DEERFIELD, Ill.–(BUSINESS WIRE)–Lundbeck announced today that ONFI Tablets are now available for prescribing in the United States. The FDA recently approved ONFI for adjunctive treatment of seizures associated with Lennox-Gastaut syndrome (LGS) in patients two years and older.1 ONFI is an oral anti-epileptic drug (AED) of the benzodiazepine class, and is a 1,5 benzodiazepine.1 ONFI (pronounced “ON-fē”) is a federally controlled schedule four substance (C-IV).

“In clinical trials, ONFI was shown to be an effective add-on therapy for seizures associated with LGS in adults and children two years and older. ONFI’s availability is important news for patients and their caregivers to discuss with physicians.”

“The availability of ONFI is the result of extensive efforts over many years by our team here at Lundbeck and the medical community,” said Staffan Schüberg, president of Lundbeck in the U.S. “We have been inspired by the courage of patients and families impacted by LGS, and their strength never to give up on the goal of additional seizure management. Recognizing the need for additional treatment options due to the intractable nature of this challenging seizure disorder, we are very pleased to make ONFI available in the U.S.”

LGS is a rare and severe form of epilepsy that is typically diagnosed in childhood and often persists into adulthood.2,3 LGS is associated with multiple types of seizures with periods of frequent seizures, and daily seizures are common.4 Some of these seizures, including atonic, tonic and myoclonic seizures, may cause falls, or “drop seizures” (also referred to as “drop attacks”), which may result in injury. 2

“LGS can take a toll on even the strongest families due to the frequency and severity of seizures, including drop seizures.” said Yu-Tze Ng, director of epilepsy at the University of Oklahoma Medical School and lead investigator of clinical trials supporting the approval of ONFI. “In clinical trials, ONFI was shown to be an effective add-on therapy for seizures associated with LGS in adults and children two years and older. ONFI’s availability is important news for patients and their caregivers to discuss with physicians.”

Support to Help Patients Get Access to ONFI

ONFI is available to patients at retail pharmacies with a prescription from a healthcare professional. Additionally, if a healthcare professional elects, Lundbeck has created the ONFI Support Center that will assist healthcare professionals and patients with benefits investigation, prior authorizations and is responsible for Lundbeck’s patient assistance program. Where permissible, a sample voucher program will provide a free ONFI trial to any eligible patient. Also, co-pay assistance is being made available to those who are eligible. The ONFI Support Center is available by calling 855-345-6634.

Important Safety Information

  • ONFI can make you sleepy or dizzy and can slow your thinking and make you clumsy which may get better over time. Do not drive, operate heavy machinery, or other dangerous activities until you know how ONFI affects you. Do not drink alcohol or take other drugs that may make you sleepy or dizzy while taking ONFI without first talking to your healthcare provider as your sleepiness or dizziness may get much worse.
  • ONFI can cause withdrawal symptoms. Do not suddenly stop taking ONFI without first talking to a healthcare provider. Stopping ONFI suddenly can cause seizures that will not stop (status epilepticus), hearing or seeing things that are not there (hallucinations), shaking, nervousness, and stomach and muscle cramps.
  • ONFI can be abused and cause dependence. Physical dependence is not the same as drug addiction. Talk to your healthcare provider about the differences. ONFI is a federally controlled substance (CIV) because it can be abused or lead to dependence.
  • Like other antiepileptic drugs, ONFI may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. Call your healthcare provider right away if you have any symptoms, especially sudden changes in mood, behaviors, thoughts, or feelings, and especially if they are new, worse, or worry you.
  • Tell your healthcare provider about all of your medical conditions including liver or kidney problems, lung problems (respiratory disease), depression, mood problems, or suicidal thoughts or behavior.
  • If you are pregnant or plan to become pregnant, ONFI may harm your unborn baby. You and your healthcare provider will have to decide if you should take ONFI while you are pregnant.
  • ONFI can pass into breast milk. You and your healthcare provider should decide if you should take ONFI or breast feed. You should not do both.
  • Tell your healthcare provider about all the medicines you take including prescription and nonprescription medicines, vitamins and herbal supplements as taking ONFI with certain other medicines can cause side effects or affect how well they work. ONFI may make your birth control medicine less effective. Talk to your healthcare provider about the best method to use.
  • The most common side effects seen in ONFI patients include: sleepiness; drooling; constipation; cough; pain with urination; fever; acting aggressive, being angry or violent; difficulty sleeping; slurred speech; tiredness; and problems with breathing.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit, or call 1-800-FDA-1088.
