Where 0.25 mg fits in the schedule
The starting dose on the Wegovy and Ozempic schedules, usually taken for the first 4 weeks. It is meant to help your body adjust, not as a long-term dose. Your prescriber sets your actual schedule — follow their instructions.
The formula
units = (dose mg ÷ concentration mg/mL) × 100
Example at 2.5 mg/mL: 0.25 ÷ 2.5 × 100 = 10 units.
Brand-name Wegovy and Ozempic pens deliver fixed doses in mg — you don't count units with a pen. These numbers apply to vials drawn up with a syringe. Always follow your prescriber and your pharmacy label.
