Ivermectin and Fenbendazole in the Treatment of Psoriasis? A Case Series of 13 Patients (2025)

By Dr Frank Yap, MD - October 03, 2025

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...

By Dr Frank Yap, MD - January 28, 2025

It’s natural to have complex feelings about noticing signs of aging.

If you’d like to soften these signs but don’t want to go the injectables route, there are non-invasive products that can help. In the world of beauty products, there's perhaps no category more saturated than the anti-aging market. What to Look for in an Anti-Aging Product a.

Triple G Agonists (Retatrutide): A Home Run for Obesity - NEJM

By Dr Frank Yap, MD - November 14, 2025

The New England Journal of Medicine - The buzz was palpable at the 2023 American Diabetes Association Scientific Sessions as multiple new nutrient-stimulated, hormone-based therapies for obesity and type 2 diabetes took center stage. Among these therapies, the triple–hormone-receptor agonist retatrutide — the subject of a phase 2 trial by Jastreboff et al., the results of which are published in this issue of the Journal 1 — showed unprecedented efficacy in treating obesity, with 24% weight loss over 48 weeks. Hormonal responses to nutrient intake are key regulators of metabolism. The best known is insulin secretion in response to postprandial increases in levels of glucose or amino acids, promoting nutrient storage and maintaining normoglycemia. In addition, intestinal hormonal responses to food intake further magnify insulin secretion (e.g., the “incretin effect” mediated by glucagon-like peptide-1 [GLP-1] and glucose-dependent insulinotropi...

12 Best Natural Ozempic Alternatives 2025 (Resource Guide)

By Dr Frank Yap, MD - November 13, 2025

Some of the best natural alternatives to Ozempic include berberine, a supplement that has shown potential in managing blood sugar and promoting weight loss, often referred to as “nature’s Ozempic” in wellness communities.

Additionally, green tea extract, magnesium, protein-rich foods, and lifestyle factors like adequate sleep and stress reduction contribute to weight management. However, none of these natural alternatives are as potent or fast-acting as Ozempic itself, and their effects can vary widely among individuals. It is important to consult a healthcare provider before starting any supplement regimen, especially for managing blood sugar or weight loss. The 2023 rep...
