Combining Lithium Carbonate and Naproxen is a major interaction and should generally be avoided without close medical supervision.
Concomitant use of naproxen with lithium can significantly increase serum lithium concentrations, leading to lithium toxicity. Patients may experience symptoms such as tremor, confusion, ataxia, and in severe cases, seizures or coma.
Mechanism: Naproxen, an NSAID, inhibits renal prostaglandin synthesis. Prostaglandins play a role in regulating renal blood flow and lithium excretion. Inhibition of prostaglandins by naproxen reduces renal lithium clearance, leading to increased lithium reabsorption and elevated serum levels.

Naproxen
Naproxen has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of naproxen, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Naproxen is a potent inhibitor of prostaglandin synthesis in vitro. Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in ani…
