What's the #2 least likely non-steroidal to lead to cv risks?
Which drug has an increased risk of CHF?

But aspirin’s BENEFITS greatly exceed risks.

Ibuprofen

Naproxium sodium

Which NSAIDs for Young & healthy patients (2)

ibuprofen (3 or 4x day) or naproxium sodium (BID) – naproxium is more freq written b/c it’s easier to take

Which NSAID for patient at higher cv risk.

naproxium sodium as a first choice, unless there is any hx of CHF – then use ibuprofen

8

Which NSAID for if family hx of CVA or poorly controlled BP to put them at risk of CVA

back away from naproxium and use ibuprofen.
