Quick Answer

I missed a dose—what should I do?

In general: don’t double-dose. The best next step depends on how many days late you are.

How late are you?

Use these simple categories to decide what to do next.

1–2 days late

Often you can take it and continue your weekly schedule from there.

3–4 days late

May still be okay, but timing matters—consider checking with FMC.

5+ days late

Reach out to FMC for the safest plan to restart without side effects.

What if I missed multiple weeks?

Contact FMC. Restarting may require a clinician-guided plan to improve tolerability and safety.

What not to do

Avoid actions that increase side effects.

  • Do not “catch up” with a double dose
  • Do not change your dose on your own
  • Do not inject early to “make up time” without guidance
