Correct answer: B — Desmopressin (DDAVP)

Desmopressin (DDAVP, oral melt preparation preferred) provides rapid short-term dryness and is ideal for situations requiring predictable dry nights (school camps, sleepovers). Fluid restriction in the evening is important. Relapse is common on cessation. It can be used as first-line or adjunct to alarm therapy. Hyponatraemia is a rare risk if fluid restriction is not observed.
