Summary
Positives
- Xolair looks genuinely helpful for some MCAS-heavy Long COVID cases, especially when sleep, histamine reactivity, and HyperPOTS symptoms all improve together after starting it. Reddit.
Negatives
- Even positive Xolair stories are targeted, with the medication helping a specific mast-cell phenotype instead of acting like a general Long COVID fix. Reddit.
Hurdles & Side Effects
- The biggest barrier is access, because patients still describe Xolair as off-label for MCAS and difficult to obtain without the right specialist support. Reddit.
