I'm with you and your approach about being supervigilant and super cautious.
I had (yes, totally past tense) a rheumatologist who prescribed tyelonol with tramadol about 30 yrs ago, ignorant of the fact that tramadol is contraindicated if patient is on cyclobenzeprine, which I was since she had prescribed the cyclo upon diagnosing very painful fibromyalgia. ONE dose that night and I hallucinated, felt like I was floating out of my body, and had night terrors. From ONE pill! When I told her about the effects of what she had prescribed, I did so in person. Paid a copay but it was so worth it to see her face become slack, and even more so when I informed her that my research specified the contraindication....needless to say, I left her practice. All she could say was "I'm so sorry.." Seriously? She should have known but instead her cluelessness impacted me horrifically. Since then, I became very invested in knowing as much as possible about any proposed medication, with no qualms or apologies for firmly turning down what is being prescribed.
Doctors that can't or won't respect that are not on my medical team.
