Welcome to Ask The Doctor.
Thanks for asking your health related query.
Vyvnase is a drug of stimulant group. It may be used in treating ADD/ADHD. Pharmcokinetics of this drug shows that drug absorption is enhanced and its excretion is delayed by concomitant use of alkalising agents like magnesium containing antacids. So, in these conditions the level of Vyvnase may raise in blood.
It is equivalent to increased dose, that may cause more side effects like insomnia, anorexia etc. If you want to avoid these interactions, you may take Vyvnase at morning and magnesium supplement at night after about 12 hours. If you are purposefully planning to add magnesium just to enhance the euphoric effects of the drug, then it may be harmful and not advised.
Hope you understand.
I wish you a better health.
