So I was on Rexulti for 7 days, started at 0.5mg for three days, then 1mg for three days, then was accidentally given 2mg on the last day and it’s caused Akathisia which freaked me out and wanted off the medication, I stopped taking it 3 days ago and feel fine (akathisia is still there though) but I didn’t realise Rexulti has a half life of 91 hours, I thought it would of been around 24h and that it would be out of my system relatively quick. Given its 91 hour half life. It should be out my system in around 19 days, but will I be going into withdrawals even though I was only it for a week and at 2mg for one day? Will I still need to taper?
