May 2026 in “Zenodo (CERN European Organization for Nuclear Research)” Topical finasteride effectively treats hair loss with fewer side effects than the oral form.
February 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This paper proposes a novel theory that certain symptoms of Post-Finasteride Syndrome may be caused by an overgrowth of hydrogen sulphide-producing bacteria in the small intestine, which acts as a mitochondrial toxin, with implications for treatment targeting the gut microbiome.
February 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This theoretical paper proposes that a subset of Post-Finasteride Syndrome cases may be driven by a gut-derived toxic process involving hydrogen sulphide-producing bacteria, suggesting that the small intestinal microbiome could be a potential target for treating this condition.
December 2025 in “Zenodo (CERN European Organization for Nuclear Research)” This policy brief highlights that post-drug syndromes remain under-recognized in pharmacovigilance, leading to inadequate risk assessments and patient care. It identifies systemic failures in current frameworks and recommends actions to improve long-term drug safety monitoring and education, affecting public health outcomes significantly.
