Kythera Biopharma, a biopharmaceutical company based in California, focuses on developing innovative pharmaceutical products to address unmet medical needs in medical aesthetic and therapeutic areas. Kybella, their FDA-approved product, is a prescription medicine used in adults to improve the appearance and profile of moderate to severe fat below the chin or submental fat, also known as a double chin. Uses: Kybella is designed to destroy the fat cells beneath the chin, leading to a noticeable reduction in the appearance of submental fat. Men and women who are dissatisfied with their double chin can get Kybella injected to contour their neck and achieve a more youthful and attractive profile. The active ingredient in Kybella is deoxycholic acid, a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat. Dosage: The dosage of Kybella depends on various factors, including submental fat volume, the desired aesthetic outcome, and the number of treatment sessions recommended by the physician. The treatment is typically administered in multiple, small injections under the chin, with each treatment separated by four weeks. Patients can receive up to six treatments to achieve the desired results. Side Effects: Kybella injections can cause several side effects, including swelling, bruising, pain, numbness, redness, and hardness in the treatment area. In rare cases, patients may experience difficulty swallowing, nerve injury, or an uneven smile. Patients should discuss any concerns with their physician. Interactions: Kybella injections should not be administered to patients with an infection in the treatment area or who have had facial surgery or cosmetic treatments done on the chin, neck, or face. Patients taking blood-thinning medications should also inform their physician before getting Kybella injections. Generic: Kybella is not available in generic form. The medication's active ingredient, deoxycholic acid, is synthetic, and there is no generic equivalent to Kybella. Demographic: Kybella is approved for use in adults over 18 years of age with moderate to severe submental fat. Patients seeking Kybella treatment should have a BMI (body mass index) of less than 43, no larger medical problems, and a realistic expectation of the results. Conclusion: Kybella is an effective and safe treatment to improve submental fat in men and women. The medication is administered in multiple, small injections under the chin, and patients can undergo up to six treatments. Kybella can cause swelling, bruising, pain, and redness in the treatment area, but these side effects are temporary and expected to resolve on their own. Patients should discuss the benefits and risks of Kybella treatment with their physician before receiving the medication.
