If you experience migraine symptoms on 15 or more days each month, you have chronic migraines. Over-the-counter or prescription medications may help ease some of your symptoms, but some patients don’t respond well to pain relievers. In some cases, your doctor may prescribe preventive medicines, which are designed to reduce the frequency and severity of your symptoms. According to research published in the journal Neurology, only about one-third of patients with chronic migraines take preventive medicines.
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].
Botox® neurotoxin treatment helps control the symptoms of severe underarm sweating when topical medicines do not work well enough by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. When the sweat glands don’t receive chemical signals, the severe sweating stops. Botox® injections are expected to temporarily stop the production of excessive sweat in the treated areas only. Sweat continues to be produced elsewhere.
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 and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, trouble swallowing.
The most common side effect of the BOTOX procedure for migraines is neck pain. In clinical trials, 9 percent of patients reported this side effect. Other side effects can include headaches or muscle pain, but these side effects are far less common. If you do experience neck pain, an ice pack can help you manage the discomfort until it dissipates. At Allure Esthetic, we will perform the BOTOX for migraines procedure carefully and correctly.
In the mid-1990s, people who received BOTOX for other conditions reported improvement in their chronic migraine pain. A two-phase study was conducted, treating patients who averaged 20 headache days a month. They received BOTOX injections every twelve weeks for 56 weeks. At the end of that period, 70% of the patients had fewer than half the number of headaches they had before treatment. The FDA officially approved BOTOX to treat chronic migraine in October of 2010. Since then, more than 100,000 patients have been treated.
In a study to evaluate inadvertent peribladder administration, bladder stones were observed in 1 of 4 mal e monkeys that were injected with a total of 6.8 Units/kg divided into the prostatic urethra and proximal rectum (single administration). No bladder stones were observed in male or female monkeys following injection of up to 36 Units/kg (~12X the highest human bladder dose) directly to the bladder as either single or 4 repeat dose injections or in female rats for single injections up to 100 Units/kg (~33X the highest human bladder dose).
There has not been a confirmed serious case of spread of toxin effect away from the injection site when BOTOX® has been used at the recommended dose to treat chronic migraine, severe underarm sweating, blepharospasm, strabismus, or when BOTOX® Cosmetic has been used at the recommended dose to treat frown lines, crow’s feet lines, and/or forehead lines.
