Itulazax

Betula verrucosa, the active ingredient in Itulazax, is an allergen extract presented as a sublingual formulation for sublingual use. It is indicated for the management of allergic rhinitis, allergic conjunctivitis and allergic asthma caused by birch pollen in patients with documented sensitivity to Betula verrucosa.

GNH USA supplies Itulazax as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Itulazax is used in allergy immunotherapy to reduce symptoms caused by birch pollen exposure. - Allergic rhinitis: reduces nasal congestion, sneezing and itching associated with birch pollen allergy. - Allergic conjunctivitis: alleviates eye redness, tearing and itching triggered by birch pollen. - Allergic asthma: helps control bronchial hyper‑responsiveness and wheezing related to birch pollen exposure.

Adverse reactions to Itulazax are generally mild and related to its immunologic activity. Common Side Effects: - Oral itching: mild irritation of the mouth or throat after sublingual administration. - Swelling of lips or tongue: transient localized edema. - Nasal congestion: temporary blockage of nasal passages. - Headache: mild tension‑type headache. Serious or Rare Side Effects: - Anaphylaxis: severe, systemic allergic reaction requiring immediate medical attention. - Angioedema: rapid swelling of face, lips or airway. - Severe asthma exacerbation: worsening of bronchospasm after dosing.

Before prescribing Itulazax, clinicians should consider several safety and handling precautions. - Assess sensitivity: confirm documented IgE‑mediated sensitivity to Betula verrucosa before initiating therapy. - Initiate under supervision: first dose should be administered in a medical setting equipped for emergency management. - Monitor for reactions: observe patients for at least 30 minutes after each dose for signs of systemic allergy. - Contraindications: avoid use in individuals with a history of severe anaphylaxis to birch pollen or other allergens. - Pregnancy and lactation: use only if the potential benefit outweighs potential risk; data are limited. - Store at ambient temperature: keep below 25°C in the original container, protect from moisture and direct sunlight.

Itulazax may interact with other medications that affect immune responses or allergic reactions. Major Interactions (Avoid): - Beta‑blockers: may reduce the effectiveness of emergency treatment for anaphylaxis. - ACE inhibitors: can increase the risk of angioedema when combined with allergen exposure. Moderate Interactions (Monitor Closely): - Antihistamines: may mask early signs of an allergic reaction, requiring careful monitoring. - Corticosteroids: concurrent use may alter immune tolerance development. - Immunotherapy agents: overlapping allergen exposure could enhance systemic reactions.
