@northshorepaul, it's true. Ivermectin is available as a prescription for use in humans. Here's more detail from Mayo Clinic https://www.mayoclinic.org/drugs-supplements/ivermectin-oral-route/description/drg-20064397
"Ivermectin is used to treat river blindness (onchocerciasis), intestinal infection from threadworms (strongyloidiasis), and other kinds of worm infections. Ivermectin is an anthelmintic. It works by interfering with the nerve and muscle functions of worms, by paralyzing and killing them."
This medicine is available only with your doctor's prescription.

There's a lot of information as well as misinformation circulating about ivermectin and its use as a treatment for cancer. Here's a clear and well-written article about repurposed drugs being researched for cancer.

Mayo Clinic does not currently recommend using ivermectin or other dewormers as a cancer treatment unless they are part of a research study called a clinical trial.

You may have heard about these medicines online, on social media or from friends. They also are called antiparasite medicines.

Cancer and cancer information are complex. It is common to feel anxious and overwhelmed. And with so much information out there, it can be hard to tell what is true.

Here's what Mayo Clinic experts want you to know

· There is no evidence that antiparasite medicines treat cancer in the human body. Early studies show possible benefit in lab cells or animals but not in people. Most new drugs that seem to work in lab or animal studies do not end up working or being safe in humans. So at this time, more research is needed to understand how these medicines affect people.

· Doses suggested online and on social media can be dangerous. Ivermectin and another medicine called mebendazole are approved by the Food and Drug Administration (FDA) for human use in the U.S., but only as a limited-time treatment for parasites. They are not meant to be taken daily or long-term. The antiparasite medicine fenbendazole is only approved for animals. So there is no research yet on whether taking any of these long-term is safe for people.

· Side effects are possible. These medicines can cause upset stomach, sore muscles or joints, and dizziness. You may need extra tests to check on side effects. Serious side effects — such as seizures and confusion — have sent some people to the hospital. The medicines also can affect liver test results and cause liver damage.

· These medicines may delay standard treatment. A delay in standard treatment in order to use ivermectin, dewormers or other alternative therapies can allow cancer to grow or spread. Sometimes, waiting too long to get standard treatment can lower the chances of survival.

Yes, for parasitic infections -NOT prostate cancer. How would you even know how much to take without killing yourself?
But I do think more research is necessary with these orphan drugs because you just never know, right?
