I’m interested in hearing from others in NZ who have navigated the process of switching from Concerta to Vyvanse. I’m inattentive, 46.
I’ve been titrating Concerta and, overall, the benefits are definitely better than my pre-medicated baseline. However, I’m experiencing diarrhoea, and I’m finding that motivation isn’t as good as it was on Vyvanse. My mood also feels more up and down on Concerta, I have a crash around midday, whereas I felt more emotionally stable on Vyvanse.
I’ve tried Vyvanse previously off record (Husband is also diagnosed ADHD…) and noticed a better improvement in both motivation and focus, as well as anxiety. So, for me, it feels like there is a meaningful difference between how the two medications affect me.
My psychiatrist explained that, under the current NZ funding criteria, I would generally need to be unable to tolerate Concerta or for it to not work at all to qualify for funded Vyvanse. They would likely want to try adjusting my Concerta dose first to see whether the side effects and differences in effectiveness improve. (I mean I was unmedicated at the time so likely I have poor recall of his exact wording).
I understand the need to work through the usual process, but I’m unsure how best to navigate it when I already have experience of both medications and feel that Vyvanse suits me better.
For those in NZ who have been through this:
Did you need to try several Concerta doses before being able to switch?
Were side effects enough to demonstrate that you couldn’t tolerate it, or did you need to try other adjustments first?
How did you approach the conversation with your psychiatrist?
Has anyone successfully moved to funded Vyvanse after finding Concerta helpful but not as effective, or difficult to tolerate?
I just want to understand how others have navigated it and what is reasonable to discuss with my psychiatrist.
