View Full Version : Does Niacine (Vitamin B3) wear off Vyvanse?

Hi All,

I am on Vyvanse 50 mg. Today after 2 hour taking Vyvanse at 9 AM, I've used 250 mg Niacine for the first time hoping to solve my cold hand issue on med. And than I lost Vyvanse at 1 PM, completely wiped out from my system and I am back to my ADD. Normally it should continue till 8 PM.

I googled around but could not find anything related other than people trying to flush drugs from their system. While this ringed some bells, i couldn't trust those.

Did someone ever have same experience?

I have no negative interactions with any vitamins – high or low dosed.
