  • * Small doses may also be used for prophylaxis.

  • ** NSAID: nonsteroidal antiinflammatory drugs were usually naproxen, sulindac, indomethacin, or celecoxib.

  • *** Prednisone, methylprednisolone, or triamcinolone usually used.

  • Since ASA is a nonprescription medication, many patients likely obtained it without a prescription.

  • †† ACE/ARB: angiotensin-converting enzyme inhibitor/angiotensin receptor blocker.
