Nevirapine XR Dosage
Before starting treatment with nevirapine XR, you will have to take the short-acting version of this drug for at least 14 days. If you do not develop a skin rash during this time, your healthcare provider may switch you to nevirapine XR 400 mg once daily. Do not miss any doses, as doing so may cause the HIV virus to become resistant to this medication.
An Introduction to Your Dosage of Nevirapine XRFor adults, there is only one standard dose for nevirapine XR (Viramune® XR™), regardless of your age or weight. For children, the recommended dosage varies depending on the child’s height and weight. As always, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Nevirapine XR Dosing for HIV/AIDS in AdultsTo help minimize the risk for skin rashes, it is necessary to start with 14 days of regular, short-acting nevirapine (Viramune®) at a dosage of 200 mg once daily (this is called the "lead-in period"). If you have not had a rash after taking this medicine for 14 days, your healthcare provider can switch you to nevirapine XR 400 mg once daily.
If you are already on short-acting nevirapine, you may switch to nevirapine XR without the 14-day lead-in period.
If you stop taking nevirapine XR for seven days or more, you may restart the drug only after another 14-day lead-in period.
Nevirapine XR should be used in combination with other HIV medications as part of an HIV "cocktail" (this is known as highly active antiretroviral therapy, or HAART). If you are undergoing dialysis, you may need an extra dose of short-acting nevirapine after each dialysis session.
