Overview
Asthator 4mg Tablet is supplied as a tablet, with Montelukast Sodium equivalent to Montelukast 4mg. It is supplied in a pack size of 30s.
No prescription is required for this product, as it is a non-prescription medicine. This page is limited to product, safety and handling information.
If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.
Directions for Use
Asthator 4mg Tablet is usually given once daily in the evening, as prescribed by the child’s doctor, and can be taken with or without food. If the tablet is chewable or dispersible, follow the specific instructions given by the pharmacist on how to administer it to a young child; this medicine should be given consistently every day, even when the child feels well, unless the doctor advises otherwise.
Dosage
The 4mg strength is intended for young children within the age range specified by the prescribing doctor, and the exact dose and duration should follow the doctor’s instructions precisely. It is not a fast-acting rescue treatment, so it will not relieve a sudden asthma attack, and a reliever inhaler should still be available as directed by the child’s doctor.
Shelf Life
Asthator 4mg Tablet should be used within the shelf life printed on the packaging when stored correctly. Do not use the tablets after the expiry date, and any unused or expired medicine should be disposed of safely rather than kept for later use.
Storage Instructions
Store Asthator 4mg Tablet at room temperature, away from direct light, heat, and moisture, in its original packaging until it is time for the next dose. Keep the medicine well out of the reach of children, as this and similar chewable formulations can be mistaken for sweets.

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you.

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 Asthator 4mg Tablet 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 Asthator 4mg Tablet 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.
