Frequently Asked Questions

Which is better Fenbendazole or Ivermectin?

+

It depends on the type of parasite. Fenbendazole is better for intestinal worms like roundworms and whipworms. Ivermectin works well against external parasites like lice, mites, and some internal worms. Each drug has unique strengths, so the better option varies based on the specific infection and species needing treatment.

Which parasites does Ivermectin not treat?

+

Ivermectin doesn't treat tapeworms, flukes, or protozoa like Giardia. It\'s ineffective against parasites that don't have the nerve and muscle targets Ivermectin affects. For these, drugs like fenbendazole, praziquantel, or metronidazole are often required. Always consult a healthcare provider or vet for proper diagnosis and treatment choice.

What does Ivermectin do to your brain?

+

In rare cases, high doses of Ivermectin may cross the blood-brain barrier and affect the nervous system. This can cause dizziness, confusion, tremors, or even seizures. Normally, the brain is protected from such effects, but overdosing or genetic conditions like MDR1 mutations may increase the risk.

Does Ivermectin get rid of face mites?

+

Yes, Ivermectin is used to treat face mites, especially Demodex mites linked to rosacea or skin irritation. It can be taken orally or applied topically, depending on severity. Many people see reduced redness, itching, and inflammation after treatment. Always follow medical advice for proper dosing and safety.

Is there a human version of Fenbendazole?

+

Fenbendazole is not FDA-approved for humans but is being researched for potential cancer-fighting properties. Some people use veterinary versions off-label, though it\'s not medically recommended. Human-approved antiparasitic alternatives exist, and consulting a doctor is important before using any animal medications for human health.
