Dose Calculator
Work out how many units to draw up for your prescribed dose, in either direction. Use it to check a number you already have — not to decide what your dose should be.
Both parts of the strength as printed on the label — the milligrams, and the millilitres they sit in. If the label just reads /mL with no number, that means 1. Concentrations change between orders, so read the vial in your hand.
Your most recent prescribed dose can be found via your latest provider consult message. If you have since titrated, verify your current dose on your Rx Summary. Enter it in milligrams or units and the calculator converts it to the other.
Run Your Numbers
Nothing you type here is sent to us or saved to your record.
Your label prints the strength as an amount of medication in an amount of liquid. Copy both numbers across exactly as you see them — don’t convert anything yourself.

Fill in your label and your doseYour most recent prescribed dose can be found via your latest provider consult message. If you have since titrated, verify your current dose on your Rx Summary.
Some compounded medications contain more than one ingredient, and the label gives a separate strength for each. Work through them one at a time, using the pair of numbers that belongs to the ingredient you are calculating.
Check It Twice, & Speak Up If Something Looks Off
This tool does arithmetic. It does not know your prescription, your titration schedule, or your history, and it cannot tell you whether a dose is right for you. Your individual prescription is what you follow.
That said, everyone in this chain is human — your provider, the pharmacy, and whoever printed the label. If the numbers do not line up, we would far rather you asked than assumed one side must be right. Raising it costs you a message. Not raising it can mean an injection at the wrong dose.
A single digit in the wrong place changes the answer by a lot. Re-read both parts of the strength off the vial, re-read your prescribed dose, and check them again before you draw anything up.
Do not inject, and do not adjust your dose to make the numbers agree. A mismatch is often just a number typed in wrong — but sometimes it is a real error on a label or a prescription, and that is exactly the kind of thing we want flagged.
- Set the syringe aside and leave the medication as it is.
- Message your provider through the patient portal with both parts of your vial’s strength, the dose you were prescribed, and the number you calculated.
- Wait for their answer before injecting. There is no harm in a dose being a little late while this is sorted out.
Wondering How Long Your Order Will Last?
The supply calculator totals up everything that arrived and divides it by your dose, so you can see how many weeks it covers.
This calculator is a convenience tool, not medical advice. Unit conversions assume a standard U-100 syringe, where 100 units is 1 mL. Your most recent consult message and your Rx Summary govern how much you take and when.
