Why is there no information here about what Singulair 10mg Tablet is for?

This page is limited to product, safety and handling information in line with Malaysian rules on medicine information. If you want advice on whether this product suits you, book an online consultation with a doctor or pharmacist on DoctorOnCall.

How should I use Singulair 10mg Tablet?

Follow the instructions printed on the label and in the leaflet supplied with the pack, and do not exceed the stated amount or duration. Handling steps are set out in the Directions for Use section on this page.

Can I speak to a doctor or pharmacist about Singulair 10mg Tablet before I buy it?

Yes. DoctorOnCall offers online consultations with licensed doctors and registered pharmacists, so you can ask about this product, your existing medicines, or anything on the label before you place an order.

What should I do if I notice side effects after using Singulair 10mg Tablet?

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 Singulair 10mg 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 Singulair 10mg 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

Singulair 10mg Tablet is a tablet with Montelukast Sodium equivalent to Montelukast 10mg declared as its active content. It is supplied in pack sizes of 28s and 7s.

This is a non-prescription product and can be purchased without a prescription. Only product, safety and handling details are published on this page.

An online consultation with a DoctorOnCall doctor or pharmacist is available for this product, and a registered pharmacist reviews each order before dispatch to Malaysia or Singapore. Follow the directions on the label and on the leaflet inside the pack.

Directions for Use

Singulair 10mg Tablet is taken by mouth once daily, generally in the evening, with or without food, exactly as prescribed by the doctor. It should be swallowed whole and taken at around the same time each day to maintain a steady effect. Patients should continue taking it regularly even when feeling well, since it is a preventer medicine, and should not stop or adjust the dose without consulting the prescribing doctor first.

Dosage

The standard adult and adolescent (15 years and above) dose is one 10mg tablet taken once daily in the evening, as confirmed during the online consultation. Dosing for younger patients uses different Montelukast strengths and is not covered by this 10mg adult tablet. The prescribing doctor will confirm the exact dose and duration based on the individual’s asthma control or allergy severity, and any change to the regimen should only be made under medical supervision.

Storage Instructions

Store below 30°C in a dry place, away from direct light and moisture, in the original packaging until ready to use. Keep out of the sight and reach of children, and do not use tablets that have been removed from their blister and left exposed for an extended period.

Side Effects

Headache
Stomach discomfort or pain
Cough
Dizziness
Fatigue
Sore throat
Diarrhoea

Contraindications

Drug / Food Interactions

No significant food restriction, though consistent timing of the dose is recommended

Relevant Information

Montelukast is generally used as an add-on maintenance therapy for asthma and allergic rhinitis rather than a first-line or standalone rescue treatment, and its full benefit is usually seen with regular, ongoing use rather than occasional dosing. Because this is a prescription medicine, DoctorOnCall requires an online consultation so a doctor can confirm that Singulair 10mg Tablet is appropriate before it is dispensed, and periodic follow-up is recommended to monitor asthma control and watch for any mood-related side effects.
