Illegal Cancer Products - Fraudulent Claims of Cancer Prevention, Diagnosis, Treatment, or Cure

**Due to an update in May 2019 to the FDA.gov website, provided links may not appropriately redirect. Please visit www.fda.gov/drugs/drug-safety-and-availability to see the most recent FDA Medication Safety Alerts and Safety Communications or to search for specific alerts or communications.**

FDA is warning consumers and health care professionals that several companies have sold products illegally claiming to prevent, diagnose, treat, or cure cancer. These claims are a direct violation of the Federal Food, Drug and Cosmetic Act because these products have not demonstrated safety and efficacy required for FDA approval. In addition to potentially causing direct harm to patients with unsafe ingredients, these products may delay patients from receiving evidence-based cancer treatments. Some companies marketed the products for humans and pets. Most of the products are sold on the internet, including social media platforms or product websites. The illegal products include many formulations such as pills, creams, drops, syrups, and teas.

FDA issued 14 warning letters and 4 online advisory letters for more than 65 products. A list of the 18 companies and their products is included in a link below (List of illegally sold cancer treatments). The companies have 15 business days to respond to the warning letter stating how they will correct the violation. FDA will pursue further legal action if needed. Do not use these or similar products because they may be ineffective and unsafe. Encourage patients to avoid purchasing products without proof of efficacy and to always consult their health care professional when considering non-prescription products. Report adverse effects to the FDA MedWatch Adverse Event Reporting Program.
