medication causing low immunoglobulins - help

[u/Strict_Bear_5122]

hi there, i’ve been diagnosed with MS for about 6 years now, (i caught it early i was 14) & im on rituximab for infusions. i started off at every 6 months & i’ve progressed to yearly & now every 18 months (yay!) i’ve noticed that this medication lowers my immunoglobulins A LOT & the last time i was infused was dec 2024 & the entire spring of 2025 i was constantly sick, it’s been 18+ months & my immunoglobulins are still low & my neurologist said it was okay for another infusion on a lower dose, but in my labs my immunoglobulins are still scarily low (for the average person i guess?) i am worried about getting constant infections again & was wondering if anyone else is experiencing this? what do you do to make sure you don’t get sick with such low levels. i know that’s what rituximab does, but i can’t help but have a little PTSD from my last infusion of being constantly sick after, honestly anything helps im just annoyed & having a lot of anxiety :(
