Why is there no information here about what Aerius 5mg Tablet is for?

This page is limited to product, safety and handling information in line with Malaysian rules on medicine information. If you want advice on whether this product suits you, book an online consultation with a doctor or pharmacist on DoctorOnCall.

How should I use Aerius 5mg Tablet?

Follow the instructions printed on the label and in the leaflet supplied with the pack, and do not exceed the stated amount or duration. Handling steps are set out in the Directions for Use section on this page.

Can I speak to a doctor or pharmacist about Aerius 5mg Tablet 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.

What should I do if I notice side effects after using Aerius 5mg Tablet?

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

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 Aerius 5mg Tablet 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 5mg Tablet 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.

Overview

Directions for Use

Aerius 5mg Tablet is taken once daily, with or without food, and swallowed whole with a glass of water. It can be taken at any time of day that is convenient, but taking it at the same time each day helps maintain steady symptom control. Do not chew or crush the tablet unless advised to do so by a pharmacist.

Dosage

The usual dose for adults and adolescents aged 12 years and above is one 5mg tablet once daily. For chronic urticaria, treatment is often continued for as long as symptoms persist, under periodic review, while for seasonal allergic rhinitis it may be used only during the relevant allergy season. Do not exceed the recommended dose.

Shelf Life

Aerius 5mg Tablet typically has a shelf life of around 36 months from the date of manufacture when stored unopened under the recommended conditions. Always check the expiry date printed on the blister strip and outer carton before use, and do not use the tablets beyond this date.

Relevant Information

Aerius 5mg Tablet is widely used across Malaysia and Singapore for both seasonal allergic rhinitis and longer-term management of chronic hives. Unlike the combination Aerius D-12 product, it does not contain a decongestant, so it does not carry the same cardiovascular precautions and remains suitable for self-selection as an over-the-counter option for most adults and adolescents. Anyone experiencing signs of a severe allergic reaction, such as difficulty breathing or swelling of the face and throat, should seek emergency medical care rather than relying on this tablet alone.
