The overview: every form it comes in, when a prescription is needed, which states changed their rules, and what it costs. Start here if you are not sure which question you have.

Plain-English reference pages on ivermectin for a US audience: which states allow pharmacist-dispensed or over-the-counter access, which forms exist, what the labelled uses and side effects are, and what it typically costs. Everything here is general information, sourced and dated.
Start with the overviewThe questions readers ask most
Prices, state laws and approval status are dated facts, not permanent ones. This is what has been checked, and when.
Every figure on this site is tied to a primary source and carries the date it was checked. How we source.
The reference pages
These pages cover the questions people actually ask. Each one links down to the state-by-state and product-specific detail.
ReferenceThe overview: every form it comes in, when a prescription is needed, which states changed their rules, and what it costs. Start here if you are not sure which question you have.
Protection laws are not access laws. One row per state and DC: 7 let a pharmacy supply it without your own prescription, 2 of those with nobody at the counter, 1 protection law only.
ReferenceWhich US states have passed pharmacist-dispensing or OTC laws, which forms those laws cover, and what still needs a prescription.
ReferenceWhich pharmacies and retailers stock which formulations, and why the human and animal supply chains are not the same thing.
ReferenceHow legitimate US telehealth and mail-order pharmacy routes work, and how to recognise a site that is not one.
ReferenceTypical cash prices by form, dose and pharmacy, plus how discount cards change the number.
ReferenceWhich three forms are approved for people in the US, which are approved for animals only, and a table of species, route and prescription status by form.
ReferenceWhich human forms are FDA-approved, the two tablet strengths the Orange Book lists, and why the company printed on a generic carton is not always the applicant.
Animal useEvery dosage form FDA has approved for animals: application number, species, concentration, route, and the slaughter withdrawal for food species. All are labeled for animal use only.
Animal useMeat withdrawal intervals by product, species and route on the US animal labels and regulations, why none of them states a milk withdrawal time, and why poultry has no egg interval.

This is health information, so the standard is higher. Every claim is tied to a source, every page carries the date it was last updated, and where we do not have something — a medical reviewer, for instance — the site says so instead of implying otherwise.
