If I throw up an hour after Vyvanse, do I redose?

Vomiting an hour after lisdexamfetamine is not an automatic reason to take a second full capsule. A second long-acting dose can be too much if a substantial amount was already absorbed. Whether anything was kept down is not something a forum can judge from a clock time alone. If the change is persistent, distressing, or affecting daily functioning, bring a brief timeline to the prescribing clinician rather than changing the dose independently.

I threw up after a capsule once and my first thought was to take another so the day would not be wasted. I called the pharmacy instead and felt like I was overreacting. They asked questions I could not answer cleanly, like how much I had kept down. I did not redose. I was useless that afternoon and annoyed about it. I would not tell anyone to copy my stomach. It was one ugly morning.

I am the person who wants a flowchart. Vomit plus clock time is not a flowchart I could find that felt safe. I put the remaining capsules away so I would not bargain with myself. I messaged the clinic nurse line. Waiting was miserable. I still do not know how much was absorbed. This is not a how-to. It is me admitting I wanted to redose and then did not.
