I have been on Ritalin since I was 12 and on Brintellix since August. According to Wikipedia Brintellix increases the glutamate level in the brain while Ritalin does seem to do the same. However the only known interaction between the two has something to do with Ritalin delaying the metabolism of Brintellix. So is this combination safe? I think that my doctor wouldn't have allowed me to still take the Ritalin if it would be exitotoxic and therefore neurotoxic
