Adverse Reactions/Side Effects

Central nervous system

  • dizziness


  • ↑ transaminases


  • injection site reactions (most frequent)


  • fever


Drug-Drug interaction

May ↓ antihypertensive response to ACE inhibitors.


Subcutaneous (Adults >18yr) 30 mg may be repeated in 6 hr, not to exceed 3 injections/24 hr.


Solution for subcutaneous injection: 10 mg/mL in 3 mL syringe (30 mg/syringe)

Nursing implications

Nursing assessment

  • Assess for symptoms of hereditary angioedema (submucosal or subcutaneous swelling) before and following treatment.
  • Lab Test Considerations: May cause ↑ serum transaminases.

Potential Nursing Diagnoses

Ineffective breathing pattern (Indications)


  • Additional doses may be administered with at least 6 hrs between injection if response is inadequate or symptoms recur. Do not administer more that 3 doses in 24 hr.
  • Subcutaneous: Inject into abdominal area using the 25 gauge needle provided. Pinch fold of skin about 2–4 inches from belly button and inject at a 45°–90° angle. Avoid areas with scars or that are bruised, swollen, or painful. Do not use a different needle. Solution is clear and colorless; do not administer solutions that are discolored or contain particulate matter.

Patient/Family Teaching

  • Instruct patient in recognizing symptoms of hereditary angioedema and correct technique for self-administration and disposal of equipment.
  • Caution patient to seek medical attention immediately after injection if laryngeal swelling occurs.
  • May cause tiredness, drowsiness, and dizziness. Caution patient to avoid driving, and other activities requiring alertness until response to medication is known.
  • Advise patient to notify health care professional if fever, dizziness, or rash occur.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
  • Advise female patient to notify health care professional if pregnancy is planned or suspected or if breastfeeding.

Evaluation/Desired Outcomes

  • Resolution of signs and symptoms of an acute attack of hereditary angioedema.
