Iloperidone for Psychosis "I was put on Fanapt for my bipolar a little over a year ago. I also take other medicines, but this one really did the trick for me and got me on track. I do struggle with the drowsiness and take it early in the evening in order to get up the next morning, but it is worth it to me."

Iloperidone for Psychosis "I've been on this for a month. The symptoms I was put on this medicine to control are under control. It's worked great for that. The problem lies with the side effects. I'm sleepy constantly. I went from sleeping less than 4 hours a night to sleeping more than 12 hours a day. I'm exhausted. I've put on weight, and I have a stuffy nose, head cold symptoms all the time. If I miss a dose, the cold-like symptoms let up, but when I take the next dose, it's back in full force. I have been 'sick' for the last month. No medicine that I've been put on for the 'cold/allergies' helps. It has to be the Fanapt causing it. I'm miserable. I stopped taking it 2 days ago, and the cold just magically went away. Imagine that!"

Iloperidone for Psychosis "I was put on this a few days ago. It does seem to level out my mood, and it seems to make me 'spin out' a lot less. Sleeping better after stressful situations, and am bouncing back from emotional setbacks much better. Only problem so far is I am unable to ejaculate. Hoping they find something that will allow me a sex life, though. I am dizzy and groggy on it too. But I will definitely use this if no other treatment gives me the peace that Fanapt does."

For Bipolar Disorder "I have suffered with BP I my entire life but wasn’t diagnosed until 5 years ago. Until I found Fanapt, I had awful experiences with other medications. I took a med that lowered my WBC to a deficit that was dangerous and switched. I had severe weight gain (35 lbs) and grogginess with another. I tried Vraylar and I began having twitching in my face and in my hands. This brought me to a breaking point. Most of the meds had some positive effects but were so overpowered by the enormous life-changing side effects. After this, I changed to Rexulti, but the twitching did not stop. I feared it was irreversible and would be with me for the rest of my life. About three weeks after switching to Fanapt, the twitching ceased! My doc said he has seen this with other patients as well. My weight returned to normal and I began to have a feeling I had never experienced before; calmness. I am so grateful for this medicine. It has truly changed my life."
