Did the doctor specify how long she should be off the Lactulose? It seems to me that people are generally on both the Xifaxan and Lactulose.
about the Indigent Drug Program: You can find out who the manufacturer is, but your doctor's office will need to call them. They will send a form to be filled out by him, or ask that he write a letter stating that the patient needs the medication but can't afford it. They will then either send the med to the doctor's office for him to give to your mom, or they will send her a coupon to take to the pharmacy to get it free. Here's a link to more info on the program:
