Overview
Bennatus Expectorant is a healthcare product with Ammonium Chloride declared as its active content. It is supplied in a pack size of 90ml.
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
Bennatus Expectorant should be taken by mouth using the measuring cup or spoon provided, and the dose should not be adjusted or repeated more often than directed on the product label or by a pharmacist. It is generally taken after meals to reduce the chance of stomach upset, and plenty of fluids should be taken alongside it to help support the expectorant action. It should not be given to young children without first checking with a doctor or pharmacist.
Dosage
The typical adult dose is as stated on the product packaging or as advised by a pharmacist, usually taken several times a day and not exceeding the maximum daily dose stated on the label. Children require a lower, weight- or age-appropriate dose and a pharmacist or doctor should be consulted before giving this product to a child. Do not take more than the recommended dose in an attempt to relieve symptoms faster, as this increases the risk of side effects.
Shelf Life
Bennatus Expectorant should be used within the shelf-life period printed on the bottle or carton when unopened and stored correctly. Once opened, it is best used within the timeframe recommended by the pharmacist, and any portion of the medicine that is discoloured, has an unusual smell, or is past its expiry date should be discarded.
Storage Instructions
Store Bennatus Expectorant at room temperature below 30°C, away from direct sunlight, heat, and moisture, and keep the bottle tightly capped between uses. Keep the medicine out of reach and sight of children at all times.

What should I do if I notice side effects after using Bennatus 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.

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 Bennatus 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 Bennatus 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.

Relevant Information
Bennatus Expectorant is intended for short-term symptomatic relief of cough and should not be used continuously for more than a few days without medical review. Because Diphenhydramine can cause drowsiness, it is often more suitable for use at night, and patients should be cautious about daytime use if alertness is required, such as when driving or working with machinery.
