Across 5 studies, 2 reported beneficial effects of N-acetyl cysteine on platelet recovery, with moderate to large effect sizes in specific clinical populations, while 3 studies showed neutral findings. The most robust evidence comes from an RCT in critically ill adults using linezolid, where NAC accelerated platelet recovery (adjusted HR 3.88, p=0.011). Effects were observed in clinical populations with thrombocytopenia, with a median study duration of 365 days, though dose data is limited.
- Studied populations: critically ill adults receiving linezolid, patients with myeloid malignancies undergoing HSCT, patients with immune thrombocytopenia, and patients with thrombotic thrombocytopenic purpura
Caveats: Evidence base is small (only 5 studies) — conclusions should be considered preliminary. Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests. Results are derived from clinical populations with specific underlying conditions, limiting generalizability to healthy individuals.
