5 Warnings and Precautions

5.6 Injection site ulceration, necrosis, and infection

Additions and/or revisions underlined:

Injections that are too superficial (into the dermis) may result in skin ulceration and necrosis [see Injection Technique (2.3)]. Cases of injection site ulceration, necrosis, and infection have been reported with the administration of KYBELLA. Some cases of injection site infection have included cellulitis and abscess requiring intravenous antibiotic treatment and incision and drainage. Do not administer KYBELLA into the affected area until complete resolution of the adverse reaction.

6 Adverse Reactions

6.2 Postmarketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been identified during post-approval use of KYBELLA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to KYBELLA exposure.

Administration site conditions: injection site ulceration, necrosis, infection, alopecia, and scarring.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

17 PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Advise the patient to read the FDA-approved patient labeling (Patient Information).

Advise patients to contact their healthcare providers if patients begin to develop signs of marginal mandibular nerve paresis (e.g., asymmetric smile, facial muscle weakness), difficulty swallowing, or worsening of existing symptoms.

Advise patients to contact their healthcare providers for development of erythema, pain, open sore(s) or drainage from the treatment area.

6 Adverse Reactions

6.2 Postmarketing Experience

(Additions and/or revisions underlined)

The following adverse reactions have been identified during post-approval use of KYBELLA®. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to KYBELLA® exposure.

Administration site conditions: injection site ulceration, necrosis, alopecia, and scarring.

Immune System Disorders: Hypersensitivity reactions including rash, urticaria, and itching.

Nervous System Disorders: Oral hypoaesthesia and oral paraesthesia.

8 Use in Specific Populations

8.5 Geriatric Use

(Additions and/or revisions underlined)

The clinical trials of KYBELLA® did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT INFORMATION

(Additions and/or revisions underlined)

Call your healthcare provider if you:

  • begin to develop weakness in the muscles of your face, or your smile becomes uneven

  • you have difficulty swallowing, or if any of the symptoms that you already have get worse

  • develop open sores or drainage from the treatment area

The most common side effects of KYBELLA include:

  • swelling               redness

  • pain                     areas of hardness in the treatment area

  • numbness

These are not all of the possible side effects of KYBELLA.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

5 Warnings and Precautions

5.4 Risk of injecting in proximity to vulnerable anatomic structures

(Additions and/or revisions underlined)

To avoid potential tissue damage, KYBELLA® should not be injected into or in close proximity (1-1.5 cm) to salivary glands, lymph nodes and muscles.

Care should be taken to avoid inadvertent injection directly into an artery or a vein as it can result in vascular injury.

6 Adverse Reactions

6.2 Postmarketing Experience

(Additions and/or revisions underlined)

The following adverse reactions have been identified during post-approval use of KYBELLA®. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to KYBELLA® exposure.

Administration site conditions: injection site ulceration, necrosis, alopecia, and scarring.

Immune System Disorders: Hypersensitivity reactions including rash, urticaria, and itching.

Nervous System Disorders: Oral hypoaesthesia and oral paraesthesia.

Procedural Complications: Vascular injury due to inadvertent intravascular injection.

PATIENT INFORMATION

(Additions and/or revisions underlined)

What are the possible side effects of KYBELLA? KYBELLA can cause serious side effects, including:

  • Nerve injury in the jaw that can cause an uneven smile or facial muscle weakness

  • Trouble swallowing

  • Injection site problems including:

    • a collection of blood under the skin (hematoma) or bruising

    • damage to an artery or vein if KYBELLA is inadvertently injected into it

    • hair loss

    • open sores (ulcers)

    • damage and tissue cell-death (necrosis) around the injection site

4 Contraindications

(Additions and/or revisions are underlined)

KYBELLA® (deoxycholic acid) injection is contraindicated in the presence of infection at the injection sites.

5 Warnings and Precautions

5.1 Marginal mandibular nerve injury

(Additions and/or revisions are underlined)

Cases of marginal mandibular nerve injury, manifested as an asymmetric smile or facial muscle weakness (paresis), were reported during clinical trials. To avoid the potential for nerve injury, KYBELLA® (deoxycholic acid) injection should not be injected into or in close proximity to the marginal mandibular branch of the facial nerve…

5.5 Injection site alopecia

(Newly added subsection)

Cases of injection site alopecia have been reported with the administration of KYBELLA®. The onset and duration of this adverse reaction may vary among individuals and may persist. Consider withholding subsequent treatments until resolution of the adverse reaction.

5.6 Injection site ulceration and necrosis
