What the FDA labels say

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.
Careful monitoring of lithium levels is advised in the event NSAID dosage adjustments are required.
