Overview
Sunward Sunizine 5mg/5ml Syrup contains Cetirizine 5mg per 5ml and is presented as a syrup. It is supplied in a pack size of 60ml.
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 each use and measure the dose accurately using the measuring cup or syringe provided, rather than a household spoon. Sunward Sunizine 5mg/5ml Syrup can be given with or without food, at approximately the same time each day, following the age-appropriate dose printed on the packaging or advised by a pharmacist or doctor.
Dosage
Dosing depends on the child’s age and should strictly follow the instructions on the product label. As a general guide, younger children typically receive a smaller dose once daily, while older children may take a slightly higher dose, up to the maximum stated for their age group. This syrup is not intended for infants below the minimum age stated on the packaging unless specifically directed by a doctor.
Shelf Life
Sunward Sunizine 5mg/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 Sunizine 5mg/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 Sunizine 5mg/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.

Relevant Information
Allergic symptoms in children that are severe, associated with breathing difficulty, facial or throat swelling, or widespread hives may indicate a more serious allergic reaction requiring urgent medical attention rather than home management with an antihistamine syrup alone. Parents should keep a record of known allergies and inform their pharmacist or doctor of any other medications the child is taking.
