Invega Sustenna (intramuscular injection) has a long half life range of 25 to 49 days. This is the time it takes for plasma levels to reduced by half, then in the next 25 to 49 days the plasma levels are reduced again by half and it continues.
It roughly takes around 5 to 6 half lives for a drug to be eliminated from your system to the point it is clinically no longer noticeable.
Using this calculation, as a guide, after your last dose, you could expect it to take anywhere between 150 to 300 days to be cleared from your system. Factors that cause personal variation include age, health, weight, metabolism and other medical factors.
Its been 6 and half month since my last injection and i still have side effects like tired body headache loss in concentration and pressure in my lungs can there be any type of solution to get rid of these side effects? Give me hope and God bless !!
I know you are suffering as I have too, but it will be alright. my symptoms have lessened and its been eight months and I guess it depends on how your body eliminates foreign chemicals in your body. I have hope that I will eventually be able to sleep until 7am instead of 5am and take day naps. Just hang in there!!! and don't stress.
I have been feeling really I'll since being on this drug with a lot of sleeping in and no motivation and depressed all the time
I could not be more upset that I was forced this drug. How could it last in someone's system that long? This is very irresponsible of drug manufactures and health care "professionals" to prescribe this. I literally had a stalker and the hospital said no you are schizophrenic affective instead and forced this injection on me in a psych ward. Total b.s. I HAD A STALKER.I wonder if exercise and activated charcoal would help eliminate this from my body. I have never been so fat and tired all the time and feeling so weird inside myself.
I have had it also still suffering side effects after nearly 6 months off it.
it made me really depressed and have had to be put on anti depressants which are maybe now only just starting to take effect.
paliperidone is horrible, left me where I couldn't even sit in a chair still without irritation.
glad im off it and will no longer take anti psychotics, its horrible in every way I was on 150mg injection then down to 75mg, never again
if you are reading this get off it, you, will only suffer
