Dose Calculator for Fixed-Ratio Combination Pen Therapy

Because both drug components are delivered in a fixed ratio from a single pen, the maximum daily dose is capped to avoid exceeding the maximum recommended dose of either the insulin or the GLP-1 receptor agonist component. This means some patients who need higher basal insulin doses may not be suitable for this fixed-ratio formulation. Healthcare professionals should verify a patient's total daily dose needs fall within the pen's available range before prescribing.

The starting dose is generally based on the patient's current basal insulin dose, using a defined conversion approach to avoid an abrupt increase in total insulin exposure. A lower starting dose is often used when converting from higher insulin doses, given the added GLP-1 component. Healthcare professionals should follow the product-specific titration schedule and monitor fasting glucose closely after any dose change.

Titration is usually guided by fasting plasma glucose readings, with dose adjustments made at defined intervals until glycemic targets are reached, following the same general principle used for basal insulin titration. Patients should be counseled to report symptomatic hypoglycemia promptly, as this may require a downward dose adjustment. Regular follow-up during the titration phase helps optimize the dose more efficiently.
