@poodledoc The only 7% saline I could find on Amazon was 24 vials of 5 ml from Naveh (Israel). The price shows up for me as $59.79 plus $7.70 for shipping. That's 5 to 10 times more expensive than what I can get from Krogers or Walgreens, especially if I use Goodrx. Won't your doctor give you a prescription if you show them the articles Terri posted? After I showed them to my GP and explained about this Mayo forum, she immediately wrote an Rx.
