What to expect
Most people tolerate NSAIDs well. Here is what is worth knowing going in, so nothing catches you by surprise.
Known interactions
Interactions involving NSAIDs's drug class that DoseIQ screens for. Each one cites where it comes from — an FDA label section or the published record — because an interaction warning you can't trace is just noise.
NSAIDs impair platelets and irritate the gut lining while the anticoagulant removes the backstop.
What to do: Occasional use is a prescriber conversation; regular use usually gets switched to something else.

NSAIDs reduce the kidney's lithium clearance; regular use can push a therapeutic level into toxicity.
What to do: Occasional single doses are a prescriber question; regular NSAID use on lithium usually gets switched. A lithium level after any change is cheap insurance.

NSAIDs constrict the kidney's inflow while ACE/ARBs relax its outflow — regular use together stresses filtration, especially with a diuretic in the mix.
What to do: Occasional NSAID use is fine for most; regular use deserves a prescriber conversation and a kidney panel.

Both irritate the GI lining by different mechanisms; ulcer risk multiplies rather than adds.
What to do: Keep NSAID use minimal during steroid courses; take GI symptoms seriously.
