Ascites Not Resolving on Spironolactone and Dietary Salt Restriction — Next-Line Management

This protocol applies when ascites persists despite first-line treatment with a no-added-salt diet and spironolactone alone. When that regimen fails to meet its required clinical targets, an escalated diuretic strategy is indicated.

Previous Line — Failure Condition

First-line treatment — dietary salt restriction (no-added-salt diet) combined with spironolactone alone — did not achieve its required goals: resolution of ascites and oedema, and, once oedema had resolved, a rate of weight loss not exceeding 0.5 kg/day. Failure to reach these targets is the trigger for escalation to this protocol.

Next-Line Approach (Partial Overview)

The next step involves adding a loop diuretic alongside the ongoing spironolactone regimen, with careful biochemical and clinical monitoring throughout. The full titration schedule, dosing parameters, and monitoring requirements are contained in the complete protocol.

If this fails to resolve ascites, frusemide should be added in a dose of up to 160 mg/day, but this should be done with careful biochemical and clinical monitoring.
The initial dose of frusemide is 40 mg/day and it is generally increased every 2–3 days up to a dose not exceeding 160 mg/day.
