Nursing implications

Nursing assessment

• Endometriosis: Assess endometrial pain before and periodically throughout therapy.
• Fibrocystic Breast Disease: Assess breast pain, tenderness, and nodules before and monthly throughout therapy. To rule out carcinoma, mammography or cyst biopsy is recommended before and during treatment if nodules persist or enlarge.
• Hereditary Angioedema: Monitor for edematous attacks throughout therapy, especially during dosage adjustments.
• Lab Test Considerations: Monitor liver function tests periodically throughout therapy.
  • Semen volume and viscosity, sperm count, and motility determinations are recommended every 3–4 mo during treatment for hereditary angioedema, especially in adolescents.
  • May alter results of glucose tolerance or thyroid function tests. May also cause ↑ serum glucose and low-density lipoprotein concentrations and ↓ high-density lipoprotein concentrations.

Potential Nursing Diagnoses

Implementation

• In patients with endometriosis or fibrocystic breast disease, therapy should be started during menstruation or preceded by a pregnancy test. Advise patient to notify health care professional immediately if pregnancy is suspected.
• Oral: Medication may be administered with meals to minimize GI irritation.

Patient/Family Teaching

• Instruct patient to take medication exactly as directed. Take missed doses as soon as remembered, if not almost time for next dose; do not double doses.
  • Advise patient to notify health care professional if masculinizing effects occur (abnormal growth of facial hair or other body hair, deepening of the voice).
  • Advise patient to use sunscreen and protective clothing to prevent photosensitivity reactions.
  • Advise patient to use a nonhormonal form of contraception during therapy. Inform patient that amenorrhea is expected with higher doses. Instruct patient to notify health care professional if regular menstruation does not occur within 60–90 days after discontinuation of therapy or if pregnancy is suspected.
  • Emphasize the importance of routine visits to health care professional to check progress during therapy.
• Fibrocystic Breast Disease: Teach patient the correct technique for monthly breast self-exam. Instruct patient to report increase in size of nodules to health care professional promptly.

Evaluation/Desired Outcomes

• Decrease in symptoms of endometriosis. Therapy for endometriosis usually requires 3–6 mo and may extend to 9 mo to decrease symptoms.
• Relief of pain and tenderness in fibrocystic breast disease, which is usually relieved by the first month and eliminated in 2–3 mo. Elimination of nodularity usually requires 4–6 mo.
• Resolution of signs and symptoms of hereditary angioedema. Initial response in hereditary angioedema may require 1–3 mo of therapy; efforts should be made to decrease dose at 1–3-mo intervals.
