How many clicks for my Ozempic dose?

Tap your pen color

💙 Blue Pen 0.25 – 0.5 mg Starting doses
🩶 Gray Pen 1 – 2 mg Mid-range doses
💚 Green Pen 2 – 4 mg Higher doses

For a prescribed dose of 1 mg on the Gray pen: you need 2 clicks. Each Gray pen click delivers 0.5 mg. Your pen holds 4 doses at this amount — roughly one month of weekly injections.

    Here's your rule of thumb

    The bigger the pen, the fewer clicks for the same dose.

    That's why the same dose needs different click counts on different pens:

    Blue pen (smallest) — 1 click = 0.25 mg

    Gray pen (mid) — 1 click = 0.5 mg

    Green pen (largest) — 1 click = 1 mg

    First time? Prime your pen first — the flow check uses a few clicks before your actual dose.

    Frequently Asked Questions

    The number of clicks depends on your pen strength and prescribed dose. Blue Pen (0.25-0.5mg): 1 click = 0.25mg, 2 clicks = 0.5mg. Gray Pen (1-2mg): 2 clicks = 1mg, 3 clicks = 1.5mg, 4 clicks = 2mg. Green Pen (2-4mg): 2 clicks = 2mg, 3 clicks = 3mg, 4 clicks = 4mg.

    If it has been 5 days or less since the missed dose, take it as soon as possible. If more than 5 days have passed, skip the missed dose and take your next dose on the regularly scheduled day. Never take two doses within 48 hours of each other.

    It depends on your dose and pen strength. Blue Pen at 0.25mg weekly lasts about 8 weeks, at 0.5mg about 4 weeks. Gray Pen at 1mg weekly lasts about 4 weeks, at 2mg about 2 weeks. Green Pen at 2mg weekly lasts about 4 weeks, at 4mg about 2 weeks.

    Common causes include using the wrong pen strength for your prescribed dose, incomplete clicks that don't fully deliver the intended dose, miscounting clicks, attempting non-standard doses that require partial clicks, and not maintaining the pen properly.

    No. Each Ozempic pen is designed for specific dose ranges. The Blue pen is for doses up to 0.5mg, the Gray pen for doses up to 2mg, and the Green pen for doses up to 4mg. Using the wrong pen can lead to significant under or overdosing.

    Methodology

    This calculator determines pen click counts based on the dose-per-click specifications described in the FDA-approved Ozempic (semaglutide) prescribing information by Novo Nordisk. The three pen strengths have fixed click-to-dose ratios: the Blue pen (0.25-0.5 mg) delivers 0.25 mg per click, the Gray pen (1-2 mg) delivers 0.5 mg per click, and the Green pen (2-4 mg) delivers 1 mg per click.

    The calculator divides the prescribed dose by the pen's dose-per-click value to determine click count, and flags non-integer results as potential dosing errors. Injection scheduling follows the standard once-weekly (every 7 days) administration interval, with missed-dose guidance based on the 5-day rule from the prescribing information.

    Ozempic (semaglutide) pens are color-coded by dose range. The Blue pen (0.25-0.5 mg) delivers 0.25 mg per click, so 0.25 mg = 1 click and 0.5 mg = 2 clicks. The Gray pen (1-2 mg) delivers 0.5 mg per click, so 1 mg = 2 clicks, 1.5 mg = 3 clicks, and 2 mg = 4 clicks. The Green pen (2-4 mg) delivers 1 mg per click, so 2 mg = 2 clicks, 3 mg = 3 clicks, and 4 mg = 4 clicks. Ozempic is injected once weekly, with at least 2 days between injections if the day needs to change.
