Drug interactions and medication reconciliation — branching viva
A branching viva following one child from a new prescription through anticipating a cytochrome P450-mediated interaction, predicting the direction and timing of inhibition and induction, choosing among avoid-substitute-adjust-monitor, and reconciling every medicine at admission, transfer, and discharge.

Branching cross-examination
This is a MedVellum formative viva. It is not an official RACP, MRCPCH, ABP, ACGME or RCPSC station, mark scheme, duration or pass standard. Release each update only after the candidate names the interacting pair, the shared enzyme, the direction and timing of the effect, and the planned action. [1] [7]
Candidate brief
You are the general paediatric registrar caring for a 14-year-old girl who is four years post-liver-transplant. Speak as you would on a ward round. Anticipate interactions before you prescribe, name the enzyme and the direction, and reconcile every medicine at every transition. Each escalation branch leads to the next update. [7]
