Tirzepatide may be supplied in different concentrations depending on the pharmacy and prescription you receive. Because of this, the number of syringe units required for the same dose may vary between patients and shipments.
Always follow the prescription label included with your medication shipment.
This guide explains how to understand your syringe and safely prepare your prescribed dose.
Understanding Your Syringe
Most patients receive a 100-unit insulin syringe.
Basic syringe conversion:
1 mL = 100 units
1 large line = 10 units
1 small line = 2 units
Your prescription label will tell you:
Your prescribed dose
Your medication concentration
The exact number of units to draw into the syringe
Important Safety Note: Tirzepatide concentrations may vary significantly between pharmacies and prescriptions. Always verify the prescription label before injecting. The label contains the exact number of units you should take. Never rely on old dosing instructions, online charts, or another patient’s prescription.
Why Your Units May Change
Tirzepatide prescriptions can be prepared in different concentrations. Because of this:
The same mg dose may require different syringe units
Future shipments may look slightly different
Your units may change if your pharmacy or concentration changes
This does not necessarily mean your dose changed.
Always use the instructions printed on your current prescription label.
Understanding Units, mL, and mg
Your prescribed dose is usually written in milligrams (mg), while your syringe measures liquid volume in units or milliliters (mL).
Because tirzepatide concentrations vary, the number of syringe units needed for the same mg dose can differ between prescriptions.
If you are unsure how to interpret your syringe measurement, contact support before injecting.
