BOTOX® (onabotulinumtoxinA) is a prescription medicine that is injected to prevent headaches in adults with chronic migraine who have 15 or more days each month with headache lasting 4 or more hours each day in people 18 years or older.
Abnormal muscle spasms
Contractures and movement disorders following strokes
Traumatic injuries to the brain, spinal cord, and peripheral nerves
BOTOX® Injections. In some people with TMJ disorder, injecting Botulinum Neurotoxin Type A (Botox) into the jaw muscles can relieve bruxism (involuntary clenching of the teeth). This relaxes the chewing muscles and lessens the strain on the temporomandibular joints (TMJ). Grinding of the teeth is thereby reduced by the amelioration of jaw clenching. This treatment should be repeated every three to four months. Your dentist or oral surgeon can also give you advice on managing this disorder.
• Abnormal body sensations, called paresthesias, such as tingling, numbing
• Dizziness or vertigo
• Nausea and vomiting
• Scalp tenderness
• Sensitivity to light or sound
• Throbbing or pounding pain, often on one side of the head
• Visual disturbances, such as flashes of light or blind spots in your vision
• Worsening of pain with movement
Taking certain medicines together can cause a serious but uncommon condition called serotonin syndrome. The problem can happen if you are taking a triptan, used for migraines, along with an antidepressant medicine such as an SSRI or an SNRI.
SSRIs are selective serotonin reuptake inhibitors, and SNRIs are selective serotonin/norepinephrine reuptake inhibitors. Symptoms of serotonin syndrome may include:
• Restless feelings
• Clumsiness or loss of coordination
• Hallucinations (seeing or hearing things)
• Rapid heart rate
• Raised body temperature
If you are taking a triptan along with an antidepressant and you notice any of these symptoms, call your doctor right away. Without treatment, serotonin syndrome can be deadly. But treatment usually can get rid of the symptoms in less than 24 hours.
