It's all in the dosage.
I am on Warfarin for life due to Factor 5 Leiden. Keeps my blood from clotting and almost killing me 3 times already.
Basically, it kills rodents due to the dosage. They get a massive dose, which then kills them. Humans get a therapeutic dose that keeps your blood “thinned” to a specific point.
They keep trying to get me on one of the new wonder drugs to replace Warfarin, but they seem to have some significant side effects so I'll just stick with what seems to work.
I had a heart racing issue in February 169 beats a minute from sleep. No stopping, not out of rythmn, just fast and my blood pressure stayed solidly in normal range. They got it to slow down, ran tests and found no blockages or issues on the stress test but they put a different fluid pill, lasik, Metoprolol Tartrate and Xarelto blood thinner and I hate the stuff.
I haven’t had any issues since with heart racing and have been lobbying the doctor to take me off the blood thinner and heart medication. I am having more issues with that crap than anything. I was on blood pressure meds for decades and it was under control and had little to no swelling in feet and ankles. Since they put me on the Meto and Xarelto my feet are constantly swollen and I live in the bathroom now. My quality of life has gone down significantly with these new meds.
I go back in September to the cardiologist and will once again plead my case to take me off the heart meds and blood thinner.
Forgot the sarcasm tag. There have been cases of death due to water consumption (not drowning). There’s an old expression...if it works don’t fix it.
