Funny you mention that because yesterday I read that there are people who actually need to take aspirin. https://www.washingtonpost.com/national/health-science/her-d...

Long story, short - sensitivity to aspirin is problem that can be treated with exposure to aspirin in controlled setting to reduce extreme respiratory/allergy symptoms and continued daily aspirin afterwards for maintenance.

In the article, the woman is found to be allergic to NSAIDs. Meanwhile, others are prescribed Aspirin as a blood-thinner, to prevent recurrence of stroke.[0]

Yes but the treatment involved getting aspirin under a doctor's supervision to eliminate the sensitivity, unless I misremembered that. Prior to that she get sicker and sicker until she got pneumonia, and then a doctor who happened to be familiar with the aspirin syndrome from recent work elsewhere, suggested that as a diagnosis. Under the aspirin as therapeutic her life significantly improved.

Sure but I'm getting at a different connection. In this particular study, where both groups are presumably taking antipsychotics, the probiotics might increase the effectiveness of the medicine they are already taking.
