Drug News

The American Academy of Dermatology and AAD Association recently released their updated position statement on isotretinoin, which continues to support physicianmonitored use of the drug for the treatment of severe acne. The AAD’s stance affirms patient safety is the primary concern and its commitment to the safe and responsible use of isotretinoin, generally considered by dermatologists to be the most effective treatment for severe recalcitrant nodular acne. This most recent amendment dated November 13, 2010 includes the following revisions:

  • The AAD advocates compliance with the manufacturer-sponsored and US FDAapproved risk management program for prescribing isotretinoin (iPLEDGE). The Association opposes on-line Internet dispensing, sharing, or use without physician supervision, because these activities do not provide for sufficient patient education about isotretinoin risks and do not require participation in the iPLEDGE* program.
  • A correlation between isotretinoin use and depression/anxiety symptoms has been suggested, but an evidence-based causal relationship has not been established. Other studies give evidence that treatment of acne with isotretinoin was accompanied by improvement of both depressive and anxiety symptoms, as well as improved quality of life of patients with acne.
  • Current evidence is insufficient to prove either an association or a causal relationship between isotretinoin use and inflammatory bowel disease (IBD) in the general population. While some recent studies have suggested such a relationship, further studies are required to conclusively determine if an association or causal relationship exists and/or whether IBD risk may be linked to the presence of severe acne itself.

The position statement concludes that the prescription of isotretinoin for severe nodular acne continues to be appropriate as long as prescribing physicians are aware of the risks and concerns related to isotretinoin use and that their patients are monitored for any signs of IBD and psychiatric disturbances. Education by treating physicians to encourage patient vigilance in recognizing and reporting signs of IBD and depressive symptoms is also endorsed.
