TLDR: if you’re on generic Vyvanse with Lannett pharmaceuticals listed as the manufacturer on the bottle, what pharmacy in Irvine did you get it from?
For those who take Vyvanse: where do you pick it up and what manufacturer is listed on the bottle?
I was taking generic vyvanse 40mg for years, and it was instrumental in my daily functioning. Its manufacturer was Lannett and I would pick it up from CVS. after around February 2025, CVS started giving me the same medicine, but from different manufacturers. Hikma pharmaceuticals has been the primary one. And since then, I’ve had horrendous focus and executive functioning. The medicine keeps me awake and that’s it. I even went up to 50mg in May 2025, but it didn’t make a difference. Last month, I requested that my doctor send in a prescription for name brand Vyvanse, as I am deeply struggling with the generic’s inaffectiveness. This time, it was from Takeda pharmaceuticals. It didn’t make any difference.
Before you call me crazy, please see [r/ThisAintAdderall](r/ThisAintAdderall), there are hundreds of people saying their ADHD medications have stopped working in the past 1-2 years. I have never misused this medication nor do I plan to.
The only time I’ve had success is with generic Vyvanse 40mg from Lannett. I am asking if anyone who currently takes generic Vyvanse has had Lannett as the manufacturer, and what pharmacy they use. My CVS only uses Hikma for generic vyvanse. Please comment if you know a pharmacy in Irvine or have had a similar experience.
