Overview
Sunward Sunex Cough Syrup contains Diphenhydramine Hydrochloride and is presented as a syrup. 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
Shake the bottle well before use and measure the dose using the measuring cup or spoon provided rather than an ordinary household spoon. Take the syrup after meals to reduce the chance of stomach upset, and follow the dosing schedule printed on the product label or as advised by a pharmacist or doctor, without exceeding the recommended frequency within 24 hours.
Dosage
Dosage depends on age and the specific product strength, so always check the label or ask a pharmacist for the correct amount for adults, children, or the elderly. As a general guide for combination diphenhydramine-based cough syrups, adults typically take a measured dose every 4 to 6 hours as needed, children require a lower age- or weight-adjusted dose, and use in infants under 2 years should only be under medical advice.
Shelf Life
Sunward Sunex Cough Syrup is generally stable for up to 2 to 3 years from the date of manufacture when unopened and stored correctly. Always check the expiry date printed on the bottle and discard any syrup that is past its expiry date or has changed in colour, smell, or consistency after opening.
Storage Instructions
Store below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed when not in use. Keep this medicine out of the sight and reach of children, and avoid storing it in the bathroom or near a sink where humidity is high.

How should I use Sunward Sunex Cough Syrup?
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 Sunward Sunex Cough Syrup 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 Sunward Sunex Cough Syrup?
Store below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed when not in use. Keep this medicine out of the sight and reach of children, and avoid storing it in the bathroom or near a sink where humidity is high. 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 Sunward Sunex Cough Syrup?
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 Sunward Sunex Cough Syrup 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 Sunward Sunex Cough Syrup 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.
