Note: The 0.25 mg and 0.5 mg pens are low-dose pens; the 1.0 mg, 1.7 mg, and 2.4 mg pens are high-dose pens with more total clicks. Scenario: You have a 1.0 mg pen (74 clicks for full dose). Your doctor approves a 0.5 mg dose.

Find clicks per 1 mg for this pen. 74 clicks ÷ 1.0 mg = 74 clicks/mg.

Multiply by desired dose. 74 clicks/mg × 0.5 mg = 37 clicks .
