XEOMIN is a prescription medicine that is injected into muscles and used:
" treat the abnormal head position and neck pain that happens with cervical dystonia (CD) in adults.
" to treat abnormal spasm of the eyelids (blepharospasm) in adults who have had prior treatment with onabotulinumtoxinA (Botox®).
What is XEOMIN?
XEOMIN is a botulinum toxin that is used to treat adults with cervical dystonia and blepharospasm. It has been used around the world since 2005 and was introduced to the US market in 2010 by Merz Pharmaceuticals, LLC.
How does XEOMIN work?
XEOMIN is injected into muscles to decrease their activity. XEOMIN blocks the release of a chemical messenger-acetylcholine-that conveys the signal from nerve terminals and causes muscle fibers to contract. Not all terminals are affected by botulinum toxin, so the muscles can still contract, just less forcefully. This allows the muscles to contract more normally.
IMPORTANT SAFETY INFORMATION
may cause serious side effects that can be life threatening. Call your doctor or get medical help right away if you have any of these problems any time (hours to weeks) after treatment with XEOMIN:
- Problems with swallowing, speaking, or breathing can happen after an injection of XEOMIN® if the muscles that you use to breathe and swallow become weak. If these problems are severe, you could die. People with certain breathing problems may need to use muscles in their neck to help them breathe and may be at greater risk for serious breathing problems with XEOMIN.
- Swallowing problems may last for several months, and during that time you may need a feeding tube to receive food and water. If swallowing problems are severe, food or liquids may go into your lungs. People who already have swallowing or breathing problems before receiving XEOMIN have the highest risk of getting these problems.
- Spread of toxin effects. In some cases, the effect of botulinum toxin may affect areas of the body away from the injection site and cause symptoms of a serious condition called botulism. The symptoms of botulism include: loss of strength and muscle weakness all over the body, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, trouble swallowing.
Do not take XEOMIN if you: are allergic to XEOMIN or any of the ingredients in XEOMIN; had an allergic reaction to any other botulinum toxin product such as rimabotulinumtoxinB (Myobloc), onabotulinumtoxinA (Botox, Botox Cosmetic), or abobotulinumtoxinA (Dysport); have a skin infection at the planned injection site.
Before you take XEOMIN, tell your doctor about all your muscle or nerve conditions, including if you have a disease that affects your muscles and nerves (such as amyotrophic lateral sclerosis [ALS or Lou Gehrig's disease], myasthenia gravis or Lambert-Eaton syndrome), as you may be at increased risk of serious side effects including difficulty swallowing or breathing.
Before you take XEOMIN, tell your doctor about all your medical conditions, including if you have: breathing problems such as asthma or emphysema; a history of swallowing problems or inhaling food or fluid into your lungs (aspiration); bleeding problems; drooping eyelids; plans to have surgery; had surgery on your face. Also tell your doctor if you are pregnant or plan to become pregnant (it is not known if XEOMIN can harm your unborn baby); are breastfeeding or plan to breastfeed (it is not known if XEOMIN passes into breast milk).
Tell your doctor about all the medicines you take, including prescription and nonprescription medicines, vitamins and herbal products. Using XEOMIN with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you have received XEOMIN in the past.
Especially tell your doctor if you have received any other botulinum toxin product in the last four months or in the past. Be sure your doctor knows exactly which product you received. The dose of XEOMIN may be different from other botulinum toxin products that you have received.
XEOMIN may cause loss of strength or general muscle weakness, blurred vision, or drooping eyelids within hours to weeks of taking XEOMIN. If this happens, do not drive a car, operate machinery, or do other dangerous activities. XEOMIN may cause other serious side effects including allergic reactions. Symptoms of an allergic reaction to XEOMIN may include: itching, rash, redness, swelling, wheezing, asthma symptoms, or dizziness or feeling faint.
