A friend had a similar experience. He was getting faint and very tired quite often. Unbeknownst to him, TWO doctors at the same facility prescribed BP medication for him, so he was effectively taking a double dose.
Now, what’s puzzling is that pharmacy software has been around for decades and designed to prevent this sort of thing. How did it miss it? AND, my friend has had a lifelong history of LOW blood pressure. I can’t understand why he was prescribed medication to reduce his BP, unless they did it routinely based on his age. ??
