What to do

Treat as a life-threatening emergency and get to a veterinarian immediately, even from a small amount.

Toxic component and mechanism

The toxic component in Desert Azalea is cardiac glycosides.

What makes this plant different

Despite 'Azalea' in its common name, Desert Azalea (Adenium obesum) is unrelated to true Rhododendron/Azalea species — it belongs to the Apocynaceae family alongside Oleander and shares that family's dangerous cardiac glycoside mechanism, not the grayanotoxins of true azaleas.
