Risks of Minoxidil Toxicity for Household Pets

Topical minoxidil, a common hair loss treatment, poses a significant and increasing risk to household pets, especially cats. A study analyzing 701 cases reported to the ASPCA Poison Control from 2013 to 2024 found that 46% of exposed pets developed toxicity, with five cat fatalities. The rise in pet exposures correlates with increased public interest in minoxidil, as shown by Google Trends data. Most exposures occur through oral ingestion due to pets' exploratory behavior. The study highlights the urgent need for better public education, clearer product labeling, and safety precautions to prevent accidental pet poisonings.
