Oraltek Sublingual Spray: Allergen Immunotherapy via Lecheng Special Access

Public reports from Boao Lecheng briefing introduces Oraltek (Inmunotek) 30,000 TU/mL solution sublingual spray, an allergen-specific immunotherapy for allergic respiratory disease via the pilot-zone special-access channel. Prescription product—not dosing advice. Confirm availability, indication, and the label with the receiving hospital.

Cause-directed, not only symptomatic

The post describes a house-dust-mite / Dermatophagoides extract spray that uses allergen-specific immunotherapy—“desensitization training”—so the immune system gradually tolerates the allergen, unlike typical symptom-relief drugs.

Who it is for (as stated)

Adults and children/adolescents aged 5+. After skin-prick and/or specific IgE confirmation, allergic rhinitis, conjunctivitis, or rhinoconjunctivitis from the matching allergen—with or without bronchial asthma—may be treated under a physician’s guidance.

Allergen components

Single allergens cited include birch, mugwort, ragweed, house-dust mite, cat/dog/horse epithelium, and Alternaria; mixes include grass pollens, tree pollens, ragweed + mugwort, and house-dust mite + flour mite. Hospital stock lists decide which SKUs are actually on site.

How it is used

Once daily, two sprays under the tongue or around the mouth; each spray is 100 μL (3,000 TU). Avoid eating, drinking, brushing, or rinsing for 30 minutes before and after. Course is set by an allergy specialist—typically 3 months to 5 years in the post—and must be supervised. Child/adolescent dose equals the adult dose. Manufacturer video does not replace the leaflet.

Mechanism and cautions

Sublingual delivery is said to modulate the allergen-specific response and induce specific IgG; the clinical mechanism is not fully elucidated. The post cites >10 years’ use in multiple countries without a special risk signal—monitoring and a prescription remain mandatory.

Prescription-only: an experienced allergy clinician must prescribe and supervise. If year-round symptoms persist, or there is little improvement after the first pollen season, reassess. For cross-border care, verify Lecheng special-import access, stock, and a written estimate.

The Boao Lecheng International Medical Tourism Pilot Zone, approved by the State Council in February 2013, pilots franchised medical care aiming for “three synchronizations” of technology, equipment, and drugs with international standards.
