viread kidney news - should I be concerned?
Feb 29, 2012
I read this article about kidney problems and viread: http://www.thebody.com/content/65896/tenofovir-linked-with-risk-of-kidney-damage.html. I've been taking viread as part of atripla for a number of years now with no problems. Should I be worried?
Thank you, Matt

Hi Matt and thanks for posting.
Tenofovir (TDF) is one of the most widely prescribed and highly recommended HIV medications. It's been known for some time that the medication is sometimes associated with kidney injury. For this reason monitoring of kidney health before and during treatment has been recommended.
The new study, like previous cohort studies show a small, but increased risk of kidney injury among persons who receive TDF; this risk may be greater among certain individuals- especially those who have other kidney disease risk factors, like hypertension or diabetes, or just older people.
If you and your doctor have been monitoring your kidney health (generally I try to do this at least every 6 months in stable patients) and those reports don't show any problems, then there's no reason to be worried. On the other hand, if the lab tests show a steady decline in your kidney function (best measured by glomerular filtration rate, GFR) or elevated levels of protein in your urine, then a switch to an alternative medication might be in order.
Hope that helps. Be well, BY
