What to do if humira pen misfires?

I’m not a doctor, but here are general safety steps if a Humira (adalimumab) Pen misfires:

- Do not reuse the misfired pen. Set it aside and use a new Humira Pen for your next dose if advised by your healthcare provider.
- Check whether any dose was delivered. If you’re unsure whether the injection occurred, treat it as not delivered.
- Use a new pen to complete your dose if it’s still within your dosing schedule. If you’re near your next scheduled dose or you’re unsure, contact your clinician before proceeding.
- Dispose of the misfired pen correctly in a sharps container or as advised by local guidelines.
- Keep notes about the incident: date/time, where you injected, lot number of the pen, and what happened.
- Watch for symptoms after any injection (fever, swelling, redness or pain at the injection site, signs of infection, allergic reactions like trouble breathing, severe rash). If you have any of these, seek medical care promptly.
- If you’re unsure what to do next (whether to adjust your schedule, or how to proceed), contact your rheumatologist, dermatologist, or the Humira patient support line (use the numbers in your product information/packaging or on Humira’s official site).
- Do not double-dose unless a healthcare professional tells you to.

If you’re experiencing a serious reaction or have trouble breathing, call emergency services right away.

If you’d like, tell me your country or the exact instructions you have from the Humira packaging, and I can tailor this to the official guidance. And always follow your clinician’s advice.
