I would like to respond to this in a few ways. First, I don't think that eating a banana a day is a good enough way to keep your potassium level within the proper range. Secondly, if you are told to take potassium because you are taking lasix, I would most certainly take the potassium, and not play games. Yes, the K-Dur are huge. I take 3 a day. What I do is have them roll to the back of my throat long ways, so they are not going down point first. They basically roll down when you take a large gulp of water. I take one, and space it by a few minutes or so. There is also liquid potassium that tastes nasty, but you can take it with OJ. The mosted important point I want to make, is that you need to keep your potassium within the normal range. I had a very good friend who went into cardiac arrest because her potassium was too low. So, I would rather gag a little than die from low potassium. When forst starting Lasix, your potassium level should be checked within the first month or two so you can adjust accordingly. They usually say the for each 20 mg of Lasix, the average person requires 20meq of K-Dur. However, I take 40 mg of lasix, and need 60-80 meq. of K-Dur. That's why it is important to have a potassium level done early on.
