For Lennox-Gastaut Syndrome "A caregiver review. Started our adult daughter on Onfi for LGS (Lennox-Gastaut syndrome). In my opinion, there is an interaction between ONFI and Psych medication. It appears that the interaction amplifies many of the Onfi side effects (physical and behavior). Since ONFI was the only new variable in her medication regime what we observed was more than mere coincidence. Please carefully read the FDA listed side effects of the medication. Onfi is the Neurology team’s new and favorite drug. They can’t or won’t acknowledge that the list side effects are from the result of Onfi. Neurology will go out of their way to blame everything else under the sun."

For Lennox-Gastaut Syndrome "Justin became very shaky, weak, lost stability that he has not gained back. He went into massive seizures when on the drug. After two hospitalizations, we took him off. It has been over a year and he continues to have difficulty with standing up in the mornings and walking all the time."

For Lennox-Gastaut Syndrome "This has been the best medicine for Lennox-Gastaut Syndrome in our sons 11 years. It was tough going for about 6 months of severe highs and lows of crying to laughing hysterically. But getting through that has been amazing. He's more vocal, his pupils are not staying dilated and he seems to understand more. I would tell any parent looking for help to please give this medicine a try."

For Lennox-Gastaut Syndrome "It has an opiod effect. I forget words I've know all my life. I am more fatigued. My doctor prescribed it for me "because". I haven't noticed any effect. Coming off the drug, my foot and upper leg get shaky. It is also a very expensive drug."

"I was prescribed Onfi after a grand mal and a series of clonic tonic seizures, where I ended up hospitalized. I woke up feeling very loopy and euphoric. I was given a 10 mg dose once per day and my seizures stopped. However, once I was released, I realized my mood was unmanageable. I was crying and laughing uncontrollably. I could not get a handle on my emotions from one minute to the next. I had to stop taking it immediately! I switched to another medication and the side effects completely left."

For Lennox-Gastaut Syndrome "I've been on Onfi for 6 months and no change, I'm having more warnings and massive seizures so it is not a good drug for epilepsy. The side effects are sedation and fatigue I'm on 5mg"
