Itulazax

Betula verrucosa, the active ingredient in Itulazax, is an allergen extract presented as a sublingual formulation for sublingual use. It is employed to treat allergic rhinitis and allergic conjunctivitis caused by birch (Betula) pollen in sensitised individuals. The product is manufactured according to EU standards and is prescribed by healthcare professionals.

GNH USA supplies Itulazax as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, adhering to Good Distribution Practice to ensure product integrity across global supply chains.

Itulazax is used in allergy immunotherapy to address birch pollen‑induced conditions.

- Allergic rhinitis: reduces nasal congestion, sneezing and itching, improving daily function. - Allergic conjunctivitis: alleviates eye itching, redness and tearing associated with birch pollen exposure. - Seasonal birch pollen allergy: promotes long‑term immune tolerance, decreasing symptom severity over time.

Sublingual administration of Itulazax may be associated with local and systemic reactions.

Common Side Effects: - Oral itching or mild throat irritation. - Mild gastrointestinal discomfort such as nausea. - Transient swelling of the lips or tongue. - Localized nasal irritation.

Serious or Rare Side Effects: - Anaphylaxis, a severe systemic allergic reaction requiring immediate medical attention. - Severe asthma exacerbation triggered by the extract. - Cardiovascular collapse or hypotension in rare cases.

Prior to initiating Itulazax therapy, clinicians should consider several safety measures. - Sensitivity assessment: confirm birch pollen IgE sensitisation through skin testing or specific IgE measurement. - Medical supervision: administer first dose under physician observation to monitor for systemic reactions. - Asthma control: avoid use in patients with uncontrolled asthma or recent severe exacerbations. - Concomitant medications: evaluate beta‑blocker use, as it may mask anaphylaxis signs. - Pregnancy and lactation: prescribe only if benefit outweighs potential risk, due to limited data. - Store at room temperature: keep in original container, protect from moisture and direct sunlight.

Itulazax can interact with certain medications, influencing safety or efficacy.

Major Interactions (Avoid): - Beta‑blockers: may blunt response to epinephrine during anaphylaxis. - ACE inhibitors: increase risk of severe angio‑edema when combined with allergen exposure. - Immunosuppressants: may reduce the immunomodulatory effect of the extract.

Moderate Interactions (Monitor Closely): - Antihistamines: may lessen local oral side effects but do not prevent systemic reactions. - Corticosteroids: concurrent use may alter immune response, requiring dose adjustment.
