My son takes Vyvanse extended release as well. He metabolizes everything so quickly. An extended release for him lasts maybe 3-4 hours. He now takes 50 mg in the morning and another dose about mid afternoon that is 40 mg. If we don’t get home right after school, we can kids homework goodbye.

Increasing doesn’t usually mean it will last longer, but everyone is different. One thing to be careful of, is when some people increase medication, instead of helping, it can actually do the opposite. He was taking a med, where after they increased to see if it would last longer, he became a bit violent bc the dose was too much. But again, the painful part of trying to get it right, so you can only try to see what happens and make another adjust if it doesn’t work.
