Elimination half-life "approximately 13 hours" after subcutaneous administration, maximum concentrations "achieved at 11 hours post dosing", absolute bioavailability "approximately 55%". Confirms the 13-hour half-life used here. FORMULATION NOTE: this label describes a 6 mg/mL solution in a prefilled pen, which is NOT reconstituted. The half-life is a property of the molecule and applies either way, but the vial sizes shown here reflect the lyophilised compounded/research presentation this calculator is for. If you have a pen, the reconstitution steps do not apply to you.
