KYBELLA® can cause serious side effects, including but not limited to:
- Nerve injury in the jaw (which can cause an uneven smile or facial muscle weakness).
- Trouble swallowing.
- Injection site problems including: bruising, hair loss, open sores (ulcers), damage and tissue cell-death (necrosis) around the injection site. Call your healthcare provider if you develop open sores or drainage from the treatment area.
The most common side effects of KYBELLA® include:
- Areas of hardness in the treatment area.
These are not all of the possible side effects of KYBELLA®. Call your doctor for medical advice about side effects.
WARNINGS AND PRECAUTIONS
Marginal Mandibular Nerve Injury
Cases of marginal mandibular nerve injury, manifested as an asymmetric smile or facial muscle weakness, were reported in 4% of subjects in the clinical trials; all cases resolved spontaneously (range 1-298 days, median 44 days). KYBELLA® should not be injected into or in close proximity to the marginal mandibular branch of the facial nerve.
Dysphagia occurred in 2% of subjects in the clinical trials in the setting of administration-site reactions, eg, pain, swelling, and induration of the submental area; all cases of dysphagia resolved spontaneously (range 1-81 days, median 3 days). Avoid use of KYBELLA® in patients with current or prior history of dysphagia as treatment may exacerbate the condition.
In clinical trials, 72% of subjects treated with KYBELLA® experienced hematoma/bruising. KYBELLA® should be used with caution in patients with bleeding abnormalities or who are currently being treated with antiplatelet or anticoagulant therapy as excessive bleeding or bruising in the treatment area may occur.
Risk of Injecting Into or in Proximity to Vulnerable Anatomic Structures
To avoid the potential of tissue damage, KYBELLA® should not be injected into or in close proximity (1 cm-1.5 cm) to salivary glands, lymph nodes, and muscles.
Injection Site Alopecia
Cases of injection site alopecia have been reported with administration of KYBELLA®. Onset and duration may vary among individuals and may persist. Consider withholding subsequent treatments until resolution.
Injection Site Ulceration and Necrosis
Injections that are too superficial into the dermis may result in skin ulceration and necrosis. Cases of injection site ulceration and necrosis have been reported with administration of KYBELLA®. Do not administer KYBELLA® into affected area until complete resolution.
The most commonly reported adverse reactions in the pivotal clinical trials were: injection site edema/swelling, hematoma/bruising, pain, numbness, erythema, and induration.
