This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.
Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.
Directions for Use
Mounjaro KwikPen is injected subcutaneously (under the skin) into the abdomen, thigh, or upper arm, rotating the injection site with each dose. Each pen is for single use only and should be disposed of after one injection, even if some solution remains. Patients should be trained by a healthcare professional on correct injection technique before using the pen independently. If a dose is missed and it has been less than 4 days since the missed dose, it should be taken as soon as possible; if more than 4 days have passed, the missed dose should be skipped and the next dose taken on the regular scheduled day – do not inject two doses close together.
Dosage
Mounjaro is usually started at a low dose and increased gradually every 4 weeks according to the patient’s response and tolerability, up to a maximum recommended dose. The 12.5mg/dose KwikPen is injected once weekly, on the same day each week, at any time of day, with or without food. The exact starting dose, titration schedule, and target maintenance dose must be determined and adjusted by the prescribing doctor based on individual blood glucose control and tolerability – patients should never change their dose or switch strengths without medical advice.
Shelf Life
Use this product before the expiry date stated on the packaging. Do not use the medicine if the expiry date has passed.
Storage Instructions
Store unused Mounjaro KwikPens in a refrigerator (2°C to 8°C); do not freeze, and discard the pen if it has been frozen. Once in use, a pen may be kept below 30°C or in a refrigerator for up to 21 days, away from direct light and heat, and out of reach of children. Always keep the pen cap on when not in use.

Can I stop taking Mounjaro 12.5mg/dose KwikPen Solution for Injection in Pre-filled Pen on my own?
No. Speak to your doctor before stopping, pausing or changing the dose, even if you feel well or think you no longer need the medicine.
How do I get a prescription for Mounjaro 12.5mg/dose KwikPen Solution for Injection in Pre-filled Pen?
Customers in Malaysia can complete an online consultation with a DoctorOnCall doctor, who decides whether a prescription is appropriate, or upload a valid prescription already issued by their own doctor.
Orders going to Singapore are dispatched from Malaysia as an international delivery, so you need to hold a valid prescription or doctor’s letter for the medicine. Check the consultation and prescription upload options shown at checkout for your delivery address before placing the order.
How long will delivery take?
Within Malaysia, standard delivery takes 3 to 5 working days. Same-day delivery is available in the Klang Valley for orders placed before 12pm; orders placed after 12pm arrive by the end of the next day.
Orders to Singapore are sent as international deliveries and take 5 to 9 working days. A lump-sum shipping and handling fee applies to every overseas delivery and is shown at checkout.
What payment methods can I use?
Customers in Malaysia can pay by FPX online banking, credit or debit card (Visa and Mastercard), and supported e-wallets including Touch ‘n Go eWallet, GrabPay and ShopeePay.
FPX and local e-wallets are tied to Malaysian bank and wallet accounts, so if your delivery address is in Singapore, use the payment options displayed at checkout for that address rather than assuming the same list applies.
Can Mounjaro 12.5mg/dose KwikPen Solution for Injection in Pre-filled Pen be delivered to Singapore?
Yes. DoctorOnCall ships to Singapore as an international order dispatched from Malaysia, arriving in 5 to 9 working days with a lump-sum shipping and handling fee.
Singapore’s Health Sciences Authority (HSA) allows personal imports of up to three months’ supply of a medicine for your own use or an immediate family member’s, as long as it contains no controlled drugs, psychotropic substances or prohibited items. Keep the product in its original labelled packaging and keep a copy of your prescription or doctor’s letter with it. Quantities above three months’ supply, and medicines containing controlled substances, require prior HSA approval.
Is Mounjaro 12.5mg/dose KwikPen Solution for Injection in Pre-filled Pen registered with the authorities?
Products listed on DoctorOnCall are registered with Malaysia’s Ministry of Health for supply in Malaysia, and each pack carries its MAL registration number.
An order delivered to Singapore arrives as a personal import of a Malaysia-registered product; HSA product registration is not required for personal-use quantities, but it is also not the same as a product registered for sale in Singapore. If you need a locally registered Singapore product, buy it from a pharmacy in Singapore.
Who do I contact if there is a problem with my order?
DoctorOnCall’s customer care team handles order, delivery and product queries through the contact channels on the site, including WhatsApp and the online help centre.
For deliveries to Singapore, allow more time before chasing an order than you would for a local Malaysian delivery, as the parcel passes through customs clearance and tracking updates can appear later in the journey.
