Ivermectin †Rx
IVM blocks Wnt/β-catenin (TOPFlash ↓, β-cat nuclear ↓), collapses Δψm (JC-1 ↓, ROS ↑), activates caspases/apoptosis. Preclinical strong in renal/breast/lung/esophageal; 3–18 mg PO (Rx) safe at antiparasitic doses—monitor neuro/CYP; emerging repurposing signals.
Forms: Oral tablets (Rx, 3–12 mg)
Key Takeaway
Antiparasitic that inhibits Wnt/β-catenin signaling, disrupts mitochondrial potential/respiration, and triggers ROS-mediated apoptosis; compelling preclinical data with emerging human signals, but clinical efficacy in oncology remains to be proven.
Evidence at a glance
Strong preclinical (in vitro/in vivo); human limited to phase I/II safety/signals; oncology RCTs pending.
How it may work
Ivermectin (IVM), an antiparasitic drug, inhibits the Wnt/TCF signaling pathway, reducing β-catenin nuclear translocation and downregulating genes involved in tumor growth and metastasis. It collapses mitochondrial membrane potential, inducing mitochondrial dysfunction, oxidative damage, and ROS-mediated apoptosis via caspase activation. IVM also modulates Akt/mTOR and MAPK pathways, leading to cell cycle arrest and enhanced chemotherapy sensitivity. Preclinical studies show selective toxicity to cancer cells in renal, breast, and lung models.

Overlapping mechanisms
- Wnt ↓ / Mito ↓ / Apoptosis ↑: Avoid with other Wnt/mito/apoptotics; risk neuro/CYP overload.

Dose: as studied, not a recommendation
Ranges seen in adjunct / practice use: 3–18 mg (po) Antiparasitic: 0.15–0.2 mg/kg single dose. Repurposing exploratory: 12–18 mg/day (e.g., 6 mg TID) cycled. Preclinical HED from mouse (2–10 mg/kg) ~0.16–0.8 mg/kg (~11–56 mg for 70 kg); human pilots align at lower end., Doses up to 2.5mg/kg are called for in some protocols, but this is not a recognized safe dosage and could potentially be neurotoxic. Rx may be required. Single or weekly for parasites; daily cycled for oncology hypotheses. Take with fatty meal for absorption. Monitor neuro (dizziness, tremor); CYP3A4 substrates..
