During a recent therapy session, one of Dr. Norman Rosenthal's regulars said he was considering suicide. It wasn't the first time the patient had entertained the thought, and even though he was on antidepressants and always kept up with his appointments, Rosenthal, a licensed psychiatrist with a private practice in North Bethesda, Md., wanted to offer his patient something else.
A double-blind, placebo-controlled study enrolled patients who had extended histories of receiving and tolerating BOTOX injections, with prior individualized adjustment of dose. The mean BOTOX dose administered to patients in this study was 236 Units (25th to 75th percentile range of 198 Units to 300 Units). The BOTOX dose was divided among the affected muscles [see Clinical Studies].
Migraine with visual aura involves visual effects that usually precede the headache and last at least 5 minutes. The visual aura is usually an expanding blinding spot or visual scintillations (shimmering objects in the visual field). Other aura features include reversible symptoms of speech and language difficulty such as word-finding problems and aphasia (inability to express words or comprehend words), sensory phenomena such as tingling in the extremities extending to the face, motor effects such as weakness, and brainstem problems such as unsteadiness and features of cranial nerve dysfunction. These aura symptoms usually last 5 to 60 minutes, can precede or start during the headache, and can also occur without a headache.
There have been reports following administration of BOTOX® of adverse events involving the cardiovascular system, including arrhythmia and myocardial infarction, some with fatal outcomes. Some of these patients had risk factors including pre-existing cardiovascular disease. Use caution when administering to patients with pre-existing cardiovascular disease.
In the mid- to late-1990’s dermatologists were the first to report headache relief to migraineurs who were receiving BOTOX injections to reduce facial (forehead) wrinkles. Initially there was significant controversy about whether BOTOX really did help migraine patients. The use of BOTOX for treatment of tension headaches was studied and found to be no more effective than placebo. With migraines, it was more complex. In 2009 the data showed that BOTOX injected in particular areas of the head and neck in patients who met the International Classification of Headache Disorders criteria for chronic migraine provided sufficient benefit to recommend the treatment modality. In 2010, the FDA approved BOTOX for chronic migraine and recommended the protocol of injections and treatment frequency that had been successful in the studies.
