GLP-1 Dose Schedule Calculator
Every GLP-1 label describes the same shape of schedule: start low, step up no faster than every 4 weeks, and settle at a maintenance dose. This calculator takes the published schedule for your medication and turns it into calendar dates from your start date, so you can see what the standard pattern looks like on a real calendar.
How this schedule works
The schedules in this tool are the escalation patterns printed in the FDA prescribing information for each medication. Everyone starts on a low dose that is meant for getting used to the medicine, not for full effect: 0.25 mg for Ozempic and Wegovy, 2.5 mg for Mounjaro and Zepbound. Each stage then lasts at least 4 weeks before any increase, and each increase date in the table is simply 28 days after the previous stage began.
The patterns differ after the first step. Wegovy follows fixed 4 week steps up to its 2.4 mg maintenance dose. Zepbound steps up in 2.5 mg stages, with 5 mg, 10 mg and 15 mg as the recommended maintenance doses. Ozempic moves to 0.5 mg and then only rises if the prescriber decides more effect is needed, up to a 2 mg maximum. Mounjaro follows the same idea, with optional 2.5 mg increases up to a 15 mg maximum. Rows marked optional only happen if your prescriber increases your dose, and many people stay on a lower dose long term.
What this tool cannot do is set your schedule. Side effects, other conditions, other medicines and how you respond all change the pace, and restarting after a break follows its own rules. If your actual dates drift from this table, that is normal and common, not a problem to fix on your own.

Frequently asked questions
Does this schedule tell me when to increase my dose?
No. It lays out the published label escalation pattern with calendar dates, which is the standard pattern the labels describe. Your prescriber may keep you on a dose for longer, pause increases because of side effects, or change the plan entirely. Never increase, decrease or restart a dose based on this tool.
Why does each stage last at least 4 weeks?
The labels build in at least 4 weeks at each step so your body can adjust and side effects can settle before any increase. Rushing the steps tends to make nausea and other side effects worse, which is why prescribers often move more slowly than the label pattern, not faster.
What if I miss a week or restart after a break?
Missed dose rules and restarting after a break depend on the medication and on how long the gap was, and restarting at a full dose after a long break can cause strong side effects. Read the missed dose section in the dosage chart for your medication and ask your prescriber or pharmacist before restarting.
