The monograph says I can mix Vyvanse in water. Does that mean I can take half a capsule?

Mixing Vyvanse in water does not mean you can take half a capsule. The monograph language is about swallowing the whole dose when the capsule cannot be swallowed intact. Canadian lisdexamfetamine product information says the entire contents may be mixed with yogurt, water, or orange juice, consumed immediately, and not stored. 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 wanted to split the capsule in water because I thought the monograph had handed me a titration hack. I asked the pharmacist before I did it. They said the mix was for the whole thing, immediately, not a half glass in the fridge. I felt silly and relieved. I did not portion it. Only my almost-mistake, not a method.
