Drug interactions are complex, graduated, and probabilistic. It’s generally not “drug A and drug B combined with definitely kill you” it more of “there’s a small study that shows that people who take drug A while taking drug B have a higher chance of experiencing side effect C”, or “patients taking drug A who have condition D, might experience problem E”. It’s about managing risk, making judgement calls, and accepting responsibility. There also just isn’t data for every possible drug combination or patient problem combination out there.
