FDA Box Warning

• Patients with acute promyelocytic leukemia (APL) are at high risk in general and may have severe adverse reactions. Give drug under supervision of physician experienced in managing patients with acute leukemia, in facility with laboratory and supportive resources sufficient to monitor drug tolerance and protect and maintain patient compromised by drug toxicity.

• Before using drug, physician must conclude that possible benefit to patient outweighs the following known adverse effects:

• Retinoic acid-APL (RA-APL syndrome), which may be accompanied by impaired myocardial contractility, hypotension, and progressive hypoxemia. Several patients have died with multiorgan failure. Syndrome generally occurs during first month of therapy (in some cases, after first dose).

• Leukocytosis at presentation or evolving rapidly during drug therapy. Patients with high white blood cell (WBC) at diagnosis (above 5 × 109/L) have increased risk of further rapid rise in WBC counts. Rapidly evolving leukocytosis raises risk of life-threatening complications.

• Teratogenic effects. Drug therapy during pregnancy carries high risk of severe birth defects. Nonetheless, if drug is best available treatment for pregnant woman or woman of childbearing potential, ensure that she has received full information and warnings of risk to fetus and of risk of possible contraception failure, and has been taught to use two reliable contraceptive methods simultaneously during therapy and for 1 month afterward.


Unknown. Thought to cause differentiation of promyelocytic leukemic blast cells, leading to apoptosis (cell shrinkage and death) and cancer remission.

Patient monitoring

Monitor cardiovascular status. Stay alert for signs and symptoms of arrhythmias, MI, and heart failure.

Closely monitor liver and kidney function tests. Watch for evidence of hepatitis and renal failure.

Monitor coagulation studies. Watch closely for DIC and hemorrhage.

• Evaluate respiratory status. Stay alert for indications of pulmonary hypertension and respiratory insufficiency.

• Frequently assess lipid panel and CBC with white cell differential.

Patient teaching

• Instruct patient to take oral doses with food.

Teach patient to recognize and immediately report serious adverse reactions.

• Tell patient he will undergo regular blood testing during oral therapy.

• Instruct patient using topical form to gently wash face with mild soap, pat skin dry, and then wait 20 to 30 minutes before applying. Advise him to apply to face in evening, using only enough to cover entire affected area lightly and only for prescribed duration.

• Caution patient to avoid OTC acne drugs and extreme weather conditions (such as wind and cold). Urge him to adhere to prescribed skin care and sunlight avoidance programs when using topical form.

• Tell patient using topical form that transient burning, erythema, peeling, pruritus, and stinging may occur. Advise him to notify prescriber if these symptoms become severe.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, foods, and behaviors mentioned above.

Nursing implications

Nursing assessment

  • Assess skin prior to and periodically during therapy. Note number and severity of cysts, degree of skin dryness, erythema, and itching. Response to frequency of application and dose concentration is variable and should be closely monitored. Transient worsening of acne may occur at initiation of therapy. This may be due to the effects of tretinoin on deep, previously undetected lesions and is not a reason to discontinue therapy.

Potential Nursing Diagnoses

Risk for impaired skin integrity (Indications,  Side Effects)
Disturbed body image (Indications)


  • Topical: Tretinoin should be applied once a day before bedtime. Cover the entire area lightly. Wash hands immediately after application.
  • Liquid: Apply with fingertip, gauze pad, or cotton swab. Do not saturate gauze pad or cotton swab to the extent that medication runs on to unaffected area.
  • Gel: Excessive application results in “pilling” of gel, which minimizes overapplication of tretinoin.
    • May induce severe local edema and peeling at the site of application. If this occurs, tretinoin may be used less frequently, or discontinued temporarily or completely.

Patient/Family Teaching

  • Instruct patient to apply tretinoin as directed. Application may cause a transient feeling of warmth and a slight stinging. Avoid application near eyes, mouth, angle of the nose, and mucous membranes. Do not apply excessive amounts, because this may cause redness, peeling, or discomfort and will not improve results. If a dose is missed, omit and apply next dose at regularly scheduled time; do not double doses.
  • Explain to patient that a temporary worsening of acne may occur at beginning of therapy.
  • Advise patient to consult with health care professional before using other acne preparations while using tretinoin. Normal use of cosmetics is permissible, but area to be treated must be thoroughly cleansed prior to application. Medicated or abrasive soaps or cleansers, soaps and cosmetics that have a strong drying effect, and products that have a high concentration of alcohol, astringents, spices, or lime also may worsen dry skin.
  • Caution patient to use sunscreens with an SPF of at least 15, and protective clothing to prevent photosensitivity reactions. Consult health care professional about sunscreen; some sunscreens may worsen acne. Patients should be taught to minimize exposure to sunlight and sunlamps, and if sunburned to cease tretinoin treatment until fully recovered. Other weather extremes (wind, cold) also may be irritating to skin.

Evaluation/Desired Outcomes

  • Decrease in the number and severity of cysts in severe acne. Therapeutic results are usually seen in 2–3 wk but may require 6 wk for optimal results. Once results are satisfactory, maintain therapy with less frequent applications or other dosage forms.
  • Decreased skin roughness, hyperpigmentation, and wrinkling due to photoaging.
