I have chronic hepatitis B, and I’m living in the US. I’m currently on TDF (generic), but I would prefer to be on TAF, due to the better safety profile on kidneys and bones. I get my kidney function checked regularly, and it has been fine every time, but I have not had my bone density tested. My insurance will unfortunately only pay for TAF for people who have chronic kidney disease or osteoporosis. I can’t afford to pay the brand-name prices. I have heard that it may be available as a generic in 2032 or 2033. The thing that I’m curious about is that I have seen some websites from other countries that seem to suggest that it’s available as a generic outside of the US. I’m not sure if that’s trustworthy information. Is it typical for other countries to have generic drugs become available before they’re available in the US?
Also, is it recommended to have my bone density tested routinely while I’m on TDF?
You should ask your doctor for a DEXA scan . To find what if you have osteoporosis or osteopenia. I have been on viread and the only problem I have is a slight osteopenia. As long as you are not underweight , very likely you will be fine with Viread .
Hi @et5656,
First, not everyone on TDF is going to have bone and kidney issues. This happens among a small portion of patients. There are patients who have been on TDF for over a decade with no issues. The important thing is continued monitoring while on TDF. It is crucial to remain under care and work with your doctor.
Yes, there is a generic version of TAF but it is not available in the US. However, Entecavir is another great option for patients. Best, Bansah1
