Overview

â„šī¸

What is this medicine?

Isotretinoin is a strong medicine used to treat severe acne that hasn't responded to other treatments. It works by reducing the oil glands in your skin, which helps clear up acne. Because it can cause serious birth defects, it's very important for women who can get pregnant to follow strict rules, including using two forms of birth control and getting monthly pregnancy tests.

Lifestyle & Tips

  • Take with food (preferably a high-fat meal) to improve absorption.
  • Do not donate blood during treatment and for one month after stopping, due to the risk of pregnant recipients.
  • Avoid waxing for hair removal during treatment and for at least 6 months after, as it can cause skin tearing.
  • Avoid cosmetic procedures like dermabrasion or laser skin treatments during and for at least 6 months after treatment, due to increased risk of scarring.
  • Use sunscreen and protective clothing, as skin may become more sensitive to the sun.
  • Use lip balm and moisturizers regularly to combat dryness.
  • Avoid contact lenses if experiencing severe dry eyes; use lubricating eye drops.
  • Do not share this medication with anyone else.

âš•ī¸

Dose Adjustments

Renal Impairment:

Mild: No specific dose adjustment recommended, but monitor closely.
Moderate: Consider lower initial dose (e.g., 10 mg/day or 0.1 mg/kg/day) and titrate slowly.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Isotretinoin is a retinoid that acts by reducing sebaceous gland size and inhibiting sebaceous gland activity, leading to a substantial reduction in sebum production. It also inhibits the growth of Propionibacterium acnes (now Cutibacterium acnes), has anti-inflammatory effects, and normalizes follicular keratinization, preventing comedone formation.

Special Patient Groups

🤰

Pregnancy

Absolutely contraindicated. Isotretinoin is a potent human teratogen, causing severe and life-threatening birth defects (e.g., craniofacial, cardiovascular, CNS, thymic abnormalities). Females of reproductive potential must be enrolled in the iPLEDGE program and adhere to strict contraception requirements.

Trimester-Specific Risks:

First Trimester: Highest risk of severe birth defects (craniofacial, cardiovascular, CNS, thymic, ear abnormalities).
Second Trimester: Continued risk of birth defects, though potentially lower than first trimester.
Third Trimester: Risk of premature birth, low birth weight, and potential for retinoid-related adverse effects on fetal development.
🤱

Lactation

Contraindicated. It is not known if isotretinoin is excreted in human milk, but due to its high lipophilicity and potential for serious adverse reactions in the nursing infant, breastfeeding is not recommended.

Infant Risk: L5 (Contraindicated - significant documented risk to infant)
đŸ‘ļ

Pediatric Use

Approved for severe recalcitrant nodular acne in patients typically >12 years old and skeletally mature. Safety and effectiveness in children <12 years of age or prepubertal patients have not been established. Use in younger patients should be carefully considered due to potential effects on bone growth (premature epiphyseal closure).

👴

Geriatric Use

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

Clinical Information

💎

Clinical Pearls

  • Isotretinoin is a highly effective treatment for severe acne, but its use is strictly regulated due to severe teratogenicity.
  • Adherence to the iPLEDGE program is mandatory for all prescribers, pharmacies, and patients.
  • Patients should be counseled extensively on potential side effects, especially dryness, mood changes, and the importance of contraception.
  • Monthly monitoring of lipids and LFTs is crucial. Dose adjustments or temporary discontinuation may be necessary.
  • Patients should be advised to avoid blood donation during and for one month after treatment.
  • A second course of treatment can be considered if relapse occurs, typically after a break of at least 2 months.
  • The cumulative dose (120-150 mg/kg) is often a better predictor of long-term remission than daily dose or duration.
🔄

Alternative Therapies

  • Oral antibiotics (e.g., doxycycline, minocycline, azithromycin) in combination with topical retinoids and/or benzoyl peroxide for moderate to severe acne.
  • Hormonal therapies (e.g., oral contraceptives, spironolactone) for hormonal acne in females.
  • Topical retinoids (e.g., tretinoin, adapalene, tazarotene) for less severe acne.
  • Photodynamic therapy (PDT) for severe acne.
  • Dermatological procedures (e.g., chemical peels, extractions, laser therapy).
