Implementation

  • Topical: For face and scalp: Apply 0.015% gel to affected area once daily for 3 consecutive days. For trunk and extremities: Apply 0.05% gel to affected area once daily for 2 consecutive days.
    • Open a new tube of gel for each application, then discard. Store tubes in refrigerator; do not freeze. After spreading evenly over area, allow to dry for 15 min. Do not cover with bandages or other closed dressings. Wash hands immediately after applying. Do not apply to mouth, eyes, or vaginal areas. Avoid transfer of applied drug to other areas. Avoid washing and touching area for at least 6 hr after application. After 6 hrs, may wash with mild soap.

Patient/Family Teaching

  • Instruct patient on correct technique for application. Do not apply right after taking a shower or less than 2 hrs before bedtime. Do not apply more than needed to cover treatment area. Using too much or for too long may cause severe skin reactions.
  • Inform patient that gel application may cause local skin reactions (mild redness, flaking, scaling, crusting, swelling). Notify health care professional if reaction is severe or if blisters, pus, ulcers, or breakdown of skin 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 patients to notify health care professional if pregnancy is planned or suspected or if breastfeeding.

Evaluation/Desired Outcomes

  • Resolution of actinic keratoses.
