Hi Rosebuds,
My son was also on Invega injection. After sending him to his pdoc for the nurse to administer the injection (@ $35 a whack) and never really trusting son to get the actual boxed injection (that I pick up at our CVS pharmacy) to the Pdoc’s office, I taught myself how to administer the shot myself. I used YouTube and watched several nursing instructional videos over and over and also very closely read and reread the instructions inside the injection box.
It worked out great for us, saved me the uncertainty of son completing the trip to his pdoc’s office, saved us money and time, and we did it at our convenience, not the pdoc’s nurse. It’s really not hard, I was just a little nervous the first time. It worked out fine though. One pdoc’s assistants, who my son had seen one time, actually suggested to me that I could easily do that since they did not have a nurse there.
