Description
IncobotulinumtoxinA is used to treat the abnormal head position and neck pain that result from cervical dystonia (severe muscle spasms of the neck). It is also used to treat upper limb spasticity (muscle spasms in the upper arms). This medicine is also used to treat blepharospasm, a condition wherein the eyelid will not stay open because of a muscle spasm. It is also used to treat long-lasting sialorrhea (excessive drooling). IncobotulinumtoxinA is also used cosmetically to improve the appearance of upper facial lines or wrinkles (including glabellar lines, horizontal forehead lines, and lateral canthal lines) for a short period of time.
IncobotulinumtoxinA is a botulinum toxin A product. It works on the nervous system to relax the muscles.
This medicine is to be given only by or under the direct supervision of your doctor.
This product is available in the following dosage forms:
- Powder for Solution
Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of incobotulinumtoxinA in children with lower limb spasticity, cervical dystonia, blepharospasm, or upper facial lines. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of incobotulinumtoxinA in children 2 to 17 years of age with sialorrhea or upper limb spasms, excluding spasms caused by cerebral palsy. Safety and efficacy have not been established in children younger than 2 years of age.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of incobotulinumtoxinA in the elderly. However, elderly patients are more sensitive to the effects of this medicine than younger adults and are more likely to have side effects (eg, difficulty with swallowing, lack or loss of strength, or dizziness), which may require caution in patients receiving incobotulinumtoxinA.
Breastfeeding
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Drug Interactions
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Proper Use
Your doctor will give you this medicine in a medical facility. It is given as a shot into one of your muscles or as a needle placed into your saliva gland.
This medicine should come with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.
Your doctor will only use incobotulinumtoxinA (Xeomin®) to treat your condition. Other botulinum toxin products may not work the same way.

You may see the effects of this medicine for your condition within 7 days after the injection, which may last up to 12 to 16 weeks. However, the duration of the effects may differ from person to person.
Precautions
It is very important that your doctor check your progress closely and at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it.
Serious muscle reactions have occurred within hours to weeks after receiving this medicine. If you start to have muscle weakness, loss of bladder control, or trouble with swallowing, talking, or breathing, call your doctor right away. In some patients, these problems could be life-threatening and may require treatment in a hospital or clinic.
This medicine may cause serious allergic reactions, including anaphylaxis and serum sickness, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, hives, itching, hoarseness, trouble breathing or swallowing, fever, joint swelling, muscle aches, or any swelling of your hands, face, or mouth while you are receiving this medicine.
This medicine may make your muscles weak and cause eye or vision problems (eg, bleeding inside the eye). Do not drive or do anything else that could be dangerous until you know how this medicine affects you.
This medicine may reduce blinking of the eye which can lead to an increased risk of eye problems (eg, corneal exposure and ulcers). Tell your doctor right away if you have a reduced blinking of the eye.
After you have received this medicine and your vision or muscle spasms get better, you may find that you are a lot more active than you were before. You should slowly increase your activities to allow time for your body to get stronger. Also, before you start an exercise program, talk with your doctor.
A part of this medicine is made from donated human blood. Some human blood products have transmitted certain viruses to people who have received them, although the risk is low. Human donors and donated blood are both tested for viruses to keep the transmission risk low. Talk with your doctor about this risk if you are concerned.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
