Overview

Benatussil Expectorant contains Ammonium Chloride and is presented as a healthcare product. It is supplied in a pack size of 120ml.

It is classified as a non-prescription medicine, so no prescription is needed to order it. Under Malaysian rules for medicine information, this page carries product, safety and handling information only.

You can consult a doctor or pharmacist online on DoctorOnCall about this product before or after you order. Every order is checked by a registered pharmacist before it is delivered. Always read the label and the leaflet supplied with the pack.

Directions for Use

Benatussil Expectorant should be taken orally using the measuring cup or spoon supplied with the product, following the dose and frequency printed on the label or advised by a pharmacist. It is best taken after food to minimise the chance of stomach discomfort, and adequate fluid intake should be maintained to support the loosening of mucus. Do not give to infants or very young children without first checking with a doctor or pharmacist.

Dosage

The standard adult dose is as indicated on the product packaging, generally taken multiple times daily up to the stated maximum, while children require a reduced, age-appropriate dose that should be confirmed with a pharmacist before use. The dose should not be increased beyond what is recommended in an attempt to speed up relief, as doing so raises the risk of side effects without added benefit.

Shelf Life

Benatussil Expectorant should be used within the shelf-life period stated on the packaging when kept unopened and stored under the recommended conditions. After opening, use within the period advised by the pharmacist and discard the product if it shows discolouration, an unusual odour, or has passed its expiry date.

Storage Instructions

Store Benatussil Expectorant at room temperature below 30°C, protected from direct sunlight, heat, and moisture, with the cap tightly closed after each use. Always keep out of reach and sight of children.

What pack sizes does Benatussil Expectorant come in?

It is supplied in a pack size of 120ml. Choose the pack size you need from the options shown on this page before adding the item to your cart.

Why is there no information here about what Benatussil Expectorant 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 Benatussil Expectorant?

Use it exactly as stated on the pack label, without changing the amount or how often you use it. If anything on the label is unclear, check with a pharmacist before the first use, and read the Directions for Use section on this page.

Can I speak to a doctor or pharmacist about Benatussil Expectorant 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.

How should I store Benatussil Expectorant?

Store Benatussil Expectorant at room temperature below 30°C, protected from direct sunlight, heat, and moisture, with the cap tightly closed after each use. Always keep out of reach and sight of children. Keep it in its original pack and do not use it after the expiry date printed on the packaging.

What should I do if I notice side effects after using Benatussil Expectorant?

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you. Seek medical care immediately for signs of a severe reaction such as difficulty breathing, swelling of the face, lips or throat, or a widespread rash. 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 Benatussil Expectorant 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 Benatussil Expectorant 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.
