Converts a dose in mg into millilitres and 100-unit insulin syringe units, using the real concentration of the specific Ozempic or Wegovy pen you select. Informational only — not medical advice.
ℹ️This tool is for informational purposes only and does not provide medical advice. Pen concentrations are taken from official prescribing information; always follow your prescriber's and pharmacist's actual instructions, and the packaging of the specific product you were dispensed. Wegovy pens are single-dose and pre-set — they are not designed to be drawn from, and Ozempic's dial already delivers its listed doses without a syringe. Never change your dose or injection method without speaking to a registered healthcare professional.
FAQ
Dosage Calculator — FAQ
Calculations use the exact concentration published in each product's official prescribing information, but they are not medical dosing instructions.
The calculator uses standard 100-unit insulin syringes (1 mL = 100 units), the same convention used in most South African diabetes care.
Currently, the tool supports one calculation at a time. Use the Household Planner if you need to total several separate prescriptions.
Ozempic and Wegovy are sold in several pen strengths, each with a different concentration — the same mg dose needs a different mL volume depending on which pen it comes from.
Rybelsus is an oral tablet, not an injection — there's no volume or syringe conversion to calculate.
