Disclaimer: I am on Ocrelizumab (Ocrevus) and am not trying to freak anyone out nor put anyone off it. This is for context and needs to be kept in perspective. Nonetheless, it is something to be aware of - 1 case of a 68y old male with PPMS - and to remind your doc of. Ocrevus is very new so we need to tread carefully, better safe than sorry. https://multiple-sclerosis-research.org/2019/05/hsv-2-encephalitis-with-ocrelizumab/
