What Is Zepbound and What Is It Used For?

Zepbound (tirzepatide) is a groundbreaking prescription medication designed for weight management and the treatment of obstructive sleep apnea (OSA) in adults with obesity. It belongs to a unique class of drugs known as dual GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptor agonists.

FDA-Approved Uses

• Chronic weight management in adults with a BMI indicating obesity or overweight who also have at least one related condition (e.g., hypertension, type 2 diabetes).
• Treatment of moderate to severe obstructive sleep apnea in adults with obesity.

Zepbound mimics hormones that regulate appetite and glucose, slowing gastric emptying and increasing feelings of fullness. This leads to reduced calorie intake and sustainable weight loss when paired with a healthy lifestyle.

Its dual-receptor mechanism gives it a potential edge over traditional GLP-1–only medications, offering broader benefits in blood sugar control, appetite suppression, and metabolic support.

Zepbound Dosage Schedule and Titration

Zepbound is introduced using a gradual titration schedule to help your body adjust and reduce side effects like nausea or gastrointestinal discomfort.

For Weight Management:

• Weeks 1–4: 2.5 mg weekly
• After Week 4: Increase by 2.5 mg every 4 weeks
• Maintenance Range: 5 mg to 15 mg once weekly
• Maximum Dose: 15 mg per week

For Obstructive Sleep Apnea:

• Same titration schedule begins at 2.5 mg weekly
• Target Maintenance Dose: 10–15 mg weekly

Important: Never adjust your dose without medical guidance. Faster titration can increase side effects without improving results.
