Ozempic or Zepbound? An Honest Comparison (2026)

These two come up side by side all the time, and it’s easy to feel stuck choosing between them. We’ve laid out how Ozempic and Zepbound differ on the things that actually shape your day-to-day — results, cost, how you take them, and how they tend to feel — so you can head into your next appointment with a clear question instead of a guess.

The quick answer

In short: Ozempic (Semaglutide) helps people lose around 8–14% of their body weight at roughly $998/mo, while Zepbound (Tirzepatide) averages about 20–22% at roughly $1,060/mo. Neither is a clear winner for everyone — what tips the scale is your goals, what your insurance covers, and how your body takes to it.

Questions people ask us about these two

Often, yes — but it's a move to make with your doctor, not on your own, especially since these use different active ingredients (Semaglutide vs Tirzepatide). Your prescriber will set a sensible starting dose and step you up gradually so your body has time to adjust.

In studies, Ozempic averages about 8–14% of body weight and Zepbound averages about 20–22%. Those are averages, though — your own results hinge on your dose, your habits around food and movement, and your metabolism, so treat the numbers as a guide rather than a promise.

At full list price, Ozempic runs roughly $998/mo and Zepbound about $1,060/mo. But list price is rarely what people actually pay — once insurance, manufacturer savings, or a cash-pay program enter the picture, your real cost can look very different.

They're cut from the same cloth, so both can bring on stomach-related effects like nausea, diarrhea, or constipation, usually most noticeable early on as your dose climbs. How strong those effects feel can differ from person to person, which is one more reason to talk through your history with your doctor.
