Yes, as mentioned it sounds like classic “Crap Gap” but I haven’t experienced it myself. There is a specific FB group just for Ocrevus patients that I joined this week and it is wonderfully supportive and good info.
I did see in one article that the recommendation for dosage frequency could be pushed a bit tighter if needed. There were some questions raised if it could be influenced by the patients BMI and if bigger people needed it more frequently. I’m only 5’2″ and 140 lbs and did not notice any issues creeping back but it sounds like many do. I am watching for them and will push for a condensed cycle if it happens- you could ask?
