Hi, Toolost. Well, that's good news that the scan showed no lesions! The TIPS should work indefinitely. Someone with more experience with that can address that issue. As for the MiraLax, I take it. In fact, the hepatologist prescribed it prior to it becoming available OTC. It's a fiber laxative, very gentle. Is your husband also taking Lactulose? If not, then the MiraLax should be okay for him. It IS important to make the hepatologist aware of everything he's taking, though, even OTC vitamins and supplements.
It's a shame that your husband doesn't want to take the antidepressants, though they usually all have side effects that can be unpleasant (weight gain and dry mouth are two common ones.) However, I'm glad to hear that he isn't drinking alcohol!
Thanks for keeping us updated! Don't forget to be good to yourself!
