What the FDA labels say
From the Lithium (Lithium Carbonate) label · effective 2026-06-04
• Diuretics, NSAID, renin-angiotensin system antagonists, or metronidazole may increase lithium serum concentrations.
Non-Steroidal Anti-inflammatory Drugs (NSAID) Clinical Impact: NSAID decrease renal blood flow, resulting in decreased renal clearance and increased serum lithium concentrations.
From the Nabumetone label · effective 2026-01-01
Lithium: NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance.
The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%.
Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity.
