Liraglutide Dosing: 0.6 to 3.0mg Weight Loss Schedule

Liraglutide is an FDA-approved GLP-1 receptor agonist with 97% homology to native human GLP-1 — one of the most extensively studied peptide therapies for both type 2 diabetes and weight management. Unlike many peptides on this site, liraglutide has well-established FDA-approved dosing. This is not medical advice — work with your prescriber.

Quick Reference: Community Protocol

Liraglutide is not in the standard cheat sheet — this uses FDA-approved dosing as the protocol.

5-week titration schedule (weight loss):

• Week 1: 0.6 mg daily
• Week 2: 1.2 mg daily
• Week 3: 1.8 mg daily
• Week 4: 2.4 mg daily
• Week 5+: 3.0 mg daily

Cycling Details

Liraglutide for weight management is intended for long-term continuous use — no cycling. The 5-week titration is mandatory: each 0.6 mg increment allows GLP-1 receptors in the GI tract to adapt, dramatically reducing nausea and vomiting.

If 3.0 mg is not tolerated, maintain at the highest tolerated dose. If nausea is severe at any step, stay at the current dose for an extra week before increasing. Weight regain typically occurs upon discontinuation — the SCALE trial ran 56 weeks with continued benefit.

Missed dose: If less than 12 hours late, inject as usual. If more than 12 hours, skip and resume next day. Never double dose.

Lyophilized Vial Reconstitution (Research Use)

For compounding pharmacies or research-grade liraglutide in lyophilized form:

Math: 5,000 mcg / 2 mL = 2,500 mcg/mL. 600 mcg / 2,500 = 0.24 mL = 24 units. Higher doses require large draw volumes — a 10 mg vial with 2 mL BAC water (5 mg/mL) gives more practical volumes.

Routes of Administration

Subcutaneous (only approved route): Abdomen (most common, best absorption), thigh, or upper arm. Rotate sites within the same region. Pinch skin fold, insert at 90 degree angle, hold 6 seconds before withdrawing.

Pre-filled pen use: New needle for each injection. Prime before first use (dial 0.6 mg, point up, press until drop appears). No reconstitution needed.

Where These Numbers Come From

Liraglutide has one of the strongest clinical evidence bases of any peptide therapy.

The landmark SCALE trial (3,731 patients, 56 weeks) showed 8.0% average weight loss with liraglutide 3.0 mg vs 2.6% with placebo. 63.2% of patients lost 5%+ body weight (Pi-Sunyer et al., 2015). The SCALE Diabetes trial (846 patients with T2D) showed 6.0% weight loss with significant HbA1c improvement (Davies et al., 2015).

The LEADER cardiovascular outcomes trial (9,340 patients, 3.8 years) demonstrated a 13% reduction in major adverse cardiovascular events and 22% reduction in cardiovascular death (Marso et al., 2016). A comprehensive review confirmed efficacy across multiple populations and the importance of the titration schedule (Mehta et al., 2017).

Stacking Protocols

Do NOT combine with other GLP-1 RAs (semaglutide, tirzepatide) — overlapping mechanisms and increased GI side effects. Sulfonylureas require dose reduction (hypoglycemia risk). Insulin requires careful adjustment.

Side Effects & Safety

• Nausea — 39% (most common, peaks during dose escalation, improves after 4-8 weeks)
• Diarrhea — 21%
• Constipation — 19%
• Vomiting — 16%
• Headache — 14%
• Pancreatitis — rare (<0.5%) but requires immediate discontinuation
• Gallbladder disease — increased with rapid weight loss
• Thyroid C-cell tumors — boxed warning based on rodent studies; contraindicated with MTC/MEN2 history

Managing GI side effects: Slow titration (most effective), smaller meals, stay hydrated, avoid high-fat meals, consider extending any dose step by an extra week if needed.

Frequently Asked Questions

What is the standard liraglutide dose for weight loss?

3.0 mg subcutaneous daily, reached through a mandatory 5-week titration: 0.6 mg, then increase by 0.6 mg each week.

How long does liraglutide take to work?

Appetite suppression begins within 1-2 weeks. Clinically meaningful weight loss (5%+) typically by 12-16 weeks. Average 8% loss at 56 weeks in the SCALE trial.

Can I skip the titration schedule?

No — skipping dramatically increases nausea, vomiting, and treatment discontinuation. Each step allows GLP-1 receptors to adapt.

What's the difference between diabetes and weight loss dosing?

Same molecule. 1.2-1.8 mg daily for type 2 diabetes, up to 3.0 mg daily for weight management.

Should I take liraglutide in the morning or evening?

Either works — just be consistent. Many prefer morning dosing to manage initial nausea during waking hours.

What are the most common side effects?

Nausea (39%), diarrhea (21%), constipation (19%), vomiting (16%). These are dose-dependent and improve with proper titration over 4-8 weeks.
