On September 5, 2025, the FDA advised consumers not to purchase or use FTX PLUS, a product promoted for joint pain on various websites, including Walmart and possibly in some retail stores. The FDA stated that its tests of FTX PLUS to contain found it to contain dexamethasone phosphate and diclofenac, drugs which are not listed on the label and not permitted as ingredients in dietary supplements.

(See ConsumerLab’s Joint Health Supplements Review for tests of related products.)

Dexamethasone is a prescription corticosteroid drug that has the potential to cause severe and serious adverse events, including adrenal suppression, a disorder in which the adrenal glands do not produce enough hormones, and other adverse events, which can lead to death. Sudden discontinuation of dexamethasone can also cause potentially dangerous withdrawal symptoms. Diclofenac is an anti-inflammatory drug that can cause heart attack, stroke, heart failure and death, especially among people with pre-existing susceptibility for heart disease. The drug should not be used by people with a history if stroke or heart attack, elderly individuals, people with kidney insufficiency, women who are pregnant, and those with a history of GI bleeds or ulcers. When applied to the skin, diclofenac can cause mild to moderate skin irritation.

Consumers should contact their healthcare provider if they have experienced any adverse side effects. Consumers and healthcare providers are also encouraged to report any adverse reactions to the FDA's MedWatch Adverse Event Reporting Program.
