[doktrin]

I read "pills" as referring to other Aspirin-class medications (OTC NSAIDs and/or pain relievers), such as Naproxen Sodium, Paracetamol and Ibuprofen.

A pill, after all, is just a transport mechanism. It's the substance of the pill that determines side effects and risk. For example, you don't often hear about multivitamins causing stomach bleeding.
