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
    or prickling
•   Diarrhea
•   Dizziness or vertigo
•   Nausea and vomiting
•   Scalp tenderness
•   Sensitivity to light or sound
•   Throbbing or pounding pain, often on one side of the head

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
•  Nausea
•  Vomiting
•  Diarrhea

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.
