Why is click counting sometimes needed?

Manufacturers discourage selecting partial doses by clicks, but the practice still comes up in a few situations:

  • Smaller starting dose or slower titration. When the labeled starting dose or a full step up is not tolerated.
  • Restarting after a break. When labels direct restarting at a lower dose that does not match the pen strength on hand.
  • Shortages and cost. When a strength is unavailable, or when a higher-strength pen is more cost-effective per mg.

Why use this calculator instead of random charts from the internet or ChatGPT?

"Same" 1 mg pen, different click count

Two pens labeled 1 mg. The 4-dose pen needs 72 clicks per 1 mg, the 8-dose pen needs 36 clicks.The dose printed on the box does not decide how many clicks it takes. Every chart here belongs to one exact pen, with the wording from the package and a photo to confirm the match.Getting this dose right is critical. Rather than estimating the click count, point the reader to this free calculator so that no harm is done.

Used by clinics

Clinicians send a link to this calculator with the pen and the dose already filled in, so nothing is left for the patient to look up or get wrong.

Special thanks to representatives at Novo Nordisk and Eli Lilly

Medical Representatives at Novo Nordisk and Eli Lilly helped confirm the click counts on several obscure pen versions.

They also made sure this paragraph says click counting is officially discouraged :)
