This is an informed consent document that has been prepared to help your plastic surgeon inform you concerning Kybella™, its risks and alternative treatment(s). It is important that you read this information carefully and completely.  Please initial each page, indicating that you have read the page and sign the consent for Kybella as proposed by your plastic surgeon.



KYBELLA™ (deoxycholic acid) injection is indicated for improvement in the appearance of moderate to severe convexity or fullness associated with submental fat, also called “double chin,” in adults. The safe and effective use of KYBELLA™ for the treatment of subcutaneous fat outside the submental region has not been established and is not recommended.



Alternative forms of management consist of not treating the fat under the chin.  Improvement of the fatty deposits may be attempted by other treatments or surgery such as Liposuction of the neck or radiofrequency skin tightening. Risks and potential complications are associated with alternative forms of treatment.



Every procedure involves risk and it is important to understand these risks and the possible complications associated with them. In addition, every procedure has limitations.  An individual’s choice to undergo this procedure is based on the comparison of the risk to potential benefit.  Although the majority of patients do not experience the following, you should discuss each of them with your physician to make sure you understand the risks, potential complications, limitations, and consequences of Kybella™ injections.




Bleeding and Bruising:

It possible, though unusual, to have a bleeding episode from an injection or local anesthesia used during the procedure.  Bruising in soft tissue commonly occurs with Kybella™ injections.  Should you develop post-injection bleeding, it may require emergency treatment.  Aspirin, anti-inflammatory medications, platelet inhibitors, anticoagulants, Vitamin E, ginko biloba and other “herbs/homeopathic remedies” may contribute to a great risk of bleeding problems.  Do not take any of these for seven days before or after treatment.





Swelling (edema) is a normal occurrence following the injections. It decreases after a few days.  If swelling is slow to resolve, medical treatment may be necessary.



Discomfort associated with injections is normal and usually of short duration.


Needle Marks:

Visible needle marks from the injections occur normally and resolve in a few days.


Skin Sensitivity:

Skin rash, itching, tenderness, and swelling, bruising, pain, numbness, redness, tingling, nodule, itching, skin tightnessand areas of hardness in the treatment area may occur following injections.  After treatment, you should minimize exposure of the treated area to excessive sun or UV lamp exposure and extreme cold weather until any initial swelling or redness has gone away. If you are considering laser treatment, chemical peel or any other procedure based on a skin response after treatment, or you have recently had such treatments and the skin has not healed completely, there is a possible risk of an inflammatory reaction at the implant site.


Erythema (Skin Redness):

Erythema in the skin occurs after injections.  It can be present for a few days after the procedure.



Although infection following injection of Kybella™ is unusual, bacterial, fungal, and viral infections can occur.  Herpes simplex virus infections around the mouth can occur following a treatment.  This applies to both individuals with a past history of herpes simplex virus infections and individuals with no known history of herpes simplex virus infections in the mouth area.  Specific medication must be prescribed and taken both prior and following the treatment procedure in order to suppress an infection from this virus.  Should any type of skin infection occur, additional treatment including antibiotics may be necessary.


Under/Over Correction:

The injection of Kybella™ to improve the “double chin” may not achieve the desired outcome.  The amount of correction may be inadequate or excessive.  It may not be possible to control the symmetry due to factors attributable to each patient’s situation.



The human face is normally asymmetrical in its appearance and anatomy.  It may be possible to achieve or maintain exact symmetry.  There can be a variation from one side to the other in terms of response to injection.  This may require additional injections.




Damage to Deeper Structures:

Deeper structures such as nerves and blood vessels may be damaged during the course of injection.  Injury to deeper structures may be temporary or permanent.


Skin Lumpiness:

Lumpiness can occur following the injection of Kybella™.  This tends to smooth out over time. 



Painful masses in the skin and deeper tissues are extremely rare.  Should these occur, additional treatments including surgery may be necessary. Kybella should not be used in areas with active inflammation or infections (e.g. cysts, pimples, rashes, or hives).


Skin Necrosis:

It is very unusual to experience death of skin and deeper soft tissues after injections.  Skin necrosis can produce unacceptable scarring.  Should this complication occur, additional treatments or surgery may be necessary.


Allergic Reactions and Hypersensitivity:

As with all biologic products, allergic and systemic anaphylactic reactions may occur.  Kybella should not be used in patients with a history of multiple severe allergies, severe allergies manifested by a history of anaphylaxis, or known allergies to the chemicals in Kybella™


Drug and Local Anesthetic Reactions:

There is a possibility that a systemic reaction could occur from either the local anesthetic or epinephrine used for sensory nerve block anesthesia when Kybella™ injections are performed. This would include the possibility of light-headedness, rapid heartbeat (tachycardia), and fainting.  Medical treatment of these conditions may be necessary.


Antibodies to Kybella™

Presence of antibodies to Kybella™ may reduce the effectiveness of this material or produce a reaction in subsequent injections.  The health significance of antibodies to Kybella™ is unknown.


Accidental Intra-Arterial Injection/Marginal Mandibular Nerve Injection:

It is extremely rare that during the course of injection that Kybella™ could be accidentally injected into arterial structures and produce a blockage of blood flow.  This may produce skin necrosis in facial structures or damage blood flow to the eye, resulting in some loss of vision. The risk and consequences of accidental intravascular injection of Kybella™ is unknown and not predictable.  Kybella™ injections could cause nerve injury in the area of the jaw resulting in an uneven smile or facial muscle weakness.  In clinical trials these all resolved without treatment in an average of 6 weeks.





Kybella™ should not be used in patients with known susceptibility to keloid formation or hypertrophic scarring.  The safety of patients has not been studied.


Swallowing (Dysphagia):

KYBELLA™ injections can temporarily cause trouble with swallowing. Patients with a current or history of Dysphagia should not be treated with Kybella™.


Skin Ulceration:

KYBELLA™ injections could cause superficial skin erosions.



KYBELLA™ injections could cause small patches of alopecia in the treatment area.


Unsatisfactory Results:

There is a possibility of an unsatisfactory result from injections of KYBELLA™.  The procedure may result in unacceptable visible deformities or asymmetry in the treatment area. Additional injections may be necessary.  Surgical procedures or other treatments may be recommended along with additional treatments.


Unknown Risks:

The long term effects of Kybella™ beyond 1 year are unknown.  The possibility of additional risk factors or complications attributable to the use of Kybella™ as an improvement in the appearance of moderate to severe convexity or fullness associated with submental fat may be discovered.


Pregnancy and Nursing Mothers:

Animal reproduction studies have not been performed to determine if Kybella™ could produce fetal harm.  It is not known if Kybella™ or its breakdown products can be excreted in human milk.  It is not recommended that pregnant women or nursing mothers receive Kybella™ treatments.


Drug Interactions:

It is not known if Kybella reacts with other drugs within the body.


Long-Term Effects:



Additional Treatment Necessary:

There are many variable conditions in addition to risks and potential complications that may influence the long-term results of Kybella™ injections.  Even though risks and complications occur infrequently, the risks cited are the ones that are particularly associated with Kybella™ injections. Other complications and risks can occur but are even more uncommon.  Should complications occur, additional surgery or other treatments may be necessary.  The practice of medicine and surgery is not an exact science.  Although good results are expected, there is no guarantee or warranty expressed or implied, on the results that may be obtained.
