Hi guys hope you are all doing well,sorry to be a pain but I'm a lil lost/confused,my lovely pop's is not at his best just now his legs do not want to do what they should he is very slowly shuffling around,totally drained weak,quite shaky with his hands and feeling very down which is understandable. Although pop's has been like this before recently on our visit to his consultant after reading this site trying to understand/educate myself to try to help my dad the best we can,I mentioned Rifaxamin as so many on here has it with lactalose and it has never been mentioned to us before,I also think he most certainly should have had this at least prior to this episode he is having now. Consultant prescribed my pop's rifaxamin with no hesitation said he didn't need it now but for us to give it when needed which is great I think. My concern is when do I give him this as nothing has been explained in detail to us about HE,only thing mentioned was toxins can go to the brain,lactalose can help get rid of toxins,basically that's it how bad does pop's have to be before I give him this and has anyone experienced any bad side effects with it? Sorry again for this but honestly I feel since there is nothing they can surprosedly do for him they choose to leave us to figure everything out ourselves which would be fine if I were a doctor. All I want is to keep my dad safe and as well as can be,he is staying home with his family we will care for him till his last breath just hate having to figure stuff out medication wise surly it's not to much to ask but I will fight for my dad whatever he is entitled to,so if anyone can give me some insight about when to take these tabs or anything else plz do let me know sorrry for going on & on.
