1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In two double-blind, placebo-controlled clinical trials 513 subjects were treated with KYBELLA injection and 506 subjects were treated with placebo.
The population was 19-65 years old, 85% were women, 87% Caucasian, 8% African American.
At baseline the population had a mean BMI of 29 kg/m 2 , moderate to severe submental convexity (graded as 2 or 3 on a 0 to 4 scale) and without excessive skin laxity.
Subjects received up to 6 treatments at least 1 month apart and were followed for up to 6 months after the last received treatment.
The most commonly reported adverse reactions are listed below ( Table 1 ).

Adverse reactions that lasted more than 30 days and occurred in more than 10% of subjects were injection site numbness (42%), injection site edema/swelling (20%), injection site pain (16%), and injection site induration (13%).
5 WARNINGS AND PR E CAUTIONS Marginal mandibular nerve (MMN) injury: Follow injection technique to avoid this injury.
( 2.3 , 5.1 ) Dysphagia may occur with KYBELLA use.
Use in patients with pre-existing dysphagia may exacerbate the condition.
( 5.2 ) Submental hematoma/bruising occurs frequently after KYBELLA administration.
Use with caution in patients who are being treated with antiplatelet or anticoagulant therapy or have coagulation abnormalities.
Like all medications, Kybella can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
