A recent encounter with one of my headache patients got me thinking. I am treating this young woman for chronic migraine with BOTOX injections. She told me that one of her other physicians had been surprised to hear about this use for onabotulinumtoxin A. According to my patient, the gastroenterologist’s words were, “BOTOX for migraines? I’ve never heard of that.” 
For blepharospasm, reconstituted BOTOX is injected using a sterile, 27-30 gauge needle without electromyographic guidance. The initial recommended dose is 1.25 Units-2.5 Units (0.05 mL to 0.1 mL volume at each site) injected into the medial and lateral pre tarsal orbicularis oculi of the upper lid and into the lateral pre-tarsal orbicularis oculi of the lower lid. Avoiding injection near the levator palpebrae superioris may reduce the complication of ptosis. Avoiding medial lower lid injections, and thereby reducin g diffusion into the inferior oblique, may reduce the complication of diplopia. Ecchymosis occurs easily in the soft eyelid tissues. This can be prevented by applying pressure at the injection site immediately after the injection.

In the third study, 25 patients with chronic migraine were injected with 12.5 doses of botox into each trigger point twice, during a period of 3 months. Frequency (main variable), intensity and scales of migraine crises were recorded one month before and one month after the treatment to compare the changes experienced. In addition, side effects were also recorded during the experiment, and they were found to be mild and temporary.
There's been a pivotal shift in how women in their 20s look at their faces. And while the reasons are arguably as multi-faceted as this new generation itself, many would agree on one thing: The impact of social media, from selfies to YouTube videos to meticulously crafted Snapchat and Insta Stories, combined with endlessly retouched photographs in magazines and ad campaigns, can not be underestimated. From the constant stream of supernaturally smooth jawlines and chiseled cheekbones to celebrity plastic surgeons posting before-and-after images of their work, the age of 24/7 self-documentation has spurred a novel set of beauty ideals—and, with it, a dramatic increase in cosmetic procedures. For 20-somethings, there's no treatment more popular—or controversial—than Botox. Need proof? According to the American Society of Plastic Surgeons, botulinum toxin procedures have increased 28 percent since 2010 amongst 20 to 29-year-olds.
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].

Many times, effects on spasticity are longer lasting. It is not clear if this is due to breaking down patterned movements (many muscles contracting together rather than singly) or from allowing weak muscles to get stronger over time (that were overpowered before by more spastic muscles pulling against them). It is vital to have close follow-up after the injections to figure out the best course of treatment.
The recommended dilution is 200 Units/4 mL or 100 Units/2 mL with preservative -free 0.9% Sodium Chloride Injection, USP (see Table 1). The lowest recommended starting dose should be used, and no more than 50 Units p er site should generally be administered. An appropriately sized needle (e.g., 25-30 gauge) may be used for superficial muscles, and a longer 22 gauge needle may be used for deeper musculature. Localization of the involved muscles with techniques such as needle electromyographic guidance or nerve stimulation is recommended.
In 1986, Scott's micromanufacturer and distributor of Botox was no longer able to supply the drug because of an inability to obtain product liability insurance. Patients became desperate, as supplies of Botox were gradually consumed, forcing him to abandon patients who would have been due for their next injection. For a period of four months, American blepharospasm patients had to arrange to have their injections performed by participating doctors at Canadian eye centers until the liability issues could be resolved.[48]
Wrinkles, whether they be fine line or deep furrows, typically appear on areas of the body that receive a high amount of exposure to the sun. Smoking, light skin type, hairstyle, the way you dress, your occupational and recreational habits, and heredity are all factors that promote wrinkling. Medical treatments for wrinkles include antioxidants, moisturizers, alpha-hydroxy acids, and vitamin A acid. Cosmetic procedures that treat wrinkles include dermabrasion, microdermabrasion, glycolic acid peels, laser resurfacing, Botox, and fillers.
Although one cannot predict exactly who will respond, I find that those patients who are going to respond will note some improvement in headaches following the first set of injections. Repeat injection sets can be performed on the same patient no sooner than every 3 months, as long as a benefit is seen. Most insurers require that you document at least a 50% improvement in the chronic migraine frequency and/or severity for continued coverage. I usually recommend that my migraine patients have a second set of injections before deciding that this treatment modality is of no benefit to them.
In clinical trials, 30.6% of patients (33/108) who were not using clean intermittent catheterization (CIC) prior to injection, required catheterization for urinary retention following treatment with BOTOX® 200 Units as compared to 6.7% of patients (7/104) treated with placebo. The median duration of post-injection catheterization for these patients treated with BOTOX® 200 Units (n = 33) was 289 days (minimum 1 day to maximum 530 days) as compared to a median duration of 358 days (minimum 2 days to maximum 379 days) for patients receiving placebo (n = 7).
