Dosing in practice

Compounded semaglutide starts near 250 mcg once weekly and titrates monthly toward 1000 to 2400 mcg as tolerated. Brand pens are pre-dosed and need no math. Follow the pharmacy label.

Common questions

How much is 0.25 mg of semaglutide in units?
With a 5 mg vial and 2 ml of water the concentration is 2500 mcg per ml, so 250 mcg is 0.1 ml — 10 units.
Why does the dose increase over time?
Titration reduces nausea. Physicians raise the weekly dose stepwise about once a month.
Does this apply to Ozempic or Wegovy pens?
No. Pens deliver a fixed dose per click and never require reconstitution.
