If you do not use an Elixir in a Ruin of Thandar encounter, is it still available later?
A single reply describes this; no official ruling is given.

Usually no. An Elixir is a one-encounter reward: it stays with you until you use it or win that encounter, then goes back in the box. If you lose the encounter, you get it back for your retry.
