Fenbendazole and Ivermectin for prostate cancer : what is the evidence ?

There is a significant social media promotion of these two drug combination- fenbendazole and ivermectin – for treatment of prostate cancer.

They are relatively cheap and so cost is not a major hindrance.

Are they both any good for routine clinical use ?

The short answer is NO.

Both Ivermectin and Fenbendazole are drugs currently licensed for treatment of human and / or animal infections.

There is lot of pre-clinical laboratory evidence to indicate anti-cancer activity regarding these two drugs. But that does not mean they can be safely used clinically. Good clinical trials are needed before they can be used clinically .

Remember both drugs can have significant side effects. ( Ivermectin . Fenbendazole ).

For instance, these drugs can cause liver damage. They can cause nausea, stomach pain, muscle pain, joint pain and in worse cases cause mental changes.

Advanced cancer patients are desperate to try anything. It’s human nature to fight . But that doesn’t mean trying “unproven treatments” are a good idea. This is because the side effects of the drugs can make cancer patients life even more miserable.

Both the drugs – Ivermectin and Fenbendazole- can also interfere with other cancer treatments.

Scientifically, we cannot 100% rule out that a derivative of Ivermectin or Fenbendazole might be repurposed for cancer treatment in future.

But it is NOT a good idea to use Ivermectin or Fenbendazole as an anti-cancer treatment in routine clinical practice NOW.

Be careful. Discuss your concerns with your doctor.

Be aware of scams.

Also be very careful about friends, family members and well wishers – with good intentions – but unknowingly passing misleading information to you !

Ivermectin for COVID-19 : what’s the evidence?

Ivermectin tablets are used in human beings to treat a disease called onchocerciasis (river blindness) and various infections caused by parasites. It is also sometimes used for “difficult-to-treat’ scabies. Ivermectin is also used as skin cream for certain skin conditions.

Ivermectin tablets are used in veterinary medicine to treat various parasitic infections.

There is genuine scientific interest in evaluating Ivermectin as a COVID treatment. But the evidence is not good enough for widespread use outside the clinical trials.

Unfortunately, there is widespread promotion of ivermectin in certain countries and there is a significant risk that people may be harmed by this promotion. (Side effects: Ivermectin data sheet).

That’s why the FDA and European regulators have advised against the use of Ivermectin outside clinical trials.
