- How does Zepbound compare with Wegovy?
- Both are once-weekly weight-loss injections. Zepbound's tirzepatide hits GIP and GLP-1 receptors; Wegovy's semaglutide hits GLP-1 only. In Lilly's head-to-head trial, tirzepatide produced greater average weight loss.
- What is the starting dose?
- Treatment starts at 2.5 mg once weekly for four weeks, then steps up under your prescriber's plan. The 2.5 mg KwikPen holds four doses.
- Do the pens come with needles?
- The KwikPen and single-dose vials do not include needles. Vial users need to buy pen or syringe needles separately; check what your prescription format requires.
- Can I switch between the pen and the vials?
- The formats are dosed differently, so a pen strength and a vial strength are not interchangeable. Ask your prescriber which format and dose your prescription specifies.
- What happens if I stop taking it?
- Appetite suppression fades after the last dose, and many people regain much of the lost weight unless diet and activity habits change. Plan a maintenance strategy with your clinician.
- Who should not use it?
- It is not for people with a personal or family history of medullary thyroid carcinoma or MEN2, and it is not recommended during pregnancy. Tell your prescriber about pancreatitis or gallbladder problems.
