Other combination HIV medications are available, and the choice of treatment often depends on individual patient factors and physician recommendations. Truvada, also a Gilead product, contains emtricitabine and tenofovir disoproxil fumarate, a different form of tenofovir [6].
What is the Risk of Bone and Kidney Problems with HIV Medications?
Older formulations of tenofovir, such as tenofovir disoproxil fumarate found in Truvada, were associated with a higher risk of bone density loss and kidney problems. Tenofovir alafenamide, the form used in Descovy, was developed to have a lower risk of these side effects because it is absorbed into the bloodstream less [7].
