IT was probably amphoterycin B. That used to be the only drug to treat a systemic fungal infection. Cancer patients would get fungal pneumonia from being immunocompromised. That drug is still used occasionally, but it was awful to have to take it--very painful given intravenously before they did central lines and piclines. It just ate up your veins, but it saved a lot of lives.No clue this was many years ago, probably near 15. Fortunately my Gpa was a veteran. He bypassed the VA for most health care b/c it was sooooo obnoxious and poor, but for medications and his body parts (leg, hearing aids, glasses, dentures ect....) he would use the VA. He was 100% service connected disabled so could get his health care free when he needed to. He couldn't get all the medications he needed through them b/c you can't get meds they don't approve, he had to jump through a lot of hoops but did get the antifungal medication approved since there was no alternative. My info about it being difficult to catch and treat came from that incident and the doctors treating him at the time.
