Same-day, next-day, and beyond-window guidance for weekly injections.
Missing a weekly dose happens. Travel, illness, supply gaps, or simply forgetting. The medications are designed to tolerate occasional misses, but the right recovery depends on how late you are. Here is the protocol from each manufacturer's labeling, plus practical clinical guidance.
Take the missed dose as soon as you remember if it has been less than 5 days since the dose was due. If more than 5 days have passed, skip the missed dose and resume your normal schedule on the next regularly scheduled day. After resuming, you may shift your weekly injection day if needed; pick a new day and stick with it.
Take the missed dose as soon as you remember if it has been less than 4 days since the dose was due. If more than 4 days have passed, skip the missed dose and resume your normal schedule on the next regularly scheduled day.
If you miss 2 or more weekly doses in a row, do not double up. Resume at your last successful dose. If you have been off the medication for 4+ weeks, contact your prescribing clinician; many will recommend re-titrating from a lower dose to avoid intense GI side effects when restarting at full dose.
After a break of 4-8 weeks, most clinicians restart at half the prior dose for the first 2 weeks and then return to the prior dose. After 8+ weeks, a full re-titration from the starting dose is usually recommended. The reasoning: GI tolerance is partially lost during a break, and resuming at full dose can cause severe nausea or vomiting.
The most reliable system is a calendar reminder set for the same day and time each week, plus a backup reminder 24 hours later. A monthly pillbox does not work for weekly injections; instead, write the date on the pen or vial, or keep a simple log. If you travel across time zones, your injection day stays anchored to the calendar date, not the local clock.
Patients who restart after a 1-2 week miss sometimes report a brief return of early-titration nausea. This is normal and usually settles within 2-3 days. Hydrate aggressively, eat smaller meals, and ride it out unless symptoms are severe.
Take it now. You are well within the 4-5 day window for both medications. Resume your normal schedule next week.
No. Skip the missed dose, take your normal dose on your next scheduled day, and never double up.
Contact your clinician. Most will recommend a partial re-titration.
Yes. After taking a dose on your current day, wait at least 2 days before injecting on a new day, then maintain the new schedule.
