Xeomin (incobotulinumtoxinA) is an injectable medication used to treat many movement problems, drooling, and frown lines, but it can have dangerous side effects if it spreads to areas outside of the injection. It's typically administered by a healthcare provider.
Long-term excessive drooling (sialorrhea) in people 2 years and older
Arm spasms in people 2 years and older
Uncontrollable neck spasms (cervical dystonia) in adults
Uncontrollable eye twitching (blepharospasm) in adults
Frown lines in adults
Xeomin (incobotulinumtoxinA) is a neuromuscular blocker. It's a toxin made from bacteria (Clostridium botulinum) that temporarily lowers muscle activity by stopping a chemical called acetylcholine from being released in your muscle. This is helpful to treat muscle spasms that are caused by many different conditions as well as frown lines, twitching, and drooling.

Xeomin (incobotulinumtoxinA) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Children | History of muscle, eye, or lung conditions
Xeomin (incobotulinumtoxinA) has been linked to spreading to other body areas outside of the injection site and causing toxic effects, occurring hours to weeks after receiving Xeomin (incobotulinumtoxinA). This can cause serious side effects, such as unexplained muscle weakness, drooping eyelids, blurred or double vision, breathing or swallowing difficulty, slurred speech or trouble speaking, or the need to urinate more frequently. If you notice any of these side effects, seek medical help right away.
Risk factors: History of swallowing or breathing problems | Small neck muscles | Using Xeomin (incobotulinumtoxinA) in certain muscles | Myasthenia gravis | Lambert-Eaton syndrome | Current muscle-nerve conditions
Xeomin (incobotulinumtoxinA) can cause life-threatening problems with swallowing or breathing by weakening muscles involved in these functions, occurring hours to weeks after receiving Xeomin (incobotulinumtoxinA). These effects can last for many months. Your risk is higher if you have certain conditions affecting your muscles or nerves, or if you're injecting Xeomin (incobotulinumtoxinA) in certain muscles (e.g., sternocleidomastoid muscles). If you notice any of these problems, seek medical help right away. If you have a history of swallowing or breathing problems, let your provider know before receiving Xeomin (incobotulinumtoxinA).
Risk factors: Previous eye surgery | Certain nerve problems
Injecting Xeomin (incobotulinumtoxinA) in the eyelid muscle leads to reduced blinking, which can lead to eye problems like ulcers in your eye. You're at higher risk if you have a history of eye surgery or certain nerve problems. Your provider will make sure your eyes are okay and might prescribe an ointment or special contact lenses to protect your eye if there are any problems. Let your provider know if you exerience eye pain or irritation after receiving Xeomin (incobotulinumtoxinA).
Risk factors: History of angle-closure glaucoma
Xeomin (incobotulinumtoxinA) can cause worsening of certain types of glaucoma, since it can raise pressure in your eyes by dilating (widening) your pupils. Let your provider know if you have a history of glaucoma before starting Xeomin (incobotulinumtoxinA).
Risk factors: Using Xeomin (incobotulinumtoxinA) for frown lines | Using higher than recommended doses of Xeomin (incobotulinumtoxinA) | Using Xeomin (incobotulinumtoxinA) more frequently than recommended
Xeomin (incobotulinumtoxinA) can cause drooping eyelids in some people who use it to treat frown lines. Don't use Xeomin (incobotulinumtoxinA) more frequently than every 3 months to avoid this side effect. If you notice drooping eyelids after you receive Xeomin (incobotulinumtoxinA), let your provider know.
Xeomin (incobotulinumtoxinA) is only available as an injection that's administered by a healthcare provider. The dose will depend on the condition you have.
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. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
