I just saw the warning about nevirapine from the FDA. http://www.thebody.com/fda/nvp_advisory.html
Can you explain it to me?Women with a CD4 count over 250 should avoid starting a regimen with nevirapine (Viramune), right? If they are on currently and doing ok it's ok, right?
Response from Dr. Young
Thanks for your post.
A small percentage of persons who start on nevirapine develop a very severe allergic reaction that result in liver injury (and very rarely death). The allergic reaction is tied to immune function, so paradoxically, persons with higher initial CD4 counts (such as women with CD4s greater than 250) are at higher risk-- hence the warning.
For persons who are currently taking nevirapine and are doing "ok", there is little or no additional risk and there is no need to discontinue the medication. BY
