Rifaximin (Xifaxan) is an expensive drug used to treat traveler's diarrhea and irritable bowel syndrome with diarrhea. It is also used to prevent hepatic encephalopathy, a brain disorder that can occur due to severe liver disease. This drug is more popular than comparable drugs. There are currently no generic alternatives to Xifaxan.
I recommend to patients over age 50thst they consider doing Pap smears every three years. If they are over age 65 with no history of cervical cancer can stop having Pap smears. Women without a cervix and no previous history of cervical cancer can stop having Pap smears done following a hysterectomy. So, to answer your question, I would advise a 73 year old woman in good health with no prior history of cervical cancer and low risk factors for STD infection to stop having Pap smears.
1 If your Pap test is normal and/or you have a negative HPV test, then you do not have to have a Pap test every year. 2  For women 21-29 years old: A Pap test every three years is sufficient. Women over 30 years old should be tested for HPV if possible when they have a Pap test. 2  The combination of Pap test and HPV test results can allow less frequent screening in some women over 30.
