Truvada and Constipation: What You Need to Know
Truvada, also known as emtricitabine and tenofovir disoproxil fumarate, is a medication prescribed to treat and prevent HIV infection. It is a combination of two antiretroviral drugs that work together to prevent HIV from multiplying in the body. However, like any medication, Truvada may cause side effects in some patients. One of the common concerns of patients taking Truvada is whether it causes constipation.

How Does Truvada Work?
Truvada works by preventing HIV from multiplying in the body. The medication blocks the activity of an enzyme called reverse transcriptase, which is needed by HIV to produce new virus particles.
