What if I missed my Ozempic shot?

How to count the five days

Count from the day the shot was due. If your day is Sunday, the window runs to Friday: a shot remembered on Wednesday goes in on Wednesday, and next week's shot is back on Sunday. Remembered on Saturday, more than 5 days have passed: that week's shot is skipped, and the next one is on Sunday as usual. The label never asks for two shots to make up for one.

Changing your shot day

The same section allows a new day, with one condition:

From the label

The day of weekly administration can be changed if necessary as long as the time between two doses is at least 2 days (>48 hours).

So a missed week is not the only moment to move the shot. A new day can be chosen at any time, as long as two doses stay at least 2 days apart.

Why a missed week is not a cliff

Ozempic stays in the body a long time. The pharmacokinetics section (§12.3) puts it this way:

From the label

With an elimination half-life of approximately 1 week, semaglutide will be present in the circulation for about 5 weeks after the last dose.

One late shot does not empty that. The label does not, however, describe how blood sugar behaves after a skipped week, and it gives no restart rule after several missed weeks: both are for the prescriber, who reads your glucose numbers.

Each weekly shot has its own window in its own label, so the rule here is the one for Ozempic only. Oolite's shot log keeps the day of each injection, so a late or skipped week is a dated line in the report for your prescriber.

Questions people ask

I remembered on day 3. Do I still take it?

Yes. Day 3 is inside the 5 days the label gives, so the shot goes in as soon as possible, and you then return to your usual day the following week.

It has been 6 days. Can I take it and shift my week?

The label says to skip the missed dose once more than 5 days have passed, and to take the next one on the regularly scheduled day. Moving the shot day is a separate question, covered just below.

Can I change my Ozempic day for good?

Yes, the label allows it, as long as there are at least 2 days (more than 48 hours) between two doses. The Medication Guide puts it as your last dose having been given 2 or more days before.

I missed several weeks. Do I restart at my old dose?

The Ozempic label gives no rule for that case. It is a question for the prescriber, who knows the dose you were on and how the first weeks went. The Medication Guide asks you to use Ozempic exactly as your healthcare provider tells you to.
