How is ivermectin dosing calculated by weight and what are standard regimens for common parasitic infections?

Ivermectin dosing is weight‑based, typically calculated in micrograms per kilogram and most often given as a single oral dose; common regimens for human parasitic infections fall between about 150 and...

What are reported human CSF concentrations of ivermectin in cases of neurotoxicity, and which studies measured them?

Published human reports of ivermectin-associated neurotoxicity document either the drug’s detection in central nervous system tissue or clinical syndromes consistent with CNS penetration, but the revi...

What clinical trials have tested ivermectin for COVID‑19 and what were their dosing regimens and outcomes?

A large and disparate body of clinical research tested ivermectin for COVID‑19 using regimens ranging from single low antiparasitic doses (≈150–200 μg/kg) to multi‑day high‑dose courses (including stu...

Are there preservatives, colorants, or coatings in ivermectin tablets and what purpose do they serve?

Ivermectin tablets sold for human use are documented in official product labels and drug information sources as simple, uncoated, white to yellowish‑white tablets whose inactive ingredients are colloi...

What are the safety limits and toxicities observed in humans at high or repeated ivermectin doses used in oncology trials?

High and repeated ivermectin doses explored for oncology have been tested in humans only in limited early-phase or dose‑escalation settings, showing that higher-than-approved regimens can be tolerated...

What are the pharmacokinetic thresholds for ivermectin neurotoxicity in humans and how do reported serum levels in veterinary‑product cases compare?

Ivermectin produces neurotoxicity in humans when it accumulates in the central nervous system — a process normally blocked by P‑glycoprotein — and clinical reports link toxicity to doses well above st...
