About GLP-1 Dose Scheduler

About This Tool

GLP-1 Dose Scheduler is a free online calculator for once-weekly injection medicines — Ozempic, Wegovy, Mounjaro and Zepbound. It computes your next dose date, decides whether a missed dose should be taken now or skipped, builds week-by-week titration calendars, and tracks pen disposal dates. Every rule it applies comes from that product's FDA prescribing label, so the answers differ correctly between medicines.

Key Features

• Next dose date from your last injection
• Missed-dose decisions using each product's own FDA label window (5 days / 48 hours / 96 hours)
• Titration calendars with real dates for every dose level
• Pen expiry tracking (56 days for semaglutide pens, 30 days for Mounjaro KwikPen)
• Client-side processing — your dates never leave your browser

Important Limitations

This tool is a date calculator, not a medical service. It does not prescribe, adjust doses, or judge whether a medicine is right for you. After two or more consecutive missed weeks, the labels call for re-escalation decisions that only your prescriber can make. Always confirm treatment decisions with your healthcare provider.

Sources

Rules are taken from FDA prescribing information published on DailyMed (Ozempic rev 5/2026, Wegovy rev 6/2026, Mounjaro, Zepbound) and official Novo Nordisk / Lilly storage guidance. The rules-checked date is shown on the tool page.
