Connie,
Yes, I consider myself very lucky to have gone through that without any serious complications. It's no wonder that drugs are frequently so deadly in the hands of doctors, though. When I went to the ER that day, I was on the backside of a major hypertension event, due to a drug interaction caused by rasagaline, (which I had been taking, due to a misdiagnosis of Parkinson's Disease, (at least, I
think it was a misdiagnosis). In fact, I had gone to that same ER, exactly one week earlier, because of the blood pressure issues. When they hooked me up to the monitors, my blood pressure was 225/127.
I had stopped taking the rasagaline, the day before I went to the ER, (which was 8 days before the bleeding began), when I discovered that it interacted with 625 common drugs, that my neurologist failed to mention.

The drug that I attributed the interaction to, was a common antihistamine, taken for hay fever. The reason why I went to the ER on the second day, (after I discovered that I was having hypertensive issues), was because blood pressure spikes, caused by drug or food interactions with rasagaline, typically peak on the second day of the interaction event. (The food interactions that I refer to here, involve foods that are high in tyramine, such as dried foods, aged cheese, etc.) Unfortunately, though, it takes at least 5 or 6 weeks for the body to get rid of roughly half the residual rasagline - the body has to use it up, it can't just dump it. No one knows how long it would take to get rid of all of it.

Rasagaline is an extremely persistent drug - it takes a long time to build up a working supply of it, and then if you stop taking it, it does not have a true half-life, so it takes virtually forever to get rid of it. I went through all of that background information, when I was checked into the ER, so it was surely in my records.
Anyway, even though I carefully explained the risks of drug interactions, (due to the residual rasagaline in my system), to most of the doctors treating me, I got the impression that not one of them believed me, and they prescribed several drugs that were contraindicated, that went into the IVs, (I found out after the fact, mostly from nurses). I'm convinced that besides not actually understanding how monoamine oxidase inhibitors actually work, and therefore not being able to comprehend the risks that they impose, most doctors believe that in a hospital setting, they don't have to worry about drug interactions, because they consider them to be a rare event, and they have the tools to intervene, if necessary. Also, they may have just incorrectly assumed that after one week, the risk of an interaction was gone, (they probably didn't believe me, when I told them how long the risk would last). I have no doubt that that mistake was the reason why they had to give me drugs to lower my blood pressure, every day, while I was there. As soon as I got home, my blood pressure returned to normal, (because I didn't take anything that could cause an interaction).
I really believe that most doctors perceive most drugs to be much safer than they actually are. They prescribe them to so many patients, without any major problems, that they become comfortable with them, and if something does happen, they rationalize it, (in their minds), as a rare event, or blame it on something else, (such as patient error).
