Never run out. Mid-refill.

Most trackers only tell you when to inject — not how many doses are left in the pen sitting in your fridge. That gap is why people find out they're empty on shot day, not a week before. Here's the math, by medication.

THE MATH THAT MATTERS

Most GLP-1 pens last about 4 weeks. Log your fill date once, and the countdown to reorder runs on its own — no more finding out on a Sunday morning.

Basis: dosing and pen-capacity details per manufacturer prescribing information. See Ozempic pen dosing, Wegovy dosing, and Mounjaro prescribing information.

Q & A

How many doses are in an Ozempic pen?Q—01 +
The 1 mg and 2 mg pens each hold 4 doses — about 4 weeks. The 0.25 mg/0.5 mg starter pen holds 4 doses of 0.25 mg, then can still deliver 2 more doses of 0.5 mg — about 6 weeks total from one pen.
How many doses are in a Wegovy pen?Q—02 +
Single-dose pens, the most common format, hold 1 dose each and are sold in boxes of 4 — about 4 weeks per box. A multidose FlexTouch pen at the 2.4 mg strength holds 4 doses in one pen.
How many doses are in a Mounjaro or Zepbound pen?Q—03 +
Depends what your pharmacy dispenses. Single-dose pens hold 1 dose each. Multi-dose KwikPens hold 4 doses — about 4 weeks per pen.
When should I reorder my GLP-1 medication?Q—04 +
About a week before your current pen or box runs out, to leave room for pharmacy processing, insurance approval, or shipping delays.
Does GLP1ShotDay track this automatically?Q—05 +
Yes. Log your fill date once and the app counts down doses remaining based on your dosing schedule, then reminds you before you run out.

Your next refill,
not a surprise.
