than Wegovy. Both drugs require a doctor’s supervision.
Why Switch from Wegovy to Mounjaro?
Some switch due to Mounjaro’s potential for more weight loss. Clinical trials show Mounjaro users lose up to 22.5% of body weight, compared to 15% with Wegovy. Side effects or availability issues also prompt changes. Your doctor can assess if switching suits your goals.
Other reasons include cost or insurance coverage. Mounjaro may be more accessible in some areas. Personal response to medications varies. Discuss your reasons with your healthcare provider.
How the Medications Differ
Wegovy’s semaglutide targets only GLP-1 receptors. Mounjaro’s tirzepatide affects both GLP-1 and GIP receptors. This dual action may enhance weight loss and blood sugar control. Mounjaro’s mechanism makes it unique.
Wegovy’s maximum dose is 2.4 mg weekly. Mounjaro’s highest dose is 15 mg weekly. The dosing schedules and titration differ significantly. Understanding these differences helps with the transition.
Challenges of Dose Conversion
There’s no direct dose conversion between Wegovy and Mounjaro. They have different active ingredients and potencies. Switching from Wegovy to Mounjaro dose conversion chart isn’t a simple swap. Your doctor personalizes the starting dose.
Starting Mounjaro at the lowest dose (2.5 mg) is standard. This applies even if you were on Wegovy’s highest dose. The gradual approach minimizes side effects. Your doctor considers your health and response.
The Transition Process
Switching requires a structured plan. Stop Wegovy and wait at least five weeks before starting Mounjaro. This allows semaglutide to clear your system. Combining the drugs is unsafe and increases side effects.
Start Mounjaro at 2.5 mg weekly for four weeks. Your doctor may increase it to 5 mg or higher, based on tolerability. Follow their guidance closely. Never adjust doses without medical advice.
Switching from Wegovy to Mounjaro Dose Conversion Chart
No official conversion chart exists due to the drugs’ differences. However, a general guideline helps understand the transition. The table below outlines typical dosing schedules. Always follow your doctor’s recommendations.
| Wegovy Dose (mg) | Mounjaro Starting Dose (mg) | Notes |
|---|---|---|
| 0.25–2.4 | 2.5 | Begin Mounjaro at 2.5 mg after a 5-week washout period. |
| Any dose | 5 (after 4 weeks, if tolerated) | Increase gradually every 4 weeks up to 15 mg, as needed. |
| Any dose | Higher doses (7.5–15) | Only increase under doctor’s supervision based on response. |
This table is a guide, not a prescription. Individual needs vary. Your doctor tailors the dose to your health. Regular monitoring ensures safety.
Timing the Switch
Timing is critical when switching. Wegovy’s half-life is about one week, and it takes five weeks to fully leave your system. Starting Mounjaro too soon can cause adverse effects. The five-week wait is standard.
Your doctor may adjust this based on your Wegovy dose. For example, lower doses may require less time. Blood tests or symptom checks may guide the timing. Patience ensures a smooth transition.
Managing Side Effects During Transition
Both drugs can cause nausea, diarrhea, or stomach pain. These are more common when starting Mounjaro or increasing doses. The five-week break may increase appetite temporarily. Mounjaro’s effects kick in as doses rise.
Eat small, bland meals to ease nausea. Stay hydrated and avoid fatty foods. Report severe side effects to your doctor. They may adjust your dose or offer supportive treatments.
Lifestyle Support for Success
Medication alone isn’t enough. A healthy diet with vegetables, lean proteins, and whole grains boosts weight loss. Aim for 150 minutes of weekly exercise, like walking or cycling. These habits enhance Mounjaro’s benefits.
A dietitian can create a meal plan. Support groups or counseling maintain motivation. Lifestyle changes are critical during the switch. They help sustain progress from Wegovy.
Monitoring After the Switch
Your doctor will monitor your progress closely. They’ll track weight, side effects, and health markers like blood sugar. Follow-up visits are often monthly at first. Blood tests may check kidney or liver function.
Be honest about your diet and exercise. Report any changes in appetite or symptoms. Your doctor may adjust Mounjaro’s dose based on results. Regular check-ins ensure safety and effectiveness.
Reasons for Switching
Several factors drive the decision to switch. Mounjaro’s superior weight loss in trials is a common reason. Some experience fewer side effects with Mounjaro. Others face Wegovy shortages or high costs.
