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.

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.

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.

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.

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.

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.
