Common Name:

botulinum toxin type A


How does Xeomin work? What will it do for me?

Botulinum toxin is a neuromuscular paralytic agent. It blocks the nerves that are responsible for muscle activity and helps to relax muscles that are in constant contraction (spasm). It is used to treat conditions that are caused by certain muscles going into spasm. These include:

  • blepharospasm, a condition where the eyelid will not stay open because of a muscle spasm in the eye
  • cervical dystonia, also known as spasmodic torticollis, a condition in which the muscles of the neck stay in a state of contraction
  • spasticity of the upper limb (arm or hand) after a stroke

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop receiving this medication without consulting your doctor.

What form(s) does Xeomin come in?

XEOMIN® is supplied in sterile vials containing 100 units of Clostridium botulinum neurotoxin type A, free from complexing proteins. Nonmedicinal ingredients: sucrose and human serum albumin. This product contains no preservative.

How should I use Xeomin?

Botulinum toxin is injected into a muscle by a qualified health professional. When given for conditions of the eye, the medication is injected into the surrounding muscle or tissue of the eye.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications.
