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


  • Do not inject intravenously.
  • Allergenic extracts may cause severe life-threatening systemic reactions, including the rare occurrence of anaphylaxis or death. Systemic reactions include: generalized skin erythema, urticaria, pruritus, angioedema, rhinitis, wheezing, laryngeal edema and hypotension. Other adverse reactions include: nausea, emesis, abdominal cramps, and diarrhea.
  • Intended for use only by physicians who are experienced in the administration of allergenic extracts. Initial dose must be based on skin test.
  • 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 medical conditions that reduce their ability to survive a systemic reaction.
