I believe the makers of Latuda extended their patent to 2019. I would recommend calling the manufacturer directly. Latuda does have a discount program, but I believe that it needs to be a covered medication. You can also call Latuda's customer service, let them know that your insurance plan excludes their medicine, and they may be able to get you on a discount program. The medicine still may be expensive, but it's worth looking into it. I will admit that I'm biased because Latuda is the only medicine that I have responded well to, although it took a while to kick in.
