How are estimated medication levels calculated?
Learn how Dosio estimates medication-level context from logged GLP-1 doses and why the result is educational rather than a measurement.
This app uses mathematical models to estimate medication concentration based on average data from peer-reviewed studies on how the body processes the active ingredients in GLP-1 medications.
Medication Half-Lives
The active ingredient in your medication determines how long it stays in your body. We use the following half-life values based on FDA prescribing information:
-
Ozempic®, Wegovy®
- Active Ingredient: Semaglutide
- Half-Life: ~7 Days (168 hours)
-
Mounjaro®, Zepbound®
- Active Ingredient: Tirzepatide
- Half-Life: ~5 Days (120 hours)
While this provides a general idea of typical drug behavior over time, it is not a measurement, and is not specific to individual health profiles. For any medication-related decisions, please consult with a healthcare professional.
What does the graph show?
When you log a dose, the estimate updates based on your medication and timing. Insights can show the current estimate, recent change, and the next scheduled dose together.
