Acarizax® Sublingual Tablet for House Dust Mite Allergy

What Acarizax® Is and How It Works

Acarizax® is a prescription sublingual immunotherapy tablet for house dust mite (HDM) allergy. It treats persistent allergic rhinitis with or without conjunctivitis, and it may benefit HDM‑allergic asthma under the direction of a specialist. Many people compare Acarizax price, especially when paying without insurance, because treatment is taken daily for years.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; prescriptions are reviewed by licensed pharmacists before dispensing.

Acarizax uses standardized HDM allergen extract (12 SQ‑HDM) in an oral lyophilisat that dissolves under the tongue. Regular exposure trains the immune system to react less to HDM allergens. Over time, this can reduce symptom severity, lower medication needs, and improve quality of life. The usual regimen is one tablet once daily, taken long term. First dose is given under medical supervision to monitor for allergic reactions.

The tablet is placed under the tongue where allergens contact oral immune cells. Immunotherapy shifts the response away from IgE‑mediated reactivity and increases blocking antibodies such as IgG4. Benefits build gradually, with clearer effects after several months and best outcomes when therapy continues for about three years.

Many patients take Acarizax tablets alongside intranasal steroids or antihistamines at the start, then taper symptomatic medicines as control improves per prescriber advice.

Dosage and Usage

• Initiation: The first dose is administered in a clinical setting with 30 minutes of observation.
• Daily dose: One Acarizax 12 SQ HDM tablet once daily, placed under the tongue to dissolve.
• Administration: With dry hands, remove a tablet from the blister immediately before use. The tablet is placed under the tongue and allowed to dissolve completely.
• Swallowing/food: Avoid swallowing for about one minute. Do not eat or drink for five minutes after administration.
• Oral health: Postpone doses during active mouth ulcers, severe oral inflammation, or after dental procedures until healed per prescriber guidance.
• Asthma stability: Do not start during an acute asthma exacerbation. Patients with persistent asthma should be stable on controller therapy.
• Missed dose: If one daily dose is missed, take the next dose at the usual time. After several missed days, consult the prescriber before restarting.
• Emergency plan: An epinephrine auto‑injector may be prescribed; patients should be trained on its use.

• Storage: Keep tablets in the original blister until use. Protect from moisture.
• Temperature: Follow the product label. Many lots require refrigerated storage at 2–8 °C. Do not freeze.
• Room‑temperature excursions: Short room‑temperature periods may be permitted; check the package leaflet or ask the pharmacist about allowable time out of refrigeration.
• Travel: Use an insulated pouch with gel packs for longer trips. Keep blisters together with the carton for identification.
• Handling: Do not cut or split the tablet. Open blisters with dry hands immediately before dosing.
• Shipping: Orders are sent with prompt, express, cold‑chain shipping to protect product quality.

Benefits and Savings

Acarizax helps reduce nasal congestion, sneezing, and itchy or watery eyes triggered by HDM. It can improve asthma control in HDM‑sensitized patients whose asthma is not severe or uncontrolled. Daily sublingual dosing avoids injections and clinic visits typical of allergy shots, and many find the home routine convenient. In clinical studies, local mouth and throat symptoms were common at the start but usually eased within weeks.

Compared with typical U.S. pharmacy pricing, ordering from Canada can offer 60–80% savings. If paying without insurance, many patients compare Acarizax cost across 30‑ and 90‑tablet supplies to lower the monthly spend. Multi‑month orders or bulk promotions can reduce per‑month costs, and our reorder reminders help maintain continuity.

We source through licensed, vetted partner pharmacies internationally to ensure authentic brand medications, a broad selection, and fair, affordable pricing.

Pack sizes vary by market; Acarizax 90 can be a convenient three‑month supply. There is no Acarizax generic at this time. Many Acarizax review summaries note the convenience of daily tablets and the trend toward fewer rescue medications over time.

Side Effects and Safety

• Common: mouth itching or tingling
• Throat irritation or tightness
• Lip, tongue, or mouth swelling (usually mild)
• Ear itching
• Hoarseness
• Nausea, abdominal discomfort, heartburn
• Headache

Serious reactions are uncommon but can include systemic allergy, severe laryngeal edema, asthma exacerbations, and eosinophilic esophagitis (EoE). Treatment should be stopped and urgent care sought if symptoms of anaphylaxis occur (trouble breathing, throat swelling, dizziness). Acarizax is contraindicated in severe or uncontrolled asthma, a history of severe systemic reactions to SLIT, and active or chronic EoE.

Onset Time

Local mouth or throat sensations often appear on day one and lessen within one to three weeks. Nasal and eye symptom relief may be noticed after 8–14 weeks, with steadier improvement by 3–6 months. Asthma‑related benefits usually take several months. Best results are seen when treatment continues for about three years, with benefits persisting beyond completion for many patients.

Compare With Alternatives

Odactra contains the same HDM allergen dose (12 SQ‑HDM) and is a U.S. brand of the same therapy class. Selection often depends on local availability, pricing, and prescriber preference.

Subcutaneous immunotherapy (allergy shots) is another disease‑modifying option for HDM. Shots are administered in a clinic, starting with frequent visits that taper over time. Some patients prefer in‑clinic oversight, while others prefer the convenience of daily sublingual dosing at home.

Symptomatic therapies such as intranasal corticosteroids, oral antihistamines, and leukotriene receptor antagonists relieve symptoms but do not retrain the immune system. Many patients use them alongside Acarizax during the first months, then adjust as control improves.

Combination Therapy

• Intranasal corticosteroids for seasonal or perennial congestion.
• Second‑generation oral antihistamines for sneezing and itch.
• Asthma controllers (inhaled corticosteroids with or without LABA) for HDM‑driven asthma.
• Saline rinses to reduce nasal allergen load and dryness.
• Dose adjustments for other medicines are not typically required, but asthma rescue and controller plans should be reviewed to avoid undertreatment.

Patient Suitability and Cost-Saving Tips

Good candidates include adolescents and adults with confirmed HDM sensitization and ongoing symptoms despite avoidance and standard symptomatic therapy. Therapy should begin when asthma is stable and not during an acute flare. Do not use in severe or uncontrolled asthma, chronic oral inflammation, or a history of severe SLIT reactions. Initiation during pregnancy is usually avoided; those who become pregnant on stable therapy should discuss continuation with their prescriber.

People with frequent oral ulcers, recent dental surgery, or active EoE are not ideal candidates. Children younger than the approved age range should use pediatric‑appropriate options guided by a specialist. The product is an oral lyophilisat; patients with swallowing difficulties should discuss administration steps in advance.

To manage Acarizax cash price and out of pocket expense, consider a 90‑tablet supply to reduce shipping frequency and per‑month costs. You can enable reorder reminders in your account. Ordering is available online, and customer‑service chat is available during posted office hours if questions arise about packs or shipping.
