Dear Lynn,It's not too expensive, my insurance covers it so I get 200 tablets for $7.50. You can take up to 8 per day, as needed. I usually take 2 - 4. A life saver for me. I'm an old man now, and this darn IBS has followed me through college and dating and married life and children (who are now in college). Motofen has allowed me to lead a pretty normal life (once I found it). I was actually able to be with my kids as they grew up (a true blessing and something I doubted as I fought this disease that we all have). I'm still phobic in crowds, but I don't much like being around others, anyway. I finally figured that out and have accepted it. It's not so much an IBS thing. Lomotil, as others have warned, worked for awhile, then one day failed me and failed pretty much everytime thereafter. Immodium worked for awhile, but I had to increase the dosage over time. Motofen is perfect. And the tablet does not have a disgusting taste so it dissolves easily in my mouth (unlike the bitter taste of Codeine, from which I understand Motofen is derived). With Lomotil and Immodium, you can build up a tolerance - not so with Motofen. I know if you Google it you'll get info, but do try the Wikipedia site. Interestingly, it points out that Motofen is ONLY prescribed in the U.S. Just the opposite of most other things. The number of times I've ranted and raved to my wife about the fact the Codeine (one of the best IBS cures for me)is available much easier in Canada, then here. I really wish the government would just get out of our way. We are adults. Frankly, if I want to risk addiction to cure the curse of IBS - so be it. It's my choice. But that isn't necessary now that there's Motofen for me. I know different things work for different people, and I hope this helps you.
