Introduction
Saxenda (liraglutide 3 mg) is a GLP-1 receptor agonist approved for chronic weight management in adults with obesity or overweight with at least one weight-related condition. It is given as a once-daily subcutaneous injection that reduces appetite and slows gastric emptying. The dose is gradually increased over five weeks to minimize gastrointestinal side effects.
Week-by-week timeline
Starting Dose: 0.6 mg
Begin at 0.6 mg once daily. Common side effects include nausea, constipation, and decreased appetite. Inject at the same time each day. Some patients begin to notice reduced hunger immediately.
Increase to 1.2 mg
Dose increases to 1.2 mg. Nausea may intensify briefly. Appetite suppression becomes more noticeable. Some patients begin losing weight. Stay well-hydrated.
Increase to 1.8 mg
Dose increases to 1.8 mg. GI symptoms often begin improving. Weight loss becomes more consistent as appetite is significantly reduced.
Increase to 2.4 mg
Dose increases to 2.4 mg. Most patients tolerate this well with fewer GI side effects. Energy levels may improve as diet quality improves.
Target Dose: 3.0 mg
Full therapeutic dose of 3.0 mg is reached. This is the maintenance dose. Clinical trials show average weight loss of 5-10% of body weight after 6-12 months.
Long-Term Weight Management
Consistent weight loss expected with lifestyle changes. If less than 4% weight loss after 16 weeks at 3 mg, discuss alternatives with your doctor.
When to call your doctor
Contact your healthcare provider if you experience:
- Severe abdominal pain radiating to the back (possible pancreatitis)
- Neck lump, hoarseness, or difficulty swallowing (possible thyroid tumor)
- Severe allergic reaction: difficulty breathing, facial swelling
- Persistent resting heart rate greater than 100 bpm
- New or worsening thoughts of self-harm
- Upper right abdominal pain with fever or jaundice (gallbladder problems)
Tips for getting started
Pair Saxenda with a reduced-calorie diet and increased physical activity. Eating smaller, low-fat meals reduces nausea. Rotate injection sites among abdomen, thigh, and upper arm. Weigh yourself weekly rather than daily to track progress. If nausea is severe, ask your doctor about slowing the dose escalation schedule.
