Not everyone ends up at the top of the dose ladder, and plenty of people were never meant to. If you're settling below the maximum labeled dose, that is often exactly the right outcome.
Is the highest dose the "full" treatment?
It's easy to assume that reaching the maximum labeled dose is the complete, most successful version of treatment, and that stopping lower means falling short. Dosing decisions don't work that way (our guide on what maintenance dose actually means has the fuller picture). For many people, a lower maintenance dose is the clinically right one.
The ceiling itself can move, too. As of September 2026 the Wegovy label goes up to 7.2 mg for some adults, but 1.7 mg and 2.4 mg remain its standard maintenance doses.
Good reasons to stay below the maximum
The first is simple: you're already getting the effect you and your prescriber are aiming for. If your blood sugar is well controlled, or your weight is coming down at a steady pace you can sustain, there's often no clinical reason to go higher just because a higher dose exists.
Side effects are another. More dose generally means more effect and more side effects, and for some people that trade stops being worth it, so settling at the earlier, better-tolerated dose makes sense. It also helps to know that side effects aren't what makes the medication work. An analysis of four tirzepatide trials found that nausea, vomiting, diarrhea and indigestion accounted for at most about 3% of the weight lost, and people with no nausea lost a similar amount to those who had it (Rubino et al., Diabetes, Obesity and Metabolism, 2025, DOI (external link)). A dose you tolerate can still be a dose that works.
Your goal matters as well. Someone focused on body recomposition, or mainly managing blood sugar, may have a lower target dose than someone aiming for maximum weight loss.
Cost can play a part. Some self-pay prices rise with the dose. Lilly announced its current self-pay prices for Zepbound single-dose vials in December 2025, and as of September 2026 LillyDirect still lists them: $299 a month for 2.5 mg, $399 for 5 mg and $449 for 7.5 mg and above (the $449 price requires refilling within 45 days). Prices and coverage change, so check what applies to you. Either way, cost is a fair thing to raise in a shared decision with your prescriber.
What the trials show about lower doses
There's now direct trial evidence that a reduced dose can hold weight off for many people. In the SURMOUNT-MAINTAIN trial, people who had lost weight over 60 weeks on their highest tolerated dose of tirzepatide were randomly assigned to keep going, drop to 5 mg, or switch to placebo. At week 112, those on 5 mg were still 16.6% below their original weight. That was less than those who stayed on the maximum tolerated dose (−21.9%) but far more than those on placebo (−9.9%). About 1 in 4 people on 5 mg regained at least half of what they'd lost, compared with about 1 in 12 on the full dose (Horn et al., The Lancet, 2026, DOI (external link)).
Be clear about what that trial tested. Everyone first reached a high dose and then stepped down. Settling at a lower dose on the way up and never going higher is a different situation, and no trial has tested it directly. The trial was also funded by the drug's manufacturer, ran only in the US, and enrolled people with an average BMI of about 40, so it may not describe everyone. If you've reached your goal and are weighing a reduced dose against stopping, our guide on tapering versus maintenance walks through that choice.
For staying at a lower dose from the start, the closest evidence is long-term. In three-year results from SURMOUNT-1, people assigned to tirzepatide 5 mg were still 12.3% below their starting weight at 176 weeks, compared with 18.7% on 10 mg and 19.7% on 15 mg (Jastreboff et al., The New England Journal of Medicine, 2025, DOI (external link)). The lower dose gave a smaller result, but one that lasted.
Make the decision with your prescriber
If you're thinking about staying at a lower dose, because of side effects, because you're happy with your results, or for another reason, say so directly. Don't just quietly stop moving up through titration on your own. Your prescriber can help you judge whether your current dose is meeting your goals with side effects you can live with, which matters more than whether it's the highest number on the label.
