Can I speak to a doctor or pharmacist about Sandoz Montelukast 4mg Tablet before I buy it?

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 Sandoz Montelukast 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 Sandoz Montelukast 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.

Overview

Sandoz Montelukast 4mg Tablet is supplied as a tablet, with Montelukast (as montelukast sodium) 4mg. It is supplied in pack sizes of 10s and 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

Montelukast 4mg Tablet should only be given to a child as prescribed by a doctor, following the dose, frequency, and duration instructed. It is usually taken once daily in the evening, with or without food, and can be chewed or dissolved as directed depending on the exact formulation dispensed. Do not stop giving the medicine or change the dose without consulting the prescribing doctor, even if the child’s symptoms appear to improve, as Montelukast is intended for regular, ongoing use rather than as-needed relief.

Dosage

The standard dose of Montelukast for children aged 2 to 5 years is generally 4mg once daily, taken in the evening, but the exact dose and duration must be confirmed by the prescribing doctor based on the child’s age, weight, and medical history. Do not adjust the dose or give a double dose to make up for a missed one — if a dose is missed, continue with the next scheduled dose as normal, or ask the doctor or pharmacist for guidance.

Shelf Life

Sandoz Montelukast 4mg Tablet is generally stable for up to 2 to 3 years from the date of manufacture when stored correctly and unopened. Always check the expiry date printed on the packaging before use, and do not use the medicine beyond its stated expiry date.

Storage Instructions

Store Sandoz Montelukast 4mg Tablet below 30°C in a cool, dry place away from direct sunlight and moisture. Keep the tablets in their original packaging until ready for use. Keep out of reach and sight of children, even though this medicine is intended for children, to prevent accidental double-dosing.

Contraindications

Drug / Food Interactions

Phenobarbital and rifampicin may reduce the effectiveness of Montelukast by increasing its breakdown in the body

Quick Tips
