Zepbound pen
The long view

The branded product, prescribed properly.

Zepbound is dispensed as the manufacturer supplies it, on a prescription written after a clinician review. Whether it is appropriate for you is a decision for your clinician.

What is it

Zepbound is tirzepatide manufactured by Eli Lilly and approved by the FDA for chronic weight management in adults who meet defined criteria. It is dispensed by a licensed U.S. pharmacy on a prescription written after a clinician review.

How it works in the body

Acts on two receptors

Tirzepatide binds both the GIP and GLP-1 receptors, two incretin pathways involved in blood sugar and appetite signalling.

Slows gastric emptying

It slows the rate at which the stomach empties, which is part of how the GLP-1 pathway signals fullness.

Prescribed and reviewed

Dosing is set by your clinician, started low, and reviewed over time for as long as you are treated.

Switching

Yes. You can transfer from another provider and continue on the same or an equivalent dose. This is confirmed during your medical intake so the clinician can prescribe the right dose for you.
