Semaglutide dosage: a step-by-step titration schedule

Semaglutide does not work at full strength from day one. The semaglutide dosage schedule is deliberately structured in stages, so that your body can get used to the medicine and side effects are minimised as much as possible. In this article, you can read exactly what that titration schedule looks like, what the differences are between Ozempic and Wegovy, and what you can expect during each phase of treatment.

Why semaglutide is titrated in stages

Semaglutide stimulates GLP-1 receptors in the brain and the gastrointestinal tract. This leads to reduced hunger, slower gastric emptying and, ultimately, weight loss. It is precisely this slowing of gastric emptying that is the reason why you may experience nausea, diarrhoea or vomiting at the start. By gradually increasing the dose, the body gives itself time to get used to the effects. Clinical research shows that this titration protocol significantly reduces side effects without affecting the ultimate effectiveness.

The Wegovy titration schedule (2.4 mg per week)

Wegovy is the form of semaglutide specifically authorised for weight management. The Wegovy dosing schedule consists of five phases, spanning a total of sixteen weeks:

Phase 1 lasts for the first four weeks. You start with 0.25 mg per week. This is a starting dose intended solely to allow you to get used to the medication; no substantial weight loss is expected at this level. Phase 2, weeks five to eight, increases the dose to 0.5 mg per week. In phase 3 (weeks nine to twelve), the dose is increased to 1.0 mg, and in phase 4 (weeks thirteen to sixteen) to 1.7 mg. From week seventeen onwards, you reach the maintenance dose of 2.4 mg per week.

Each injection is administered subcutaneously, in the abdomen, the upper thigh or the upper arm. You rotate the injection sites to prevent irritation. In the STEP 1 study, participants lost an average of almost 15% of their body weight after 68 weeks on this schedule, as clinical research shows.

The Ozempic titration schedule (up to 2.0 mg per week)

Ozempic contains the same active ingredient but is authorised for type 2 diabetes mellitus, not for weight management. The schedule is slightly more compact: you start with 0.25 mg per week for four weeks, then move to 0.5 mg as a maintenance dose, and can increase to 1.0 mg and eventually 2.0 mg per week if necessary.

When is the dose increased?

The dose is not automatically increased at a fixed time. Your treating doctor will assess whether you are ready for the next step. Criteria include: how well you tolerate the current dose, whether gastrointestinal symptoms have improved, and whether sufficient weight loss is occurring. It is also possible that the doctor may decide to continue at a particular stage for longer if this is clinically advisable. The schedule is a guideline, not a strict requirement.

Real-world data shows that fewer than a quarter of people actually reach the maximum dose of 2.4 mg. Nevertheless, the majority of participants who continued for twelve months or longer achieved weight loss of over 14%, comparable to the results in controlled clinical trials. The lesson: the titration schedule is the goal, not the maximum dose.

What if you cannot tolerate the maximum dose?

Some people experience persistent nausea or vomiting at higher doses. In that case, you can continue on a lower dose in consultation with your doctor. This is not a failure of the treatment, but an adjustment to suit your body. For most people, side effects decrease as treatment continues. You can read more about what may occur with semaglutide in the overview of Ozempic side effects for weight loss. Always consult your doctor if side effects are severe or persistent.

What if you miss an injection?

If you have missed a weekly injection, you can still administer it if there are at least two days left until the next scheduled injection. If you are closer to the next injection day, skip the missed dose and continue with the normal schedule. The dose should never be doubled. If in doubt, it is advisable to contact your healthcare provider.

Semaglutide and long-term weight loss

The dosing schedule is designed for long-term use. Research into what happens after stopping semaglutide shows that, on average, people regain two-thirds of the weight they lost within a year of stopping treatment. This underlines that semaglutide is not intended as a short-term treatment, but as part of a broader lifestyle intervention. At Goodweigh, the medication is therefore always combined with coaching and medical support. Read more about the Goodweigh programme.

Am I eligible for semaglutide?

Semaglutide (as Wegovy) is approved for adults with a BMI of 30 or higher, or a BMI of 27 or higher in combination with weight-related health issues such as hypertension or sleep apnoea. Whether you are eligible depends on several factors. Read the criteria in the article on when you are eligible for GLP-1 medication. You can also start an initial consultation directly via Goodweigh: the doctor will assess your situation and draw up a treatment plan that suits you.
