It's an atypical antipsychotic that's also approved for bipolar depression, psychiatrists like to use antipsychotics also for treatment resistant depression or very severe depression.

I recommend taking it for a while longer, side effects usually reduce after a while and there are side effects with most medication. Of course I am not qualified to give medical advice, that's just my opinion and if in doubt one should ask their practitioner.

I take Latuda, too, and had severe side effects in the beginning. More than a year later I have none. It was a life saver for me, but I know it's not like that for everyone.
