Overview
Acarizax Oral Lyophilized Tablet is supplied as a tablet, with Standardized allergen extract of Dermatophagoides pteronyssinus and Dermatophagoides farinae (house dust mite), active ingredient. It is supplied in a pack size of 30s.
No prescription is required for this product, as it is a non-prescription medicine. This page is limited to product, safety and handling information.
If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.
Directions for Use
Acarizax Oral Lyophilized Tablet must only be used after an online medical consultation and prescription through DoctorOnCall, and the first dose must be taken under direct medical supervision because of the risk of an allergic reaction. Using clean, dry fingers, the tablet is placed under the tongue where it dissolves within seconds without water, and saliva should not be swallowed for at least 1 minute; food and drink should be avoided for 5 minutes afterwards. Subsequent doses are usually taken once daily at home exactly as directed by the prescribing doctor.
Dosage
Treatment is usually started with one tablet taken once daily under medical observation in a clinical setting, after which the same once-daily dose is continued at home as prescribed. A course of at least 3 years of continuous daily treatment is generally recommended to achieve a lasting reduction in house dust mite allergy symptoms, and the specific duration and any dose adjustments should always be guided by the prescribing doctor.
Shelf Life
Acarizax Oral Lyophilized Tablet typically has a shelf life of around 24 to 36 months from the date of manufacture when stored unopened under the recommended conditions in its original blister packaging. Always check the expiry date printed on the blister and outer carton before use, and do not use the tablets beyond this date.
Storage Instructions
Store Acarizax Oral Lyophilized Tablet below 25°C in a dry place, protected from moisture, and keep it in the original blister until immediately before use, as the tablet is fragile and moisture-sensitive. Store out of the reach and sight of children.

Drug / Food Interactions
Concurrent use with medicines that suppress the immune system, such as long-term oral corticosteroids or other immunosuppressants, may reduce the effectiveness of immunotherapy and should be discussed with the prescribing doctor

Relevant Information
Acarizax Oral Lyophilized Tablet is a specialist-initiated, long-term treatment rather than a quick symptom reliever, and ongoing medical supervision is an essential part of therapy given the small but real risk of allergic reactions, including rare severe reactions requiring emergency treatment. Doctors on DoctorOnCall assess a patient’s asthma control, allergy history, and general suitability before prescribing, and will advise on what to do in the event of a missed dose, an intercurrent illness, or a suspected reaction. Patients starting Acarizax should have a clear understanding of the multi-year commitment involved and should not stop or restart treatment without first consulting their doctor.

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.
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.
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.
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.
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.
