Hello Judith, My husband took it also. And it worked great for him too. It's actually an antibiotic. With the suppressed immune system patients get infections frequently......at least my husband did. He also acquired that highly resistant Staph infection MRSI by visiting the ER and being hospitalized so much. So between the infections and high ammonia levels they tend to have frequent bouts of encephalopathy. So if the patient takes both Lactulose and Rifaximin it really helps them not have the encephalopathy so often.
And Cary is right it is very expensive. So I do hope that your husband is getting it free.
Both of you have a great day..........
When the going gets tough....the tough get going! Don't always know where I going but I get there anyways.
