Independently, both aspirin and SSRI's (e.g., paxil) can cause gastrointestinal (GI) bleeding or ulceration. If taken together, I'm wondering if the chance of GI bleeding is increased.
In the case of aspirin, the risk of GI bleeding is dose dependant. At higher daily doses (i.e., greater than 300 mgs) there is a 2.4% chance of bleeding and some bleeding in 4% of the cases.
This has me concerned as I'm doing an ECA stack and I also take an SSRI (i.e., Lexipro). So far, I don't see black stools which are indicative of bleeding but I also read that bleeding can be asymptomatic. I did some research on this online but I didn't find too much on this. Does anyone have any info on this?
