The daily-injection elder: −8% in SCALE, beaten −15.8 to −6.4 by weekly semaglutide in STEP 8 — yet still standing on three legs: the earliest adolescent approval, a short half-life some situations prefer, and the class’s first generics.
Deeper data: the trial index holds every figure above with sources; the fair fight, the adolescent niche.
Liraglutide is the class’s previous generation: a daily injection, roughly half the average weight loss of semaglutide 2.4 mg — and, since generics arrived, potentially the cheapest legitimate GLP-1 on the market.
Evidence and dosing
As Saxenda (3 mg daily, titrated from 0.6 mg) it averaged about 8% weight loss in the SCALE program; as Victoza (up to 1.8 mg) it is a diabetes drug with cardiovascular outcome benefit (LEADER). Daily injection is the tax; a shorter half-life is the mechanism.
Why it still matters in 2026
Generic liraglutide entered the U.S. market beginning in 2024, and generics change the affordability conversation in a way no coupon does. For a patient without coverage, for whom even direct self-pay brand channels or verified compounded flat rates are out of reach, a generic daily GLP-1 with real — if smaller — trial-proven efficacy can be the honest budget answer. Current generic pricing varies by pharmacy; verify locally or via discount-card aggregators. It also remains a fallback when weekly agents aren’t tolerated.
Safety essentials
Same class boxed warning and GI profile, compressed into daily dosing. The trade-offs against weekly agents — efficacy, adherence, side-effect rhythm — are covered across our journal files.
Dosing reality and side-effect rhythm
Saxenda titrates 0.6 → 1.2 → 1.8 → 2.4 → 3.0 mg over roughly five weeks, and the daily schedule changes how side effects feel: instead of the weekly wave many people get with long-acting agents, nausea and appetite effects arrive in smaller daily pulses. Some stomachs prefer that; some don’t. Missed-day recovery is simpler than with weekly agents, but there are seven chances a week to miss.
Where to actually get it cheap
The generic is the point. Brand Saxenda pricing never justified itself once weekly agents arrived; generic liraglutide through ordinary retail pharmacies — priced via discount-card aggregators and pharmacy shopping — is where the affordability story lives, and it needs no telehealth subscription at all if your own clinician will prescribe it. Verify local prices; they vary widely by pharmacy and fill size. For the budget decision tree this slots into, see the affordable-routes map.
Practical dosing notes
Daily dosing forgives differently: a missed day is simply resumed the next (no doubling), but the habit burden is real — pairing the injection with a fixed daily anchor like brushing teeth measurably helps adherence. Pens require standard cold-chain care before first use; the medication guide covers in-use storage windows.
