Ivermectin and Fenbendazole in the Treatment of Psoriasis? A Case Series of 13 Patients (2026)

-
Image
Abstract Psoriasis is a chronic autoimmune condition affecting approximately 7.5 million individuals in the United States, with significant economic, physical, and psychological burdens. This case series reports on 13 patients who experienced notable improvements in psoriasis symptoms following treatment with ivermectin and/or fenbendazole, antiparasitic agents repurposed for this indication. Cases were derived from self-reported testimonials shared on social media platforms. Treatment durations ranged from 3 days to 3 months, with dosages varying between 6 mg ivermectin twice daily and combinations with fenbendazole. Rapid resolution of skin lesions was observed in most cases, with some achieving near-complete clearance. While these anecdotal reports suggest potential therapeutic efficacy, controlled clinical trials are warranted to validate these findings and elucidate underlying mechanisms. Introduction Psoriasis is a chronic inflammatory disorder characterized by hyperproliferation...

Nebulized Hydroxychloroquine for COVID-19 Treatment: 80x Improvement in Breathing - Vladimir Zelenko, M.D.

-
Image
Nebulized hydroxychloroquine as 150 mg HCQ in 6 ml (25 mg/ml) of isotonic sterile solution within the first five (5) days of COVID-19 symptoms (“Nebu HCQ”) has resulted in immediate improvement (<1 hour after use) in breathing in COVID-19 infected patients. Nebu HCQ served as a rescue medication with an 80x improvement in time and efficiency when compared to HCQ tablet (400-600 mg per day) combination therapy or Ivermectin combination therapy. No adverse events were reported outside of a bitter taste that quickly subsided. The protocol used is as follows: 6 ml (25 mg HCQ per ml) per nebulizer session (15 minutes). Two sessions (12 ml total) in the first hour for patients with mild to moderate pulmonary symptoms from COVID-19. Since March 2020, my team has successfully treated over 3,000 patients with COVID-19 with the Zelenko Protocol . Our high-risk patient survival rate was >99.3% (0.7% mortality) which represents a radical improvement when compared to national data of high-ri...

-
Image
Hydroxychloroquine, a less toxic derivative of Chloroquine is a widely used medication by people with lupus or arthritis. It was first approved in the 1950s.  Hydroxychloroquine (HCQ) is not effective when used very late with high dosages over a long period (RECOVERY/SOLIDARITY), effectiveness improves with earlier usage and improved dosing. Early treatment consistently shows positive effects. Negative evaluations typically ignore treatment time, often focusing on a subset of late stage studies. As of April 2022, there have been more than 30 studies of Hydroxychloroquine for early treatment – all with zero negative results for the most serious outcome reported. The average risk reduction for the most serious outcome reported in these trials was 63%. ( c19hcq.com )   Here’s a chart from  c19early.com   that shows that hydroxychloroquine performs better than ivermectin when given as early treatment in terms of risk reduction of dying from COVID-19: The overall im...
