How Saxenda works
Saxenda contains liraglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. It mimics gut hormones released after eating, producing three core effects (see our deeper explainer on how GLP-1s work):
- Slowed gastric emptying — food stays in your stomach longer, increasing fullness.
- Reduced appetite signaling — the drug acts on the hypothalamus to suppress hunger and food noise.
- Glucose-dependent insulin release — pancreatic beta cells release insulin only when blood sugar is elevated, lowering A1c without typical hypoglycemia.
Who Saxenda is for
Adolescents 12+ with obesity, or adults intolerant to weekly GLP-1s.
FDA-approved indications:
- Chronic weight management (adults and children 12+)
Who should avoid it
- Personal or family history of medullary thyroid carcinoma or MEN 2 syndrome
- History of pancreatitis
- Severe gastroparesis or inflammatory bowel disease
- Pregnancy, planning pregnancy within 2 months, or breastfeeding
- Active gallbladder disease (relative contraindication)
See our full safety guide for context on each contraindication.
How to take Saxenda
Starting dose: 0.6 mg daily
Maximum dose: 3 mg daily
- Inject subcutaneously in the abdomen, thigh, or upper arm.
- Once per day, around the same time, with or without food.
- Rotate injection sites to prevent skin irritation.
- Doses are titrated up monthly to minimize nausea — do not skip ahead.
Side effects
Common (≥5% of users):
- Nausea
- Hypoglycemia
- Diarrhea
- Constipation
- Vomiting
Serious warnings:
- Boxed warning: thyroid C-cell tumors
- Pancreatitis
- Gallbladder disease
- Suicidal ideation reports
Most GI side effects appear during dose escalation and ease within 2–4 weeks. Eating smaller meals, avoiding greasy foods, and staying hydrated helps — our side-effect management guide covers practical tactics in detail. Persistent severe abdominal pain warrants immediate medical evaluation to rule out pancreatitis or gallbladder disease.
Where to get Saxenda
- Primary care or endocrinology: The most reliable route — your clinician handles prior authorization and monitoring.
- Telehealth platforms: Services like Ro, WW Clinic (Sequence), Form Health, and Hims/Hers prescribe FDA-approved GLP-1s after a video evaluation. Verify they prescribe the brand name, not just compounded versions.
- Direct-to-consumer: NovoCare offers savings cards and patient assistance for eligible patients. See the official Saxenda savings page.
- Avoid: Research peptides, unverified compounding pharmacies, and overseas online pharmacies. The FDA has documented counterfeit semaglutide circulating in the US supply chain.

Cost
List price is approximately ~$1,349/mo. With commercial insurance and a savings card, many patients pay $0–$25/month. Without insurance, expect $500–$1,400/month depending on the program. Compare cash prices on GoodRx or Cost Plus Drugs.
Key evidence
The pivotal trial for Saxenda is SCALE Obesity (NEJM, 2015): Liraglutide 3.0 mg produced ~8% mean weight loss vs ~2.6% with placebo over 56 weeks.

Frequently asked questions
How quickly does Saxenda work?
Most people notice reduced appetite within 1–2 weeks of starting Saxenda. Meaningful weight or A1c changes typically appear after 8–12 weeks at a therapeutic dose, with maximum effects between 6 and 18 months.
Will I regain weight if I stop Saxenda?
Clinical trials (STEP, SURMOUNT) show that most people regain a significant portion of lost weight within a year of stopping a GLP-1. These medications are generally considered long-term therapies, similar to blood pressure or cholesterol drugs.
Can I drink alcohol on Saxenda?
There is no absolute contraindication, but alcohol can worsen nausea and increase the risk of pancreatitis and hypoglycemia (especially if combined with insulin or sulfonylureas). Many patients report decreased desire for alcohol on GLP-1s.
Is Saxenda covered by insurance?
Coverage for weight loss is inconsistent. Some commercial plans cover it with a BMI requirement; Medicare currently does not cover GLP-1s purely for obesity. Manufacturer savings programs and self-pay options can reduce cost.
What happens if I miss a dose?
Take the missed dose the same day if you remember. If it is close to your next dose, skip it. Never double up.
Can I use Saxenda during pregnancy?
No. GLP-1 medications should be stopped at least 2 months before a planned pregnancy. They are not recommended in pregnancy or breastfeeding due to limited safety data.
