Risks & Complications
Neuromodulator injections may cause serious side effects, which in rare cases can be life-threatening. It is essential that these treatments are administered only by a properly qualified physician or by a nurse working under a physician’s supervision.
Seek immediate medical attention or contact your healthcare provider right away if you experience any concerning symptoms at any time—ranging from hours to weeks—after receiving a neuromodulator injection.
Bleeding, which in rare instances could require hospitalization and blood transfusion. Blood clotsmay form under the skin and require drainage.
You are at the highest risk if these problems are pre-existing before injection.
Swallowing problems may last for several months
Allergic or Adverse Reactions
Although uncommon, immediate allergic reactions have been reported.
Possible symptoms include itching, rash, hives, wheezing, asthma-like symptoms, dizziness, or fainting.
If you experience any of these symptoms, contact your doctor or seek emergency medical care right away.
Spread of toxin effects.
The effects of neuromodulator injections may, in rare cases, extend beyond the injection site and cause serious symptoms.
Seek medical attention immediately if you experience difficulty swallowing, speaking, or breathing, or if you notice muscle weakness in areas away from where the injections were given.

Medical Conditions to Discuss with Your Provider
Tell your healthcare professional about any existing medical conditions, including:

Any diseases that affect muscles or nerves (for example, amyotrophic lateral sclerosis, myasthenia gravis, or Lambert-Eaton syndrome).

Weakness of facial muscles or difficulty raising your eyebrows.

Plans to have surgery, or a history of facial surgery.

Pregnancy or breastfeeding status (it is not known if neuromodulator products can affect an unborn baby or pass into breast milk).
Medications to Disclose
Before treatment, inform your healthcare provider about all medications you are taking, including prescription drugs, over-the-counter products, vitamins, and herbal supplements.
Using neuromodulator injections with certain medications—such as muscle relaxants, antibiotics given by injection, or blood thinners—may increase the risk of side effects.
