Zepbound injection sites: where to inject and how to rotate

What the Zepbound label says about where to inject, how to rotate and what changes with the vial, pen or KwikPen, with a planner to track it.

Quick answer

Zepbound (tirzepatide) is injected subcutaneously once weekly in the abdomen or thigh, or in the back of the upper arm if another person gives the injection [1]. The label says to rotate injection sites with each dose [1]. It can be taken at any time of day, with or without meals [1]. Your pen, vial or KwikPen has its own Instructions for Use, so ask your pharmacist or prescriber to show you the technique for your presentation.

Where you can inject Zepbound

  • Abdomen (stomach area) [1]
  • Thigh [1]
  • Back of the upper arm, only if another person injects it [1]

The label’s instruction is to rotate injection sites with each dose [1]. It does not say how far apart sites should be or give a fixed order, so follow the Instructions for Use that came with your product and your prescriber’s advice.

Pen, KwikPen or vial: get trained on yours

Zepbound comes as a single-dose pen, a single-patient-use KwikPen, and vials. The label says patients should receive training for the specific presentation they are given, and should read the Instructions for Use again if the presentation changes [1]. People using vials need a suitable syringe and a new syringe and needle for every injection [1].

The label also says the KwikPen is not recommended for self-administration by people who are visually impaired [1].

Frequently asked questions

Where is the best place to inject Zepbound?

The label allows the abdomen, the thigh, or the back of the upper arm if someone else injects it, and says to rotate sites with each dose. It does not rank them, so ask your prescriber if you have a preference.

Can I inject Zepbound in my arm myself?

The label says to inject the back of the upper arm only when another person gives the injection. Self-injection sites are the abdomen and thigh.

How often should I rotate Zepbound injection sites?

With each dose, according to the label. Because Zepbound is once weekly, that means a new spot every week.

Does Zepbound have to be injected at the same time every week?

It is once weekly at any time of day. The label allows changing the day if the gap between doses is at least 3 days (72 hours).

Is tirzepatide injected the same way as Mounjaro?

Yes. Zepbound and Mounjaro both contain tirzepatide, and both labels give the same injection sites and rotation instruction.
