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

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

Reported reactions are listed in the Side Effects section on this page.

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 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 Asthator 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

Asthator 10mg Tablet is supplied as a tablet, with Montelukast Sodium equivalent to Montelukast 10mg. 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.

Directions for Use

Asthator 10mg Tablet is typically taken once daily in the evening, with or without food, exactly as prescribed by the doctor. It should be taken consistently every day, even during symptom-free periods, and should not be used as a rescue medicine for sudden breathlessness; a fast-acting reliever inhaler should still be kept on hand as directed.

Dosage

The 10mg strength is intended for adult and adolescent patients as determined by the prescribing doctor, who will set the exact dose and treatment duration based on the severity of asthma or allergic rhinitis. Patients should not adjust the dose on their own and should continue treatment for as long as advised, since the full preventive benefit builds up with regular use.

Shelf Life

Asthator 10mg Tablet should be used within the shelf life printed on the packaging when stored under proper conditions. Do not use the tablets after the expiry date shown on the box, and safely dispose of any unused or expired medicine.
