This free GLP-1 dose schedule calculator builds your personal titration calendar for Wegovy, Ozempic, Zepbound, Mounjaro, Rybelsus, Saxenda, or the Wegovy pill. Enter your start date and see the earliest date you could reach each dose step under the official FDA-label escalation schedule.
How the GLP-1 Dose Schedule Works
Every GLP-1 medication starts low and steps up gradually — the starter doses exist to let your digestive system adapt, not to drive results. The schedules in this GLP-1 dose schedule calculator come from the FDA prescribing information: 4-week steps for Wegovy, Zepbound, Mounjaro, and Ozempic, 30-day steps for Rybelsus, and weekly steps for Saxenda. Escalation is always conditional on tolerating the current dose; slower is common and completely normal.
Two practical notes: nausea and other side effects cluster around dose increases (our nausea guide covers what helps), and if you miss doses during titration your schedule shifts — see our missed dose calculator for what the labels say. Compounded semaglutide and tirzepatide typically mirror the Wegovy and Zepbound schedules, but follow your telehealth provider’s plan.
GLP-1 Dose Schedule FAQ
How long does it take to reach the full dose?
At the fastest label pace: about 16 weeks to reach Wegovy 2.4 mg, 20 weeks to Zepbound or Mounjaro 15 mg (if you go that high), and 4 weeks to Saxenda 3 mg. Many people take longer, and many maintain at a middle dose.
Do I have to increase to the maximum dose?
No. Steps above the first maintenance level are taken only if needed for response and tolerated. Plenty of people get strong results at 5–10 mg tirzepatide or 1.7 mg semaglutide — the right dose is the one you and your prescriber land on.
What if side effects hit after a dose increase?
That’s the most common pattern. Prescribers often hold the current dose an extra 4 weeks, or step back down briefly. Log symptoms alongside each dose so your prescriber can see exactly how each step treated you.
