What Should I Do If I Miss a Dose of Emtricitabine?It is very important that not miss emtricitabine doses. If you do not take your medicine as scheduled, take the missed dose as soon as possible. However, if it is almost time for your next dose, skip the missed one and continue with your regular schedule. Be sure to tell your healthcare provider if you are having trouble remembering to take your HIV medications.
How Does This Medicine Work?Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI). NRTI medications work by blocking a process that the HIV virus needs in order to multiply.
HIV (human immunodeficiency virus) is the virus that causes AIDS. Like other viruses, it must use a person's own cells to reproduce. However, HIV is a little different from other viruses because it must first convert its genetic material from RNA to DNA. It is the DNA genes that allow HIV to multiply.
HIV converts its genetic material by using a special protein called the reverse transcriptase enzyme. To create DNA, this enzyme uses several different molecular building-blocks.
Emtricitabine works by tricking reverse transcriptase into thinking it is one of these molecular building-blocks. However, it is just different enough that when used to create DNA, the medication actually stops DNA from being made. Without DNA, HIV cannot multiply.
Emtricitabine is not a cure for HIV or AIDS. Although it can help stop HIV from infecting healthy cells in the body, it does not help cells that have already been infected with the virus.
