INDICATIONS

Allergenic extracts are indicated for skin test diagnosis and treatment (immunotherapy) of patients with seasonal and perennial allergies.

IMPORTANT SAFETY INFORMATION

WARNING: SEVERE ALLERGIC REACTIONS

  • Allergenic extracts can cause severe life-threatening systemic reactions, including anaphylaxis.
  • Do not administer allergenic extracts to patients with severe, unstable, or uncontrollable asthma.
  • Observe patients in the office for at least 30 minutes following treatment. Emergency measures and personnel trained in their use must be available immediately in the event of a life-threatening reaction.
  • Immunotherapy may not be suitable for patients with certain underlying medical conditions that may reduce their ability to survive a systemic allergic reaction.
  • Allergenic extracts may not be suitable for patients receiving medications such as beta-blockers that may make them unresponsive to epinephrine or inhaled bronchodilators.

Do not inject intravenously. Initial dose should be based on skin test reactivity.

The most common adverse reactions include localized erythema, itching, swelling, tenderness, and pain. Systemic adverse reactions include generalized skin erythema, urticaria, pruritus, angioedema, rhinitis, wheezing, chest tightness, laryngeal edema, and hypotension.

INDICATIONS

Non-Standardized Allergenic Extracts: Allergenic extracts are indicated for skin test diagnosis of patients with a clinical history of allergies to one or more of the specific allergens and treatment for reduction of allergen-induced allergic symptoms confirmed by positive skin tests or in vitro testing for allergen-specific IgE antibodies. Food extracts have not been proven safe or effective in allergen immunotherapy.

Short Ragweed Pollen Allergenic Extract and Short and Giant Ragweed Pollen Mix Allergenic Extract: Short Ragweed Pollen Allergenic Extract and Short and Giant Ragweed Pollen Mix Allergenic Extract are indicated for skin test diagnosis of patients with a clinical history of allergy to ragweed pollen (Short Ragweed or Short and Giant Ragweed pollen), and immunotherapy for the reduction of ragweed pollen-induced allergic symptoms confirmed by positive skin test or by in vitro testing for pollen-specific IgE antibodies for Short and/or Giant Ragweed pollen.

Standardized Cat Hair Allergenic Extract: Standardized Cat Hair Allergenic Extract is indicated for skin test diagnosis of patients with a history of allergy to cats and treatment of cat hair-induced allergic asthma, rhinitis and conjunctivitis when avoidance is not possible.
