A GLP-1 dose schedule calculator turns a first-dose date into a dated titration calendar for Wegovy, Zepbound, Ozempic, Mounjaro, Saxenda, or Rybelsus. Use it to see the standard dose escalation pathway, the next planned increase, the weeks to a selected target dose, and how clinician-directed holds can change the calendar while keeping prescribing-information limits visible.
How the GLP-1 titration calendar works
The calculator starts with the medication you select and the first-dose date you enter. It then walks through the labelled dose steps in order, assigning a start date, end date, dose amount, and duration to each phase. Weekly medicines are shown as once-weekly injection schedules; daily medicines are shown as daily oral or daily injection schedules.
The standard cadence is deliberately conservative: most weekly GLP-1 and GIP/GLP-1 labels hold each dose for at least four weeks before increasing. That slower dose escalation is meant to improve tolerability, especially for nausea, vomiting, constipation, diarrhea, reflux, dehydration, and other gastrointestinal side effects that can appear during dose increases.
The page also lets you model a clinician-directed hold at each non-maintenance step. A hold does not mean the label has changed. It shows how the calendar shifts if a prescriber chooses to keep you on a dose longer because of side effects, treatment response, medication access, or a lower maintenance target.
Phase start date = prior phase start date + prior phase duration
Each new dose phase begins after the previous labelled or clinician-held phase ends.
Weeks to target = sum of all non-maintenance phase durations
The calculator totals the weeks before the selected target or maintenance dose begins.
Wegovy, Ozempic, Zepbound, and Mounjaro schedules
The Wegovy titration schedule starts at 0.25 mg once weekly and usually increases every four weeks through 0.5 mg, 1 mg, and 1.7 mg before the 2.4 mg maintenance dose. For a user who starts on a Monday, the calculator shows the matching Monday injection cadence and the date each new dose is expected to begin.
The Ozempic dosing schedule also starts at 0.25 mg once weekly, but its diabetes-label pathway has a different target-dose logic than Wegovy. The calculator therefore keeps Ozempic as its own medication choice instead of treating every semaglutide product as interchangeable.
The Zepbound dosing schedule and Mounjaro dosing schedule use tirzepatide. They start at 2.5 mg once weekly, move to 5 mg after at least four weeks, and can increase in 2.5 mg steps through 7.5 mg, 10 mg, 12.5 mg, and 15 mg depending on indication, response, and tolerability. The calculator can stop the displayed plan at a clinician-selected target such as 10 mg while still showing the label maximum for context.
Saxenda and Rybelsus need separate handling
Saxenda is a daily liraglutide injection, so its calendar does not behave like a once-weekly pen schedule. The calculator uses daily titration phases and avoids showing a weekly injection day when the medicine is not dosed weekly.
Rybelsus is oral semaglutide for type 2 diabetes, not a weekly injection. Its schedule is also kept separate because oral dosing instructions, timing with food or other medicines, and target-dose decisions differ from injectable semaglutide products.
Worked example: a Wegovy start date with a tolerability hold
Suppose Wegovy is started on 8 January 2024. A standard labelled calendar reaches the 2.4 mg phase after 16 weeks of escalation: four weeks at 0.25 mg, four weeks at 0.5 mg, four weeks at 1 mg, and four weeks at 1.7 mg before the selected target begins.
If the prescriber decides to hold each non-maintenance step for four extra weeks, the same first-dose date produces a much slower Wegovy dose escalation schedule. The target dose begins later, the next escalation date shifts out, and the result summary makes that pacing visible instead of leaving the user to recalculate a calendar manually.
How to interpret a lower target dose
A lower target dose is not the same thing as quitting titration early on your own. For some medicines and indications, lower maintenance doses are explicitly part of the label; for others, a lower dose may reflect tolerability, response, or a clinician-specific plan. The calculator labels the selected target separately from the standard maximum so the distinction is clear.
This matters most for tirzepatide searches such as “Zepbound titration schedule” or “Mounjaro dose schedule,” because users often want to know whether they must reach 15 mg. The practical answer is that the prescriber should choose the maintenance dose based on indication, response, side effects, and label context, not only the existence of a higher strength.
Missed doses, side effects, and restart questions
A dated schedule is not a missed-dose calculator. Official labels use medication-specific missed-dose instructions, and the answer can depend on how many days have passed, how soon the next scheduled dose is due, and whether multiple doses were missed. The result panel therefore surfaces a medication-specific reminder rather than telling users to double up or self-restart.
Clinician review is especially important after repeated vomiting, dehydration, severe abdominal pain, persistent constipation, gallbladder symptoms, low blood sugar symptoms in people using insulin or sulfonylureas, pregnancy planning, or any situation where the next dose feels unsafe. A calendar can organize questions, but it cannot decide whether the next escalation is clinically appropriate.
What this calculator does not cover
This planner does not prescribe medication, diagnose eligibility, manage diabetes, select between brands, calculate compounded vial units, or override pharmacy instructions. It also does not model every country-specific product strength, every formulation update, insurance constraints, medication shortages, or individualized restart protocols.
Use the result as a structured calendar to discuss with a licensed clinician or pharmacist. Before changing a GLP-1 dose, confirm the medication name, strength, route, indication, start date, side-effect history, missed-dose history, and current prescribing information.
Frequently asked questions
Can I speed up my GLP-1 titration schedule?
Do not increase faster than your prescription or clinician's instructions. Wegovy, Zepbound, Ozempic, Mounjaro, Saxenda, and Rybelsus all use gradual titration because faster dose escalation can worsen nausea, vomiting, dehydration, constipation, and other side effects. If the current dose feels ineffective, ask your prescriber rather than changing the calendar yourself.
What day of the week should I inject Wegovy or Ozempic?
For once-weekly injections, your injection day is usually the day of the week you choose and then repeat consistently. The calculator shows the weekly injection day based on the first-dose date you enter. If you need to change injection day, follow the current medication guide or ask your prescriber because the allowed spacing differs by product.
How long does it take to reach the Wegovy maintenance dose?
With the standard Wegovy dose escalation schedule, the 2.4 mg phase begins after 16 weeks of lower doses: 0.25 mg, 0.5 mg, 1 mg, and 1.7 mg, each held for four weeks. Clinician-directed holds can make the calendar longer, and some patients may stay at a lower dose if tolerability or the prescribing plan requires it.
How long does Zepbound titration take?
A standard Zepbound schedule starts at 2.5 mg for four weeks, then 5 mg for at least four weeks, with possible 2.5 mg increases after at least four weeks on the current dose. Reaching 15 mg follows a longer six-step calendar than Wegovy, but 5 mg, 10 mg, or 15 mg may be relevant maintenance doses depending on indication and clinician judgment.
Can I stay on a lower GLP-1 dose if it works for me?
Sometimes, but that decision belongs with your prescriber. A lower maintenance or selected target dose may be reasonable for tolerability, response, or label-specific reasons. The calculator can show a lower selected target dose so you can see the calendar impact, but it does not decide whether that dose is clinically appropriate.
What should I do if I miss a Wegovy, Ozempic, Zepbound, or Mounjaro dose?
Use the missed-dose instructions for the exact product you take, because the timing windows are medication-specific. Do not double doses to catch up. If you missed multiple doses, had severe side effects, or are unsure whether to restart at the same dose, contact your prescriber or pharmacist before taking the next dose.
Does this calculator work for compounded semaglutide or compounded tirzepatide?
No. This page models labelled brand schedules and dose strengths, not compounded concentration, vial units, split dosing, or non-standard microdosing. Compounded products can vary by concentration and instructions, so a dose calendar or unit conversion should be confirmed directly with the prescribing clinician and dispensing pharmacy.
Why does the calculator show Ozempic and Wegovy separately if both are semaglutide?
They share the same active ingredient, but the labelled use, target dose, product instructions, and clinical pathway differ. A Wegovy dose schedule calculator should not silently substitute Ozempic dosing, and an Ozempic dosing schedule should not imply a Wegovy weight-management target.
When should I ask for review before increasing my GLP-1 dose?
Ask for review before escalating if side effects are not settling, if you have vomiting or dehydration, if constipation is severe, if abdominal pain is significant, if blood sugar is running low, if pregnancy is possible, or if the medication label or pharmacy instructions do not match the calendar you expected.
