USE
BOTOX® (onabotulinumtoxinA) is a prescription medicine that is injected into muscles and used to treat increased muscle stiffness in people 2 years of age and older with spasticity.
BOTOX has not been shown to help people perform task-specific functions with their upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles.
IMPORTANT SAFETY INFORMATION
BOTOX may cause serious side effects that can be life threatening. Get medical help right away if you have any of these problems any time (hours to weeks) after injection of BOTOX:
- Problems swallowing, speaking, or breathing, due to weakening of associated muscles, can be severe and result in loss of life. You are at the highest risk if these problems are preexisting before injection. Swallowing problems may last several months.
- Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms, including loss of strength and all-over muscle weakness; double vision; blurred vision; drooping eyelids; hoarseness or change or loss of voice; trouble saying words clearly; loss of bladder control; trouble breathing; and trouble swallowing.
BOTOX may cause loss of strength or general muscle weakness, vision problems, or dizziness within hours to weeks of receiving BOTOX. If this happens, do not drive a car, operate machinery, or do other dangerous activities.
Do not receive BOTOX if you are allergic to any of the ingredients in BOTOX (see Medication Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as Myobloc® (rimabotulinumtoxinB), Dysport® (abobotulinumtoxinA), or Xeomin® (incobotulinumtoxinA); have a skin infection at the planned injection site.
The dose of BOTOX is not the same as, or comparable to, another botulinum toxin product.
Serious and/or immediate allergic reactions have been reported, including itching; rash; red, itchy welts; wheezing; asthma symptoms; dizziness; or feeling faint. Get medical help right away if you experience symptoms; further injection of BOTOX should be discontinued.
Tell your doctor about all your muscle or nerve conditions, such as 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 and difficulty breathing from typical doses of BOTOX.
Tell your doctor if you have any breathing-related problems. Your doctor may monitor you for breathing problems during your treatment with BOTOX for spasticity. The risk of developing lung disease in patients with reduced lung function is increased in patients receiving BOTOX.
Bronchitis and upper respiratory tract infections (common colds) have been reported. Bronchitis was reported more frequently in adults receiving BOTOX for upper limb spasticity. Upper respiratory infections were also reported more frequently in adults with prior breathing-related problems with spasticity. In pediatric patients treated with BOTOX for upper limb spasticity, upper respiratory tract infections were reported more frequently. In pediatric patients treated with BOTOX for lower limb spasticity, upper respiratory tract infections were not reported more frequently than placebo.
Tell your doctor about all your medical conditions, including if you have or have had bleeding problems; have plans to have surgery; had surgery on your face; have weakness of forehead muscles, trouble raising your eyebrows, drooping eyelids, and any other abnormal facial change; are pregnant or plan to become pregnant (it is not known if BOTOX can harm your unborn baby); are breastfeeding or plan to (it is not known if BOTOX passes into breast milk).
Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Using BOTOX with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you received BOTOX in the past.
Tell your doctor if you received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (tell your doctor exactly which product you received); have recently received an antibiotic by injection; take muscle relaxants; take an allergy or cold medicine; take a sleep medicine; take aspirin-like products or blood thinners.
Other side effects of BOTOX include dry mouth; discomfort or pain at the injection site; tiredness; headache; neck pain; eye problems such as double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of your eyelids, and dry eyes; drooping eyebrows; and upper respiratory tract infection.
