The generic name for Kybella is deoxycholic acid [1].
What is deoxycholic acid used for?
Deoxycholic acid, marketed as Kybella, is an injectable prescription medicine used to improve the appearance of moderate to severe fat below the chin, also known as submental fat [2]. It works by destroying fat cells [3].
How does deoxycholic acid work?
Deoxycholic acid is a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat. When injected into the submental fat, it disrupts the fat cell membrane, leading to cell death. The body then gradually clears away these dead fat cells [3].
When will Kybella lose its patent protection?
Information on specific patent expiry dates for Kybella is available through resources like DrugPatentWatch.com [4]. Generally, patent protection for branded drugs can be extended through various mechanisms, but eventual patent expiry allows for the potential development of generic versions [4].
What are the risks of deoxycholic acid injections?
Common side effects of Kybella injections include swelling, bruising, pain, numbness, redness, and hardness in the treatment area [2]. More serious side effects are rare but can include nerve injury in the jaw that can cause an uneven smile or facial muscle weakness and difficulty swallowing [2][3].
Are there alternatives to Kybella for under-chin fat?
Other treatment options for submental fat include liposuction and non-surgical treatments like cryolipolysis (fat freezing) [5]. The choice of treatment often depends on individual patient goals, the amount of fat, and the desired outcome [5].
