What are the uses of this medicine?

• prescribed by healthcare providers that are registered in the iPLEDGE Program.

Limitations of use:

How does this medicine work?

• Isotretinoin is a retinoid, which when administered at the recommended dosage, inhibits sebaceous gland function and keratinization.
• The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with isotretinoin capsules and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.
• The exact mechanism of action of isotretinoin in the treatment of severe recalcitrant nodular acne is unknown.
