Overview

What is this medicine?

Claravis (isotretinoin) is a strong medicine used to treat very severe acne that hasn't responded to other treatments. It works by reducing the oil your skin makes and helping to prevent clogged pores. It has serious side effects, especially birth defects, so it's only used under strict conditions.

How to Use This Medicine

Taking Your Medication Correctly

To ensure you get the most benefit from your medication, follow these guidelines:

Take your medication exactly as directed by your doctor. Read all the information provided with your prescription and follow the instructions carefully.
Some medications should be taken with food, while others should be taken on an empty stomach. If you're unsure, consult with your pharmacist for guidance on the best way to take your medication.

Continue taking your medication as prescribed by your doctor or healthcare provider, even if you start to feel better.
You will typically receive a one-month supply of medication at a time.
It's common for skin conditions to appear worse before they start to improve with treatment.

Lifestyle & Tips

  • Do NOT become pregnant while taking this medicine or for one month after stopping it. Use two reliable forms of birth control.
  • Do NOT donate blood during treatment and for one month after stopping, as pregnant women could receive your blood.
  • Avoid sun exposure and use sunscreen (SPF 30+) and protective clothing, as skin will be more sensitive to sunburn.
  • Avoid waxing for hair removal during treatment and for at least 6 months after stopping, as it can cause severe skin tearing.
  • Avoid cosmetic procedures like dermabrasion or laser skin treatments during and for at least 6 months after treatment due to risk of scarring.
  • Do NOT take vitamin A supplements, as this can increase side effects.
  • Avoid alcohol, as it can increase triglyceride levels.
  • Use lip balm, moisturizer, and eye drops regularly to manage dryness.

Adult Dosing

Standard Dose: 0.5 to 1 mg/kg/day divided into two doses for 15 to 20 weeks
Dose Range: 0.5 - 1 mg

Condition-Specific Dosing:

severe recalcitrant nodular acne: Initial dose 0.5 mg/kg/day. May increase to 1 mg/kg/day if severe disease or if initial dose is well-tolerated and response is inadequate. Cumulative dose of 120-150 mg/kg is often associated with long-term remission.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Isotretinoin is a retinoid that acts by reducing sebaceous gland size and inhibiting sebaceous gland activity, thereby decreasing sebum production. It also inhibits the growth of Propionibacterium acnes (now Cutibacterium acnes), normalizes follicular keratinization, and possesses anti-inflammatory properties. These combined actions reduce comedogenesis and inflammation associated with acne.
📊

Rationale: Rare reports of blood dyscrasias.

Timing: Before starting therapy.

📊

Routine Monitoring

Pregnancy test (females of childbearing potential)

Lipid panel (triglycerides, cholesterol)

Frequency: Monthly or every 2-4 weeks during therapy.

Target: Triglycerides <200 mg/dL (ideally <150 mg/dL)

Action Threshold: Triglycerides >400 mg/dL (consider dose reduction or discontinuation); >800 mg/dL (immediate discontinuation due to pancreatitis risk).

Liver function tests (ALT, AST)

Frequency: Monthly or every 2-4 weeks during therapy.

Target: Within normal limits or stable.

Action Threshold: Persistent elevations >2-3 times upper limit of normal (ULN) may require dose reduction or discontinuation.

Special Patient Groups

🤰

Pregnancy

Absolutely contraindicated. Isotretinoin is a potent human teratogen, causing severe and life-threatening birth defects (e.g., craniofacial, cardiovascular, CNS abnormalities, intellectual disability). Females of reproductive potential must participate in the iPLEDGE REMS program and use two forms of contraception.

Trimester-Specific Risks:

First Trimester: Highest risk of severe birth defects (e.g., CNS, cardiovascular, craniofacial, thymic, parathyroid abnormalities).
Second Trimester: Continued risk of birth defects, though potentially lower than first trimester.
Third Trimester: Continued risk of birth defects, though potentially lower than first trimester.
🤱

Lactation

Contraindicated. It is unknown if isotretinoin is excreted in human milk, but due to its high lipophilicity and potential for serious adverse effects in the infant, breastfeeding is not recommended during treatment and for one month after discontinuation.

Infant Risk: High risk of serious adverse effects, including potential for teratogenicity if absorbed by the infant, and other retinoid-related toxicities.
đŸ‘ļ

Pediatric Use

Approved for severe recalcitrant nodular acne in patients 12 years of age and older. Use in younger children is not established and generally not recommended due to potential effects on bone growth (premature epiphyseal closure) and other long-term effects.

👴

Geriatric Use

Not commonly used in the geriatric population for acne. If used, caution is advised due to potential for increased susceptibility to adverse effects (e.g., bone mineral density changes, lipid abnormalities, dry skin/eyes) and presence of comorbidities.

Clinical Information

💎

  • Patients must commit to using two forms of contraception and having monthly pregnancy tests.
  • Dryness of skin, lips, and eyes is a universal side effect; advise patients on moisturizers, lip balms, and artificial tears.
  • Monitor for mood changes, including depression and suicidal ideation, and educate patients/families to report any concerns immediately.
  • Educate patients about the importance of avoiding sun exposure and certain cosmetic procedures (waxing, dermabrasion, laser) during and after treatment.
🔄

Alternative Therapies

  • Oral antibiotics (e.g., doxycycline, minocycline, azithromycin)
  • Topical retinoids (e.g., tretinoin, adapalene, tazarotene)
  • Topical antibiotics (e.g., clindamycin, erythromycin)
  • Benzoyl peroxide
  • Salicylic acid
