Side-by-side

Dimension	Saxenda	Wegovy
Generic name	liraglutide	semaglutide
Manufacturer	Novo Nordisk	Novo Nordisk
FDA approved	2014	2021
Mechanism	Single GLP-1 receptor agonist. Same mechanism family as semaglutide/Wegovy but shorter half-life (~13 hours) requiring daily dosing instead of weekly.	Semaglutide mimics GLP-1, a gut hormone released after meals.
Dosing	Titrated weekly: 0.6mg → 1.2mg → 1.8mg → 2.4mg → 3.0mg maintenance, all once daily.	Titrated over 4-5 months: 0.25mg → 0.5mg → 1mg → 1.7mg → 2.4mg, increasing every 4 weeks.
Cost	List price ~$1,350/month. Cash-pay similar. Insurance coverage variable. Cheaper coupons through Novo Nordisk savings card programs.	List price ~$1,350/month without insurance.
Pivotal trial result	8.4% mean body-weight reduction at 56 weeks (3.0 mg dose)	14.9% mean body-weight reduction at 68 weeks

Efficacy in the trials

Saxenda

8.4% mean body-weight reduction at 56 weeks (3.0 mg dose)

SCALE Obesity & Prediabetes (NCT01272219) · vs 2.8% with placebo · n=3,731

Wegovy

14.9% mean body-weight reduction at 68 weeks

STEP 1 (NCT03548935) · vs 2.4% with placebo + lifestyle · n=1,961

Trial averages describe study populations, not individuals. Response varies with the dose tolerated, adherence, and personal physiology; the two drugs were not necessarily tested head-to-head in the same trial.

The details

Dosing & cadence

Saxenda: Titrated weekly: 0.6mg → 1.2mg → 1.8mg → 2.4mg → 3.0mg maintenance, all once daily.

Wegovy: Titrated over 4-5 months: 0.25mg → 0.5mg → 1mg → 1.7mg → 2.4mg, increasing every 4 weeks. Maintenance dose 2.4mg weekly. Slower titration is common to manage GI side effects.

Cost & access

Saxenda: List price ~$1,350/month. Cash-pay similar. Insurance coverage variable. Cheaper coupons through Novo Nordisk savings card programs.

Wegovy: List price ~$1,350/month without insurance. With Novo Nordisk's patient assistance program, eligible self-pay patients can access at $200-500/month. Insurance coverage is patchy and often requires prior authorization plus a documented weight-related comorbidity.

Side effects

Saxenda: GI side effects (nausea, vomiting, diarrhea) common during titration and somewhat more frequent than weekly GLP-1s because daily dosing means constant exposure. Same boxed warning for thyroid C-cell tumors as semaglutide.

Wegovy: Most common: nausea (especially first 4-8 weeks), constipation, diarrhea, fatigue, headache. Less common: gallbladder issues, pancreatitis (rare), kidney strain if dehydrated. Black-box warning: medullary thyroid cancer risk (theoretical, based on rodent studies). Discontinue and consult clinician for severe abdominal pain or persistent vomiting.

Which should you choose?

If maximizing average trial weight loss is the priority, Wegovy posted the higher pivotal-trial figure; Saxenda still produced clinically meaningful loss and some people tolerate it better. On cost and access, compare each drug's manufacturer direct-pay and insurance path — that often matters more month-to-month than the efficacy gap. Both carry class safety considerations (see each drug's boxed-warning and contraindications); a personal or family history of medullary thyroid carcinoma or MEN2 rules out the GLP-1 class. Bring this comparison to a prescriber, who will match the drug to your history and titrate the dose.

This is editorial framing, not a prescription. The right choice depends on your medical history, insurance, and a clinician's evaluation.

Frequently asked

Is Saxenda or Wegovy more effective?+

In their pivotal trials, Saxenda reported 8.4% mean body-weight reduction at 56 weeks (3.0 mg dose), while Wegovy reported 14.9% mean body-weight reduction at 68 weeks. Head-to-head results vary by patient profile, dose tolerated, and adherence — these trial numbers describe averages, not what every individual experiences.

How do Saxenda and Wegovy compare on cost?+

Saxenda: List price ~$1,350/month. Cash-pay similar. Insurance coverage variable. Cheaper coupons through Novo Nordisk savings card programs. Wegovy: List price ~$1,350/month without insurance. With Novo Nordisk's patient assistance program, eligible self-pay patients can access at $200-500/month. Insurance coverage is patchy and often requires prior authorization plus a documented weight-related comorbidity. Real out-of-pocket depends on insurance formulary tier, manufacturer savings programs, and whether a direct-pay channel is available.

Can I switch from Saxenda to Wegovy?+

Switching between brand-name treatments in the same drug class is common, but the conversion is not always 1:1. Discuss the switch with your prescriber — they'll usually re-titrate dosing rather than substitute equivalent strengths directly.

Are Saxenda and Wegovy the same drug?+

No. Saxenda (liraglutide) and Wegovy (semaglutide) are distinct medications from Novo Nordisk and Novo Nordisk respectively. They may share a drug class or mechanism but differ in active ingredient, dosing, and approved use.
