About ONFI® (clobazam)
ONFI has been shown to reduce seizures associated with Lennox-Gastaut syndrome (LGS) in people 2 years of age or older. It’s an adjunctive treatment, which means that it’s added to a treatment plan that includes other antiepileptic drugs (AEDs). Benzodiazepines, like ONFI, can cause severe drowsiness, breathing problems (respiratory depression), coma, and death when taken with opioid medicines.
In the largest clinical study to date of adults and children with LGS, adding ONFI was shown to lower the number of seizures people had each week. The study evaluated 238 participants, and the goal was to find out if adding ONFI to a person’s current treatment plan could lower his or her number of atonic, tonic, or myoclonic seizures. At all doses, treatment with ONFI reduced how often people had drop seizures each week.
In this study, the most common side effects were sleepiness or tiredness, drooling, constipation, cough, pain with urination, fever, acting aggressive, being angry or violent, difficulty sleeping, slurred speech, and problems breathing.
