How Semaglutide Dosing for Weight Loss Generally Works
Semaglutide is a GLP-1 receptor agonist — a class of prescription-only injectable medicines that act on appetite-regulating pathways in the brain and slow gastric emptying. For weight management, Wegovy (semaglutide) is commonly prescribed as a once-weekly subcutaneous injection. According to the electronic Medicines Compendium, Wegovy prescribing information describes a structured titration schedule starting at a low dose, with increases at set intervals to allow the body to adjust, before reaching a maintenance dose — all under prescriber direction.
Why titration matters
Starting low and increasing gradually is standard practice with semaglutide. This approach is designed to minimise gastrointestinal side effects — such as nausea, which is commonly reported — while the body adapts. Many people find that side effects are most noticeable in the first days after a dose increase, and that they often ease as the body adjusts. Your prescriber will decide the pace of any increase; it is not something to self-manage.
Injectable versus oral semaglutide
It is worth noting that oral semaglutide formulations exist, though their licensed indications and dose ranges differ from the injectable Wegovy pen. If you have been prescribed oral semaglutide, your prescriber will have explained the specific regimen; the general principle of a low starting dose and prescriber-led adjustment still applies. Never change the form or dose of your medicine without speaking to your prescriber first.
How this compares to other GLP-1 medicines
People sometimes ask how semaglutide dosing compares to tirzepatide (Mounjaro) or liraglutide (Saxenda). These are distinct medicines with different active substances, mechanisms, and dose ranges, and direct comparisons are not meaningful for any individual — the right medicine and dose is always a prescriber's decision based on your personal health picture. If you are curious about how Mounjaro dosing for weight loss works, that is covered separately.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.

Tracking Your Semaglutide Doses with GLP Trackr
Keeping an accurate record of every dose you take is one of the most practical things you can do on a weekly injection schedule — and it is where GLP Trackr is built to help.
Dose logging and reminders
The app's dose logging feature lets you record each injection: the date, time, and dose strength, so you always have a clear history of where you are in your treatment. Because Wegovy is taken once a week, it can be surprisingly easy to lose track — especially during titration when the dose changes. GLP Trackr's dose reminders mean you are gently prompted each week, reducing the chance of a missed injection. If you do miss a dose, log it in the app and discuss next steps with your prescriber; the decision on how to proceed always belongs with them, not with an app.
Building a record to bring to appointments
The doctor report feature lets you bring a clear, organised summary of your dose history, side effects, and progress to your prescriber appointments — making those conversations more productive. This is particularly useful during titration, when your prescriber needs to know how you have been responding to the current dose before deciding whether to adjust it.
If you are also interested in how finding the right Mounjaro dose works, or understanding Mounjaro maintenance dosing, those pages cover the tirzepatide equivalents in more detail. For a broader overview of GLP-1 dosing, you may also find our Mounjaro dosing guide a useful reference point.
Always follow the guidance of your prescriber or doctor — they know your full medical history and are the only person who should advise on your dose. If you experience side effects that feel severe or persistent, contact your healthcare professional promptly rather than adjusting your dose independently.

Frequently asked questions.
Semaglutide for weight loss is typically started at a low dose and increased gradually over several months. The exact starting point and titration schedule are determined by your prescriber based on your individual circumstances — dose decisions are never self-managed.
Your prescriber sets and adjusts your semaglutide dose based on how you are responding to the medicine, any side effects you experience, and your overall health. No one should change their dose without speaking to their prescriber first.
If you miss a dose, contact your prescriber or consult the patient information leaflet that came with your medicine for guidance. You can log a missed dose in GLP Trackr to keep an accurate record and discuss it at your next appointment. Never double up without clinical advice.
Oral and injectable semaglutide have different dose ranges and licensed indications. Your prescriber will explain the regimen specific to your prescription. The general principle — a low starting dose adjusted under clinical supervision — applies to both forms.
GLP Trackr lets you log each weekly injection — including the date, time, and dose strength — and sends reminders so you never miss a dose. You can also generate a dose history summary to share with your prescriber at appointments.
