Why Was Kenalog Taken Off The Market?

Triamcinolone is a glucocorticoid that is more commonly known by the brand names Kenalog-10 Kenalog-40, Aristocort, Aristocort Forte, Aristospan, Clinacort, Triamcot, Triam-Forte, and Triesense.

Kenalog is used to treat inflammation (swelling), allergic reactions, certain types of arthritis, gout, skin diseases, and many other medical problems. Triamcinolone was patented in 1956 and came into medical use in 1958. In 2019, it was the 107th most commonly prescribed medication in the United States, with more than 6 million prescriptions.

Kenalog was first approved by the Food and Drug Administration (FDA) in 1958, so it’s been around for a long time. It is available as an injection but it is also available in topical forms (creams, lotions, ointments), nasal spray, dental paste. It works by controlling inflammation and calming overactive immune systems.

Is Kenalog Banned?

Triamcinolone the active ingredient in Kenalog is classified as an S9 glucocorticoid in the 2014 Prohibited List published by the World Anti-Doping Agency, which caused it to be prohibited in international athletic competition when administered orally, intravenously, intramuscularly, or rectally.

Why was Kenalog taken off the market?

Kenalog is off the UK market because, in October 2019, regulators withdrew the drug’s license to be used as a hay fever treatment in the UK. The National Health Service a publicly funded healthcare system in England, had previously warned against the use of Kenalog for more than a decade due to the risk of side effects such as a life-threatening allergic reaction in some people called anaphylaxis, hypertension, and increased susceptibility to infection. Kenalog may also delay growth in children.
