KUKA FLEX CBD may be harmful due to hidden drug ingredient

Diclofenac is a non-steroidal anti-inflammatory drug (NSAID). NSAIDs may cause increased risk of cardiovascular events, such as heart attack and stroke, as well as serious gastrointestinal damage, including bleeding, ulceration and fatal perforation of the stomach and intestines. This hidden drug ingredient also may interact with other medications and significantly increase the risk of adverse events, particularly when consumers use multiple NSAID-containing products.

Health care professionals and consumers should report adverse events or side effects related to the use of this product to FDA’s MedWatch Safety Information and Adverse Event Reporting Program:

This notification is to inform the public of products potentially marketed as dietary supplements or conventional foods with hidden drug ingredients and chemicals. These products are typically promoted for sexual enhancement, weight loss, pain relief and body building and are often represented as being all natural. Consumers should exercise caution before purchasing these products.

FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients.
