What Should I Do If I Forget a Dose of Nevirapine XR?It is important that you not miss your doses. If you do not take your nevirapine XR as scheduled, take it as soon as possible. However, if it is almost time for your next dose, skip the one you missed and continue with your regular schedule. Tell your healthcare provider if you are having trouble remembering to take your HIV medications.
How Does It Work?Nevirapine XR is a non-nucleoside reverse transcriptase inhibitor (NNRTI). Like other NNRTIs, it works by blocking a process that the HIV virus needs in order to multiply.
HIV 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 ribonucleic acid (RNA) to deoxyribonucleic acid (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 protein building-blocks.
Nevirapine XR works by attaching to the reverse transcriptase enzyme, stopping it from making DNA. Without DNA, HIV cannot multiply.
Nevirapine XR is not a cure for HIV or AIDS. It can help stop HIV from infecting healthy cells in the body, but it does not help cells that have already been infected with the virus.
