Nonsteroidal Anti-inflammatory Drug (NSAID) Interactions Clinical status and serum creatinine should be closely monitored when cyclosporine is used with NSAIDs in rheumatoid arthritis patients (see WARNINGS) .
It is advisable to monitor serum creatinine and blood pressure always after an increase of the dose of nonsteroidal anti-inflammatory drugs (NSAIDs) and after initiation of new NSAID therapy during Neoral treatment.
It is advisable to monitor serum creatinine after an increase of the dose of nonsteroidal anti-inflammatory drug and after initiation of new nonsteroidal anti-inflammatory therapy during Neoral treatment.
