Mounjaro (tirzepatide) uses a gradual titration schedule, starting at 2.5 mg and potentially increasing to 15 mg. But how do you know when it's the right time to step up? Here's what to consider.
The Standard Titration Timeline
The recommended approach is to increase your dose every four weeks, moving through the available doses sequentially. However, this timeline isn't set in stone — your prescriber may adjust it based on how you respond.
Signs You May Be Ready to Increase
Your prescriber will consider several factors when deciding whether to increase your dose:
- Appetite returning to pre-treatment levels — if you find your hunger has crept back and you're eating larger portions again
- Weight loss has plateaued — a stall lasting several weeks at your current dose may suggest you've adapted
- Blood sugar targets not being met — for type 2 diabetes patients, insufficient HbA1c reduction may indicate a higher dose is needed
- Good tolerability — you're managing any side effects well at your current dose
Signs You Should Stay at Your Current Dose
Increasing isn't always the right move. Your prescriber may recommend staying put if:
- You're still experiencing significant side effects — persistent nausea, vomiting, or diarrhoea suggests your body hasn't fully adjusted
- You're achieving good results already — if your weight is declining steadily and blood sugar is well controlled, a higher dose may not be necessary
- You've recently been unwell — illness, dehydration, or other health changes may warrant a pause in titration
Can You Skip Doses?
You should never skip a dose level — for example, jumping from 5 mg to 10 mg. The intermediate doses (7.5 mg and 12.5 mg) exist to help your body adjust gradually. Skipping increases the risk of severe gastrointestinal side effects and is not recommended by UK prescribers.
What If You Don't Want to Go Higher?
There's no obligation to reach 15 mg. Many patients find their optimal balance at 5 mg or 10 mg. If you're happy with your progress and tolerating your current dose, discuss staying at that level with your prescriber. The goal is the lowest effective dose that meets your treatment objectives.
Practical Tips
- Keep a food and symptom diary so you can share objective data with your prescriber
- Weigh yourself weekly at the same time of day for consistent tracking
- Don't compare your titration speed to others — everyone responds differently
- If you're paying privately, note that higher doses cost more — MedsLens can help you compare pharmacy prices at each dose level
Bottom Line
Dose increases should be guided by your prescriber based on your individual response, tolerability, and treatment goals. Never self-adjust your Mounjaro dose.
