Life-Threatening Skin Reaction Linked to Clobazam

Destiny Baker3 years ago

The U.S. Food and Drug Administration is requiring a label update for all forms of the anti-seizure drug clobazam following reports of severe skin reactions in patients.

Clobazam Linked to Severe Skin Reactions

  • According to the MedPage Today, 20 patients worldwide have developed Steven-Johnson syndrome or toxic epidermal necrolysis after taking the drug.
  • The reactions have resulted in one patient going blind and all 20 patients being hospitalized including five children in the U.S.
  • Clobazam (brand names Frisium, Urbanol and Onfi) is used in the treatment of seizures associated with Lennox-Gastaut syndrome and is approved for use in adults and children as young as two.
  • Labels will not be required to warn of the life-threatening skin reactions and advise that treatment with clobazam be stopped at the first sign of skin rash.
  • Patients taking clobazam are urged to seek immediate medical attention should they notice hives, blisters or skin peeling.

About Steven-Johnson Syndrome

  • Steven-Johnson syndrome is a potentially fatal condition that occurs when the skin and mucous membranes react severely to infection or medication.
  • The condition is marked by flu-like symptoms followed by a painful red or purple rash. The rash then begins to spread and blister resulting in the top layer of skin dying and shedding.
  • Death can occur in up to 15 percent of untreated cases.
