Following recent warnings from the FDA about the potential side effects of Onfi, an anti-seizure drug, the lawyers at Saiontz & Kirk, P.A. are now reviewing the potential for Stevens-Johnson Syndrome (SJS) lawsuits and Toxic Epidermal Necrolysis (TEN) lawsuits on behalf of former users of the medication who have suffered these serious and potentially life-threatening skin reactions.

In a statement issued December 3, the FDA warned about the potential risk of Onfi skin reactions, indicating that cases of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis have been reported worldwide, including a large number of children taking the medication. SJS and TENS are serious reactions that may be caused by Onfi, resulting in:

  • Rash, blisters or red spots on the skin
  • Blisters in the mouth, eyes, ears, nose or genital area
  • Eyelid swelling
  • Fever or flu-like symptoms.

Onfi Stevens-Johnson Syndrome (SJS) Side Effects

Onfi (clobazam) is an antiseizure drug by Lundback approved for the treatment of patients with Lennox-Gastaut Syndrome (LGS), a severe form of epilepsy. It was approved by the FDA in October 2011.

More than 30 cases of SJS have evidently been reported worldwide, including at least five children in the United States. At least one death and one case of blindness have also been reported.

The Onfi Stevens-Johnson Syndrome risk appears to be highest during the first eight weeks of treatment, or after a consumer has stopped and restarted the medication.

It appears that Lundback may have failed to adequately research the potential side effects of Onfi or warn about the risk of users developing severe skin reactions. The FDA is now requiring new label warnings for the medication, but individuals previously diagnosed with Stevens-Johnson Syndrome or Toxic Epidermal Necrolysis may be entitled to financial compensation through an Onfi lawsuit as a result of the drug maker’s decision to place their desire for profits before consumer safety.
