Key Information
Tirzepatide is now officially available in Singapore for prescription under the supervision of licensed doctors.
At Sire, an MOH-registered telemedicine clinic, patients can now safely access Tirzepatide in Singapore for both type 2 diabetes and clinically guided medical weight loss.
Globally, Tirzepatide has gained recognition as one of the most effective, evidence-based treatments for long-term weight management and metabolic improvement. Its dual hormone mechanism makes it a significant leap beyond older GLP-1 medications like Wegovy and Saxenda.
This comprehensive guide explains everything you need to know about Tirzepatide in Singapore — how it works, who qualifies, expected results, cost, side effects, and how to start your treatment through Sire’s telemedicine programme.

What is Tirzepatide and How It Works
Tirzepatide is a dual GIP and GLP-1 receptor agonist — a next-generation injectable medication that mimics two natural hormones that regulate blood sugar, appetite, and metabolism.
Tirzepatide activates both GLP-1 and GIP receptors. This dual mechanism enhances appetite control and boosts insulin efficiency for deeper, more sustainable weight loss.
How It Works:
- Slows digestion, allowing you to feel full longer
- Reduces cravings and hunger, helping you eat less naturally
- Improves glucose control, stabilising energy levels
- Enhances fat metabolism, leading to steady and significant body fat reduction
- Improves insulin sensitivity, making it easier for your body to burn fat efficiently
Clinical studies have shown up to 22.5% total body weight loss over 72 weeks, outperforming all other available weight loss injectables to date.
For many adults, Tirzepatide not only leads to significant weight loss but also reverses prediabetes, lowers cholesterol, and reduces cardiovascular risk – improving overall health.
Availability and Regulation in Singapore
Tirzepatide (marketed as Mounjaro®) is approved and available in Singapore for type 2 diabetes management under the Health Sciences Authority (HSA).
Licensed doctors can also prescribe it for medical weight management in individuals who meet clinical criteria, such as elevated BMI (overweight) or metabolic risk.

Expert Insight: Dr Bosty Chan on the Future of Weight Loss Medications
Dr Bosty Chan, Medical Director at Sire, was recently featured in The Straits Times for his expert commentary on Singapore’s growing adoption of advanced weight loss medications.
In his interview, Dr Chan highlighted how telemedicine has transformed safe, accessible obesity management in Singapore — allowing licensed doctors to prescribe and monitor an individual remotely, without compromising clinical quality.
“These new medications are changing the way we treat obesity — shifting the focus from stigma to science. When prescribed responsibly, they help patients take control of their metabolic health in a safe, structured way.”
