Can I speak to a doctor or pharmacist about Aerius 0.5 mg/ml Syrup before I buy it?

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you.

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 Aerius 0.5 mg/ml 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 Aerius 0.5 mg/ml 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.

Directions for Use

Aerius 0.5 mg/ml Syrup should be measured carefully using the oral syringe or measuring cup provided with the product, not a household spoon, to ensure an accurate dose. It can be given with or without food, once daily, and the bottle should be shaken gently before each use if instructed on the packaging. Always follow the age-specific dosing guidance on the label or as advised by a pharmacist or doctor.

Dosage

Dosing of Aerius 0.5 mg/ml Syrup is based on age: children aged 1 to 5 years are typically given 2.5ml (1.25mg) once daily, children aged 6 to 11 years are typically given 5ml (2.5mg) once daily, and adults and adolescents aged 12 years and above are typically given 10ml (5mg) once daily. A pharmacist should be consulted to confirm the correct dose for a child’s specific age and weight before starting treatment.

Shelf Life

Aerius 0.5 mg/ml Syrup typically has a shelf life of around 24 to 36 months from the date of manufacture when unopened, and a shorter in-use period once the bottle has been opened, as stated on the packaging. Always check the expiry date printed on the bottle and outer carton before use.

Storage Instructions

Store Aerius 0.5 mg/ml Syrup below 30°C in a cool, dry place away from direct sunlight, and do not freeze. Keep the bottle tightly closed after each use, discard any unused syrup after the in-use period stated on the packaging, and store out of the reach and sight of children.

Relevant Information

Aerius 0.5 mg/ml Syrup is a commonly used paediatric antihistamine in Malaysia and Singapore, valued for its once-daily, non-sedating profile that fits well with school routines. Parents should always confirm dosing with a pharmacist based on the child’s exact age, and should seek prompt medical attention if a child shows signs of a severe allergic reaction, such as difficulty breathing or swelling of the face, lips, or throat, rather than relying on the syrup alone.
