Is Mounjaro available in Singapore?

Mounjaro (tirzepatide) is registered in Singapore as a prescription-only medicine and is listed in the Singapore National Drug Formulary (NDF). Registered Mounjaro presentations include the 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg strengths, including pre-filled pen formulations. The NDF lists tirzepatide products as generally available across several public healthcare institutions in Singapore. However, this does not mean that every Mounjaro strength is always in stock or immediately available at every pharmacy, clinic or hospital.

The NDF specifically states that its general availability information does not reflect actual inventory and may change according to supply and healthcare institution requirements. Therefore, a particular Mounjaro dose being temporarily unavailable at one pharmacy or healthcare institution should not automatically be interpreted as a nationwide Mounjaro shortage in Singapore. Patients should confirm current stock and supply arrangements with their healthcare provider or pharmacy before arranging treatment or collecting their prescription.

Availability can also vary between Mounjaro strengths. For example, the 2.5mg starting dose may be available while another dose is temporarily out of stock, or a higher maintenance dose may have different supply conditions. This is particularly relevant for patients who are gradually increasing their tirzepatide dose under medical supervision.

If your prescribed Mounjaro strength is unavailable, do not change to another strength, increase or reduce your dose, or switch to another GLP-1 medicine without speaking to your doctor. Your doctor or pharmacist can advise whether you should wait for the prescribed strength, obtain it through another authorised supply channel, or consider an appropriate alternative based on your treatment plan.

Why can Mounjaro availability vary in Singapore?

• High demand: Demand for tirzepatide and other GLP-1 medicines can affect the availability of particular strengths.
• Strength-specific supply: Mounjaro is available in several dose strengths, so stock can differ between 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg.
• Healthcare institution: Stock and supply arrangements can differ between hospitals, polyclinics, clinics and pharmacies.
• Prescription requirements: Mounjaro is a prescription-only medicine in Singapore and must be supplied under appropriate medical supervision.
• Supply and distribution changes: Pharmaceutical supply can change over time because of manufacturing, distribution and demand conditions.
• Treatment-stage requirements: Patients may require different Mounjaro strengths as their treatment progresses, so availability of the prescribed dose is more important than simply finding another strength in stock.

Where can I check Mounjaro availability in Singapore?

The Singapore National Drug Formulary provides information about the general availability of tirzepatide products in participating public healthcare institutions. However, the NDF does not provide real-time pharmacy inventory. Patients should therefore contact the relevant hospital, polyclinic, clinic or pharmacy directly to confirm whether their prescribed Mounjaro strength is currently available.

For patients considering Mounjaro for weight management, it is also important to understand whether tirzepatide is appropriate for their individual circumstances before arranging treatment. Read our guide on who Mounjaro is suitable for to learn more about treatment eligibility and factors your doctor may consider.

Can I buy Mounjaro from an online pharmacy if it is unavailable locally?

Mounjaro is a prescription-only medicine, so patients should only obtain it through legitimate healthcare and pharmacy channels with the appropriate prescription and medical oversight. HSA has warned consumers about the risks of obtaining prescription medicines and injectable weight-management products from unauthorised online or overseas sources, where products may be counterfeit, improperly stored or otherwise unsuitable for use.

If you are considering obtaining Mounjaro from outside Singapore, the order must also be subject to the applicable Singapore requirements for importing and receiving prescription medicines. Do not assume that a product being sold online is automatically authorised for supply or import into Singapore.

What should I do if my Mounjaro dose is out of stock?

If your prescribed Mounjaro strength is temporarily unavailable, speak with your doctor or pharmacist before making any changes. Do not use a different Mounjaro strength as a substitute, take additional injections to compensate, or switch to another GLP-1 medicine without medical advice. Your healthcare professional can assess your current treatment stage and advise you on the safest option based on your prescribed dose and available supply.

For patients ordering Mounjaro through DoctorOnCall, availability may depend on the prescribed strength, prescription verification, current stock and applicable delivery requirements. Temperature-sensitive medicines also require appropriate handling during delivery. Always check the current product listing and ordering information before placing an order.

The starting and maintenance dosage of Mounjaro (Tirzepatide) 2.5mg/dose KwikPen Solution for injection in pre-filled pen 1 pen varies depending on your individual condition and treatment response. Most patients begin at 2.5mg once weekly, which allows the body to adjust to the medication. After a period—which your doctor will determine—the dosage may be increased in a stepwise fashion (e.g., to 5mg, 7.5mg, etc.), based on how your blood sugar responds and how well you tolerate the treatment.

It’s crucial not to self-adjust the dose without consulting your doctor. Always follow the exact plan set out by your diabetes care team. Regular checkups and monitoring are key to managing your condition effectively.

Using Mounjaro (Tirzepatide) 2.5mg/dose KwikPen Solution for injection in pre-filled pen 1 pen is simple once you get the hang of it.
