Wegovy Dosing Schedule: Week-by-Week Titration Guide

The Wegovy dosing schedule is deliberately slow. Instead of starting at the dose that produced the headline weight loss in clinical trials, Wegovy (semaglutide 2.4 mg) begins at a very small dose and rises step by step over about four months. This process, called dose titration, gives your digestive system time to adjust and reduces the chance of nausea, vomiting and other gastrointestinal side effects. This guide sets out the standard schedule, explains how to read it, covers common questions and shows what to do when things do not go to plan.

This article is educational. Your prescriber decides your exact plan based on your health, tolerance and goals, and the patient information leaflet that comes with your pen always takes priority. You can learn about the medicine itself on the Wegovy product page.

The Standard Wegovy Dosing Schedule

For adults using the once-weekly Wegovy pen, the approved titration works as follows.

Treatment weeks	Weekly dose	Purpose
Weeks 1 to 4	0.25 mg	Starter dose, helps tolerance
Weeks 5 to 8	0.5 mg	First step up
Weeks 9 to 12	1 mg	Second step up
Weeks 13 to 16	1.7 mg	Third step up; often a maintenance dose
Week 17 onward	2.4 mg	Recommended maintenance dose

The Wegovy dosing schedule therefore takes 16 weeks to reach the full dose. Some people never need to reach 2.4 mg: if the 1.7 mg dose gives good results with manageable side effects, a prescriber may keep you there. The 0.25 mg dose is not meant to produce major weight loss. Its job is to prepare your body for higher doses.

How Each Wegovy Dosing Schedule Step Works

Semaglutide mimics GLP-1, a hormone that signals fullness, slows stomach emptying and helps regulate blood sugar. At the starting dose, you may feel only a slightly smaller appetite. As the dose rises, the effect on hunger and cravings grows. Our explainer on how GLP-1 injections work covers the science in plain language.

Weeks 1 to 4: 0.25 mg

Choose a day of the week that suits you and inject on the same day each week. Some people feel nothing; others notice early fullness or mild nausea. Eat small meals and stop when you feel satisfied.

Weeks 5 to 8: 0.5 mg

This is often when appetite changes become noticeable. Watch hydration and protein intake. If side effects are strong, ask your prescriber whether to stay on the current dose a little longer.

Weeks 9 to 12: 1 mg

Weight loss usually picks up here. Constipation can become more common, so increase fibre and fluids.

Weeks 13 to 16: 1.7 mg

Many people achieve meaningful results at this stage. Your prescriber reviews your progress and decides whether to move to 2.4 mg.

Week 17 onward: 2.4 mg

This is the dose used in the pivotal STEP 1 trial, where adults lost an average of around 15 percent of their body weight over 68 weeks alongside lifestyle changes, compared with about 2 percent on placebo. Individual results vary greatly.

How Often Should You Inject?

Once a week, on the same day, with or without food and at any time of day. If you need to change your injection day, you can do so as long as the gap between doses is at least three days (72 hours). Missing a dose is common, so read our guide to what to do after a missed dose. For technique, read how to inject a weight loss pen step by step.

What if Side Effects Are Too Strong on the Wegovy Dosing Schedule?

The label allows flexibility. If a dose step causes problematic symptoms, your prescriber may delay the next increase by a few weeks, return to the previous dose or hold the plan until symptoms settle. The goal is a dose you can tolerate and sustain, not the fastest possible escalation. Typical advice includes eating smaller, lower-fat meals, drinking fluids, avoiding lying down right after eating and stopping at the first sign of fullness. For further help, see what to eat on GLP-1 medication and our guide to Wegovy side effects.

Seek urgent medical care for severe, persistent abdominal pain, repeated vomiting, signs of dehydration, yellowing of the skin or eyes, or symptoms of an allergic reaction such as swelling of the face or difficulty breathing.

Wegovy Dosing Schedule vs Mounjaro Dosing Schedule

Mounjaro (tirzepatide) uses a similar principle but different steps: it starts at 2.5 mg weekly, rises to 5 mg after four weeks, and then increases in 2.5 mg steps every four weeks as needed up to 15 mg. Read the Mounjaro dosing schedule and the Mounjaro vs Wegovy comparison to see how they differ in practice.

Wegovy vs Ozempic Dosing

Both contain semaglutide, but they are approved for different uses and use different dose ladders. Ozempic, approved for type 2 diabetes, typically ranges from 0.25 mg up to 2 mg weekly. Wegovy goes up to 2.4 mg and is approved for weight management. Never substitute one for another without medical direction. Our article on the difference between Ozempic and Wegovy explains in detail.

Maintenance Dose: How Long Will You Stay on It?

Obesity is a chronic condition, so the maintenance dose is usually continued long term. Trial participants who stopped semaglutide regained a substantial portion of the weight they had lost within a year. If you plan to stop, talk to your prescriber first and review what happens when you stop taking Wegovy.

Practical Tips for Sticking to the Schedule

• Set a recurring reminder on your phone for injection day.
• Write the date and dose on a calendar or in an app.
• Rotate sites between the abdomen, thigh and upper arm.
• Store unopened pens in the fridge and follow the leaflet for in-use pens.
• Track weight weekly rather than daily, since daily fluctuations can mislead you.
• Book review calls before each step up.

Who Should Not Follow the Standard Schedule?

The schedule is for adults who meet the prescribing criteria. People with a personal or family history of medullary thyroid carcinoma, MEN 2, pregnancy, or hypersensitivity to semaglutide should not use Wegovy. Adolescents, people with kidney or liver impairment and older adults may need special monitoring. See our article on who should not take GLP-1 medicines for the full list.

What to Expect Month by Month on the Wegovy Dosing Schedule

Many patients ask when they will see results. In the first month, the Wegovy dosing schedule uses the starter dose, so the main changes are smaller portion sizes and less food noise. By month two, appetite suppression is usually clearer and some people lose a few pounds. Months three and four, when doses reach 1 mg and 1.7 mg, are often when the scale moves more steadily. Weight loss then tends to continue for many months at the maintenance dose before slowing. This pattern is why prescribers judge progress over the full programme rather than after a few weeks. Expect fluctuations from water retention, hormones, travel and sleep, and focus on the overall trend.

Eating and Exercising During Dose Increases

Each step on the Wegovy dosing schedule can bring a few days of stronger side effects, typically the first week after an injection. Plan lighter meals on those days, keep protein high with foods such as eggs, yoghurt, fish and legumes, and sip fluids throughout the day. Gentle walking helps digestion, and resistance training two or three times a week protects muscle. Avoid large, greasy meals and carbonated drinks if you are nauseous, and consider keeping a food diary to identify triggers. If you drink alcohol, read our guide to GLP-1 medicines and alcohol, because reduced tolerance is common.

Illness, Travel and Surgery While on the Schedule

Life interrupts schedules. If you have vomiting or diarrhoea, you risk dehydration, so ask your prescriber whether to skip a dose. When you travel, keep pens cool and carry your prescription. If surgery or a procedure under sedation is planned, tell the care team that you use a GLP-1 medicine, because delayed stomach emptying can raise anaesthesia risks and your instructions on timing may change. If you pause for more than two consecutive doses, your prescriber may recommend restarting at a lower dose rather than resuming where you left off. Always follow the specific guidance for your product.

Key Takeaways on the Wegovy Dosing Schedule

The most important point is that the schedule is built for tolerance. You spend four weeks at each of the first four steps before reaching 2.4 mg, and nobody should rush it. Inject on the same day each week, record each dose and ask your prescriber before delaying or repeating a step. If side effects are heavy, eat smaller meals, drink fluids and report persistent vomiting or abdominal pain promptly. Remember that some people succeed at 1.7 mg, while others continue to 2.4 mg, so judge progress with your clinician, not by dose alone. Avoid buying pens from unverified sellers, because incorrect strengths undermine the titration plan. Our safe buying guide explains how to find a legitimate provider.
