Invega sustenna

Continuing the discussion from Invega Sustenna injection, my son, paranoid schizophrenic:

cbbrown for how long did you try sustenna 234mg injection along with latuda and oral invega.
When did the doctor decide to add latuda.
My son has been on risperdal for about 15 months in total out of which first 5 months were risperdal mtab. Next 8 months on risperdal consta and risperdal mtab. Now for the last 6 weeks he started invega sustenna (which is again another form of risperdal) plus oral risperdal mtab. I still do not see much of an improvement. I am really praying that it starts helping. Otherwise may be risperdal is not the med for him.

I tried it for about 5 months, I was on latuda before taking invega.
