Overview

â„šī¸

What is this medicine?

Isotretinoin is a strong medicine used to treat very severe acne that hasn't responded to other treatments. It works by reducing the amount of oil your skin makes and helps prevent clogged pores. Because it's so strong, it has serious side effects, especially if you get pregnant while taking it.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Isotretinoin is a retinoid that acts by reducing sebaceous gland size and inhibiting sebaceous gland function, thereby decreasing sebum production. It also inhibits the growth of Propionibacterium acnes (now Cutibacterium acnes) and has anti-inflammatory properties. It normalizes follicular keratinization, preventing comedone formation.

Special Patient Groups

🤰

Pregnancy

Absolutely contraindicated. Isotretinoin is a potent human teratogen. Even a single dose can cause severe birth defects.

Trimester-Specific Risks:

First Trimester: Extremely high risk of severe and life-threatening birth defects (e.g., craniofacial, cardiovascular, CNS, thymic abnormalities).
Second Trimester: High risk of severe birth defects.
Third Trimester: High risk of severe birth defects.
🤱

Lactation

Contraindicated. It is not known if isotretinoin is excreted in human milk, but due to its potential for serious adverse reactions in nursing infants, breastfeeding is not recommended during treatment and for at least one month after stopping.

Infant Risk: High risk of serious adverse effects, including potential for teratogenicity if absorbed by infant.
đŸ‘ļ

Pediatric Use

Safety and efficacy not established in pediatric patients under 12 years of age. Use in adolescents (12-17 years) is common for severe nodular acne, with dosing similar to adults. Growth plate closure should be monitored in younger adolescents.

👴

Geriatric Use

Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Not commonly used in this population for acne. Use with caution due to potential for increased susceptibility to adverse effects (e.g., bone effects, lipid abnormalities).

Clinical Information

💎

Clinical Pearls

  • iPLEDGE program compliance is mandatory for all patients, prescribers, and pharmacies. No exceptions.
  • Two forms of effective contraception must be used by female patients of childbearing potential, starting one month before, during, and for one month after treatment.
  • Patients should be counseled extensively on potential psychiatric side effects, including depression and suicidal ideation. Any new or worsening symptoms warrant immediate discontinuation and psychiatric evaluation.
  • Dryness of skin, lips, and eyes is almost universal. Advise patients on frequent use of moisturizers, lip balm, and artificial tears.
  • Avoid blood donation during and for one month after treatment due to teratogenic risk.
  • Patients should avoid vigorous physical activity that could lead to muscle or joint injury, as isotretinoin can cause musculoskeletal pain and elevated CPK.
🔄

Alternative Therapies

  • Oral antibiotics (e.g., doxycycline, minocycline, azithromycin)
  • Topical retinoids (e.g., tretinoin, adapalene, tazarotene)
  • Topical antibiotics (e.g., clindamycin, erythromycin)
  • Benzoyl peroxide
  • Hormonal therapies (e.g., oral contraceptives, spironolactone for females)
  • Photodynamic therapy
