Overview

Retinol is a vitamin analog that is FDA approved for the treatment of acne vulgaris. Common adverse reactions include hypopigmentation, hyperpigmentation, skin erythema.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

  • RETIN-A is indicated for topical application in the treatment of acne vulgaris. The safety and efficacy of the long-term use of this product in the treatment of other disorders have not been established.
  • RETIN-A Gel, Cream or Liquid should be applied once a day, before retiring, to the skin where acne lesions appear, using enough to cover the entire affected area lightly. Liquid: The liquid may be applied using a fingertip, gauze pad, or cotton swab. If gauze or cotton is employed, care should be taken not to oversaturate it to the extent that the liquid would run into areas where treatment is not intended. Gel: Excessive application results in “pilling” of the gel, which minimizes the likelihood of over application by the patient.
  • Application may cause a transitory feeling of warmth or slight stinging. In cases where it has been necessary to temporarily discontinue therapy or to reduce the frequency of application, therapy may be resumed or frequency of application increased when the patients become able to tolerate the treatment.
  • Alterations of vehicle, drug concentration, or dose frequency should be closely monitored by careful observation of the clinical therapeutic response and skin tolerance.
  • During the early weeks of therapy, an apparent exacerbation of inflammatory lesions may occur. This is due to the action of the medication on deep, previously unseen lesions and should not be considered a reason to discontinue therapy.
  • Therapeutic results should be noticed after two to three weeks but more than six weeks of therapy may be required before definite beneficial effects are seen.
  • Once the acne lesions have responded satisfactorily, it may be possible to maintain the improvement with less frequent applications, or other dosage forms.
  • Patients treated with RETIN-A (tretinoin) acne treatment may use cosmetics, but the area to be treated should be cleansed thoroughly before the medication is applied.

Postmarketing Experience

  • The skin of certain sensitive individuals may become excessively red, edematous, blistered, or crusted. If these effects occur, the medication should either be discontinued until the integrity of the skin is restored, or the medication should be adjusted to a level the patient can tolerate.

To date, all adverse effects of RETIN-A have been reversible upon discontinuance of therapy

Drug Interactions

There is limited information regarding Retinol Drug Interactions in the drug label.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): C

  • Oral tretinoin has been shown to be teratogenic in rats when given in doses 1000 times the topical human dose. Oral tretinoin has been shown to be fetotoxic in rats when given in doses 500 times the topical human dose.
  • Topical tretinoin has not been shown to be teratogenic in rats and rabbits when given in doses of 100 and 320 times the topical human dose, respectively (assuming a 50 kg adult applies 250 mg of 0.1% cream topically). However, at these topical doses, delayed ossification of a number of bones occurred in both species. These changes may be considered variants of normal development and are usually corrected after weaning. There are no adequate and well-controlled studies in pregnant women. Tretinoin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.


Pregnancy Category (AUS):

  • Australian Drug Evaluation Committee (ADEC) Pregnancy Category

There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Retinol in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Retinol during labor and delivery.

Nursing Mothers

  • It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when RETIN-A is administered to a nursing woman.

Pediatric Use

There is no FDA guidance on the use of Retinol with respect to pediatric patients.

Geriatic Use

There is no FDA guidance on the use of Retinol with respect to geriatric patients.

Gender

Hepatic Impairment

There is no FDA guidance on the use of Retinol in patients with hepatic impairment.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Retinol in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Retinol in patients who are immunocompromised.

Administration and Monitoring

Administration

Monitoring

  • Alterations of vehicle, drug concentration, or dose frequency should be closely monitored by careful observation of the clinical therapeutic response and skin tolerance.

IV Compatibility

There is limited information regarding IV Compatibility of Retinol in the drug label.

Overdosage

  • If medication is applied excessively, no more rapid or better results will be obtained and marked redness, peeling, or discomfort may occur. Oral ingestion of the drug may lead to the same side effects as those associated with excessive oral intake of Vitamin A
