What ACARIZAX® is used for
ACARIZAX® contains an allergen extract from house dust mites. It comes in a tablet form which is intended to be absorbed in the body by placing it under the tongue.
ACARIZAX® is for the treatment of house dust mite allergy that is characterised by rhinitis (sneezing, runny or itchy nose, nasal congestion) in adults and adolescents aged 12 years and above. It is also for the treatment of house dust mite related allergic asthma in adults.
ACARIZAX® is not recommended for use in children below 12 years of age.
ACARIZAX® works by increasing your immune tolerance to house dust mites leading to reduction in the severity of your allergic symptoms over time.
Before starting treatment, the doctor will check if ACARIZAX® is suitable for you by performing the appropriate blood and/or skin prick tests.
ACARIZAX® is only available with a prescription from the doctor.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
