If you have been prescribed Wegovy or Mounjaro for weight management, you will have noticed that your treatment does not begin at full strength.
Instead, you start at a low dose and gradually increase over several months.
This process is called titration – and understanding it is one of the most important steps you can take to get the most from your treatment whilst keeping side effects to a minimum.
What Is Titration?
Titration is the controlled, step-by-step process of increasing a medication dose over a defined period of time.
Rather than starting at the full therapeutic dose from day one, titration allows your body to adjust gradually to the medicine, reducing the risk of side effects and improving your overall experience of treatment.
For weight loss injections such as Wegovy (semaglutide) and Mounjaro (tirzepatide), titration follows a structured schedule set by the manufacturer and approved by the Medicines and Healthcare products Regulatory Agency (MHRA).
Each step of the schedule is underpinned by clinical evidence from large-scale trials, designed to identify the safest and most effective approach to dose escalation.
Why Is Titration Necessary?
Both Wegovy and Mounjaro work by mimicking natural hormones that regulate appetite.
Wegovy acts on a hormone called GLP-1 (glucagon-like peptide-1), which is released from the gut after eating and signals to the brain that you are full.
Mounjaro goes a step further, targeting both GLP-1 and a second hormone called GIP (glucose-dependent insulinotropic polypeptide), making it a dual-agonist.
These hormonal effects are powerful.
Starting at the full therapeutic dose immediately would overwhelm many patients with side effects – most commonly nausea, vomiting, and diarrhoea.
Gastrointestinal symptoms are the most frequently reported reactions to both medicines, and they are directly linked to how quickly the body adapts to increased hormone signalling.
Titration works by giving your digestive system and appetite-control pathways time to adjust.
As each dose level becomes well tolerated, the dose is increased until you reach your maintenance dose – the level at which the medicine is most effective for long-term weight management.
Patients who follow a gradual titration schedule experience fewer side effects, are less likely to discontinue treatment early, and achieve better long-term clinical outcomes than those who escalate too quickly.
The Wegovy Titration Schedule
Wegovy (semaglutide) follows a five-stage titration schedule. Each stage lasts four weeks, giving your body adequate time to adapt before the next dose increase.
| Stage | Weekly Dose | Duration |
|---|---|---|
| Stage 1 | 0.25 mg | Weeks 1–4 |
| Stage 2 | 0.5 mg | Weeks 5–8 |
| Stage 3 | 1.0 mg | Weeks 9–12 |
| Stage 4 | 1.7 mg | Weeks 13–16 |
| Stage 5 (Maintenance) | 2.4 mg | Week 17 onwards |
The 0.25 mg starting dose is not a therapeutic dose – it is there purely to help your body adjust. Most patients do not notice significant appetite suppression at this level.
As the dose increases over the following months, the effects on hunger, satiety, and food cravings become progressively more pronounced.
Note: In some cases, a higher dose of 7.2 mg may be clinically appropriate for eligible patients in the UK and can be prescribed under medical supervision. Speak to your prescriber if you have questions about higher-dose options.
The Mounjaro Titration Schedule
Mounjaro (tirzepatide) uses a six-stage titration schedule, again with four weeks at each dose before escalation. The starting dose is designed for tolerability, not weight loss effect.
| Stage | Weekly Dose | Duration |
|---|---|---|
| Stage 1 | 2.5 mg | Weeks 1–4 |
| Stage 2 | 5.0 mg | Weeks 5–8 |
| Stage 3 | 7.5 mg | Weeks 9–12 |
| Stage 4 | 10.0 mg | Weeks 13–16 |
| Stage 5 | 12.5 mg | Weeks 17–20 |
| Stage 6 (Maintenance) | 15.0 mg | Week 21 onwards |
Not every patient will need to reach the maximum 15 mg maintenance dose.
Many achieve meaningful, sustained weight loss at 10 mg or 12.5 mg.
Your prescribing team will review your progress at each stage and advise whether continuing to escalate is appropriate for you, based on your results and how well you are tolerating the treatment.
What Happens If You Experience Side Effects During Titration?
Some nausea, particularly in the early weeks and after each dose increase, is common and expected.
In most cases, symptoms are mild to moderate and resolve within a few days as your body adjusts. There are practical steps that can help:
- Eat smaller, lower-fat meals – large or fatty meals are more likely to trigger nausea
- Avoid lying down immediately after eating
- Stay well hydrated throughout the day
- Inject on the same day each week to maintain a consistent routine
- Take your injection in the evening if morning nausea is a particular problem
If side effects at a given dose are significant, your prescriber may recommend remaining at your current dose for an additional four weeks before stepping up.
This is not a setback – it is a sensible, clinically appropriate decision that protects your long-term progress.
If you experience severe or persistent symptoms – including vomiting that prevents you from keeping fluids down, severe abdominal pain, or any signs of an allergic reaction – contact your prescriber or seek medical attention promptly.
Can You Skip or Speed Up the Titration Schedule?
No.
Titration schedules are not arbitrary timelines. Every stage has been set on the basis of clinical trial data to balance efficacy with patient safety.
Skipping stages or increasing your dose faster than recommended significantly increases the risk of side effects and may force you to reduce the dose or stop treatment altogether – the opposite of what you are trying to achieve.
Similarly, if you miss a dose, do not double up to compensate.
If fewer than five days have passed, take the missed dose as soon as you remember and continue your usual schedule.
If more than five days have passed, skip that dose and continue from your next scheduled injection. Consult your prescriber if you have missed several doses or are unsure how to restart.
A useful principle in weight management medicine is this: slower is often faster.
Patients who follow the titration schedule consistently, manage early side effects with practical strategies, and resist the temptation to rush tend to achieve the best long-term outcomes.
When Should You Seek Advice From Your Prescriber?
You should contact your prescribing team if any of the following apply:
- Side effects are severe or are not improving after the first week at a new dose level
- You have missed multiple consecutive doses and are unsure how to restart safely
- You are not noticing any reduction in appetite or food cravings after reaching 1.0 mg on Wegovy or 7.5 mg on Mounjaro
- You are considering stopping treatment – do not stop without first speaking to your prescriber
- You have any concerns about other medications you are taking alongside your injection
Both Wegovy and Mounjaro are prescription medicines that require clinical supervision throughout treatment. Please do not make changes to your titration schedule independently.
Making the Most of Your Treatment
Titration is not an obstacle to work around as quickly as possible – it is a fundamental part of how these medicines work safely and effectively.
Starting low and increasing gradually gives your body the best chance of adapting, keeps side effects manageable, and lays the groundwork for sustainable, long-term weight loss.
Weight loss injections are most effective when used alongside a reduced-calorie diet, regular physical activity, and ongoing clinical support. If you have questions about your current dose, your escalation schedule, or how to manage any side effects you are experiencing, speak to your prescribing team.
