Acarizax® Tablets for Dust Mite Allergy

What Acarizax Is and How It Works

Acarizax® is a prescription sublingual immunotherapy for house dust mite allergy. It helps retrain your immune system to react less to mite allergens over time. This page explains how the treatment works, who may benefit, and how you can order with US delivery from Canada even if you pay without insurance.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

This medicine contains standardized house dust mite allergen extract in an oral lyophilisate that dissolves under the tongue. Daily dosing exposes your immune system to controlled amounts of allergen. Over time, this can reduce nasal and ocular symptoms linked to dust mite exposure. The class is designed for long-term use under a prescriber’s care. First doses are typically supervised so you can be monitored for allergic reactions.

Acarizax lyophilisate is taken at home after the first observed dose. It is not a rescue treatment for sudden symptoms. Patients continue their usual symptomatic medicines as directed while this therapy begins to work. Always follow the official product label and your prescriber’s instructions.

Who It’s For

This treatment is for patients with dust mite–induced allergic rhinitis, with or without conjunctivitis, confirmed by testing and history. Some regions also include use in certain patients with mite-related allergic asthma alongside standard control therapy; your prescriber will determine if this applies to you. The therapy should be started and overseen by a clinician experienced with allergy immunotherapy.

People with severe or uncontrolled asthma, eosinophilic esophagitis, or a history of severe systemic reactions to allergen immunotherapy should not use this class. Avoid starting during an acute respiratory infection or while you have mouth sores, recent dental surgery, or oral inflammation. Tell your prescriber about pregnancy, plans to become pregnant, or breastfeeding. Discuss heart or lung conditions, and any prior anaphylaxis.

Dosage and Usage

One Acarizax tablet is taken once daily, as directed by your prescriber. The first dose is usually given under medical supervision. Place the tablet under the tongue and allow it to dissolve completely. Do not chew or swallow it whole. Avoid food or drink for a few minutes after dosing. Wash your hands before and after handling the tablet.

Continue your existing allergy medications unless your clinician advises otherwise. If you experience persistent throat swelling, difficulty swallowing, or breathing symptoms after a dose, seek urgent care. Some people receive epinephrine training for rare severe reactions; your prescriber will advise if this is appropriate.

Immunotherapy is long-term. Benefit builds gradually with daily adherence. Do not change your schedule or stop without discussing it with your prescriber. Refer to the official label for full dosing instructions, age limits, and supervision requirements.

Strengths and Forms

This therapy is supplied as oral lyophilisate tablets in unit-dose blisters. Availability can vary by market and by pharmacy inventory. Commonly published options include:

• Acarizax 12 SQ-HDM tablets
• Also available as 90 SQ-HDM in some regions

Your prescriber will select the presentation that matches your indication and local labeling. Packaging sizes and manufacturers’ designs may differ between countries.

Missed Dose and Timing

If you miss a day, take the next dose at the usual time the following day. Do not double up. After longer gaps, your prescriber may want you to restart under supervision, depending on your history and the gap length. Keep dosing at approximately the same time each day to support routine and reduce the chance of omissions. If you have active mouth ulcers, significant oral inflammation, or a recent dental procedure, wait until your mouth heals before resuming and check in with your clinician.

Storage and Travel Basics

Keep tablets in the original blister pack until use. Store at room temperature away from moisture and direct light. Do not freeze. Keep out of reach of children and pets. If a blister is damaged, use a different intact dose.

When traveling, carry doses in your hand luggage along with a copy of your prescription and your prescriber’s instructions. If your clinician has provided an epinephrine auto-injector, keep it with you. For border crossings or flights, bring documentation that identifies the therapy and your dosing schedule. Avoid storing tablets in hot cars or damp bathrooms. If you have questions about handling during extreme temperatures, ask your pharmacist; temperature-controlled handling when required is used for sensitive items, but these tablets are typically shelf-stable when kept properly.

Benefits

This medicine targets the underlying allergic response to house dust mites rather than only masking symptoms. With consistent use, the treatment may reduce nasal congestion, sneezing, and itchy or watery eyes. Many patients appreciate at-home dosing after the first supervised administration. Daily, fixed dosing helps establish a routine. Over time, some patients may rely less on short-acting symptom relievers, as guided by their prescriber. Individual responses vary, and continued adherence is important.

Side Effects and Safety

• Mouth or tongue itching
• Throat irritation or tightness
• Mild mouth swelling
• Ear or lip itching
• Nausea or stomach discomfort
• Headache

Reactions usually start early and are often mild to moderate. Serious reactions are rare but can include anaphylaxis, severe throat swelling, or asthma worsening. Stop the dose and seek emergency care if you have breathing trouble, faintness, or fast-spreading hives. Eosinophilic esophagitis has been reported with sublingual immunotherapy; new or worsening difficulty swallowing or chest pain should be evaluated promptly. People with asthma should maintain good baseline control and have an action plan.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements you use. Beta-blockers may reduce the effectiveness of epinephrine used to treat severe reactions. Certain blood pressure medicines such as ACE inhibitors warrant discussion. Use caution if you have active oral infections or inflammation, or if you recently had dental procedures. Alcohol may worsen mouth irritation in some people.

Discuss any history of mast cell disorders, chronic urticaria, or prior severe systemic reactions to allergy immunotherapy. Review pregnancy and breastfeeding considerations in advance. Do not start or stop asthma control medicines without guidance. Keep rescue inhalers available if you have asthma, and monitor control closely.

What to Expect Over Time

Early on, local mouth or throat symptoms are common and usually settle with continued dosing. Symptom relief may emerge gradually as your immune system adapts to regular allergen exposure. You may notice seasonal or environmental triggers feel less intense over time. Adherence is key. Use simple prompts, such as phone reminders or pairing the dose with a daily routine like brushing your teeth. Stay in touch with your clinician for periodic check-ins and to discuss any side effects or flare patterns.

If your prescriber recommends ongoing therapy, that decision is based on your symptom history, control goals, and label guidance. The full course is individualized. Avoid setting fixed expectations; your clinician will monitor progress and safety.

Compare With Alternatives

Allergen immunotherapy addresses the cause of dust mite allergy. Symptom-control options can complement or, for some patients, substitute for immunotherapy. A steroid nasal spray like Mometasone Nasal Spray reduces nasal inflammation and congestion. A leukotriene receptor antagonist such as Montelukast may help nasal and lower-airway symptoms for selected patients. Your prescriber can help decide which approach fits your diagnosis, asthma status, and treatment goals.

Availability and Substitutions

Stock can vary by strength and pack size. If a selected option is unavailable, your prescriber may recommend another allergen immunotherapy or a symptomatic regimen. Ask about Acarizax generic availability where you live; for many biologic allergen extracts, direct generics may not exist. Do not switch to another product without professional guidance, as standardization and indications differ by extract and region.

Patient Suitability and Cost-Saving Tips

Good candidates have confirmed house dust mite allergy and a history of symptoms despite environmental control and standard therapies. Those with uncontrolled asthma or certain esophageal conditions are not candidates. If you and your clinician decide to start, ask about multi-month quantities if permitted by your prescription, which can reduce per-fill fees. Set refill reminders to avoid gaps in therapy. Combine your order with other approved items when possible to optimize fulfilment costs. Review your plan’s out-of-network policies if you later submit receipts.
