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
Shake the bottle well before each use and measure the dose accurately using the measuring cup or spoon provided, rather than an ordinary household spoon. Sunward Sunthorphan 15mg/5ml Syrup can be taken with or without food, and should be used at the lowest effective dose for the shortest time needed to control the dry cough, generally not exceeding a few days without medical review.
Dosage
Dosing depends on age and body weight and should follow the instructions on the product label or a pharmacist’s advice. As a general guide for adults, a dose is typically taken every 6 to 8 hours as needed, up to a maximum daily amount stated on the packaging; children require a correspondingly lower, weight-based dose, and this product should not be given to very young children without specific pharmacist or doctor guidance. Do not exceed the maximum recommended daily dose.
Shelf Life
Sunward Sunthorphan 15mg/5ml Syrup typically remains effective for around 24 to 36 months from the date of manufacture when unopened; always check the expiry date printed on the bottle or carton, and discard any syrup remaining after the in-use period stated on the label once opened.
Storage Instructions
Store below 30°C in a cool, dry place away from direct sunlight, and keep the bottle tightly capped after each use. Keep this medicine out of the reach and sight of children, and do not store it in the refrigerator unless the label specifically states to do so.

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 Sunthorphan 15mg/5ml 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 Sunthorphan 15mg/5ml 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.

A dry cough that does not improve, worsens, or is accompanied by breathing difficulty, high fever, or chest pain may indicate a more serious underlying condition and should be assessed by a doctor rather than managed with cough syrup alone. Parents giving this syrup to children should always follow age-appropriate dosing instructions and avoid giving multiple cough and cold products at the same time.
