In double-blind, placebo-controlled chronic migraine efficacy trials (Study 1 and Study 2), the discontinuation rate was 12% in the BOTOX treated group and 10% in the placebo-treated group. Discontinuations due to an adverse event were 4% in the BOTOX group and 1% in the placebo group. The most frequent adverse events leading to discontinuation in the BOTOX group were neck pain, headache, worsening migraine, muscular weakness and eyelid ptosis.
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.
Still, there have been enough concerns that the FDA instituted a REMS (Risk Evaluation and Mitigation Strategy) requirement for all botulinum toxin preparations that specifically addresses the issues of distant spread of the toxin and the risk of problems, leading to death, from swallowing or breathing issues in certain patients who may be susceptible after botulinum toxin treatment. All products, including Dysport, Myobloc, Xeomin, and Botox, are monitored via this strategy. This is specifically aimed at a certain population of patients receiving more than the usual doses of botulinum toxin and not aimed at the casual user of Botox, per se.
“ARMR is a longitudinal study. We’re collecting data over time, which will allow us to study changes in headache patterns, health care resource utilization, diagnostic and management strategies, development of co-morbidities and responses to therapies,” Dr. Schwedt says. The registry is comprised of multiple components: The first component is an online platform in which participants fill out a baseline and follow-up questionnaires and clinicians enter the participants’ headache diagnoses. There is also an ARMR headache diary mobile app in which participants share daily information about their migraine attacks, their level of function and their treatment, if any. The third component is a blood sample, which is processed and stored in the ARMR biobank and will be used for genetic analyses. Brain imaging data are collected in the ARMR Neuroimaging Repository, and electronic health record data are pulled and confidentially entered into a centralized ARMR database. “Oftentimes, research is done in silos,” Dr. Schwedt says. “So a group at one institution is doing their own work, collecting their own data, doing their own analysis. And a group at another institution is doing their own work. That isn’t the most efficient way to move forward in the field. We believe creating and sharing data from this large and comprehensive study is really going to improve the efficiency of research in the field.”

In both studies, significant improvements compared to placebo in the primary efficacy variable of change from baseline in wee kly frequency of incontinence episodes were observed for BOTOX (200 Units) at the primary efficacy time point at week 6. Increases in maximum cystometric capacity and reductions in maximum detrusor pressure during the first involuntary detrusor contraction we re also observed. These primary and secondary endpoints are shown in Tables 21 and 22, and Figures 7 and 8.

The potency Units of BOTOX® are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, Units of biological activity of BOTOX® cannot be compared to nor converted into Units of any other botulinum toxin products assessed with any other specific assay method.
With regard to detection, current protocols using NBC detection equipment (such as M-8 paper or the ICAM) will not indicate a "positive" when samples containing botulinum toxin are tested.[citation needed] To confirm a diagnosis of botulinum toxin poisoning, therapeutically or to provide evidence in death investigations, botulinum toxin may be quantitated by immunoassay of human biological fluids; serum levels of 12–24 mouse LD50 units per milliliter have been detected in poisoned patients.[63]

I would caution against shopping around for cheap Botox. There are practitioners than offer bargain prices that are not sustainable from a business standpoint. They may be diluting their Botox or injecting less units than advertised.  Also, some practitioners charge less per unit of Botox but inject significantly more Botox than is required to achieve the optimal outcome. For instance, 60 units of Botox at $10/unit is more expensive than 45 well placed units at $12/unit. 


For most of our guests, the effects of the treatment can last anywhere from 3-6 months. Many factors can influence how long the effects last. As the product wears off, muscle action returns gradually, & the previously treated lines & wrinkles may begin to reappear, and need to be treated again. With repeated treatment, the lines and wrinkles often appear less severe than before, as the muscles are being trained to relax.Some of these factors that may shorten or lengthen the effects include:


I’ve had migraines since I was 12, but in 2015 my attacks got much worse. Without migraine-specific painkillers, my migraines make me queasy and tired, forcing me to go to bed with a freezing wet towel on my head. For the last two years, I’ve tried different medications, switched birth control pills, made lifestyle changes (less stress, more swimming, no alcohol) — to little avail. My migraines would improve for a while, but then they came back, worse than ever. Then this year, I finally discovered a treatment that works — Botox.
When BOTOX (4, 8, or 16 Units/kg) was administered intramuscularly to pregnant mice or rats two times during the period of organogenesis (on gestation days 5 and 13), reductions in fetal body weight and decreased fetal skeletal ossification were ob served at the two highest doses. The no-effect dose for developmental toxicity in these studies (4 Units/kg) is approximately equal to the human dose of 400 Units, on a body weight basis (Units/kg).

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 effects of Botox injections are neck pain and stiffness at the injection site. You may develop a headache afterward. You may also experience temporary muscle weakness in your neck and upper shoulders. This can make it hard to keep your head upright. When these side effects occur, they usually resolve on their own within a few days.

The median duration of response in study NDO-1 and NDO-2, based on patient qualification for re-treatment was 295-337 days (4248 weeks) for the 200 Units dose group compared to 96-127 days (13-18 weeks) for placebo. Re-treatment was based on loss of effect on incontinence episode frequency (50% of effect in Study NDO-1; 70% of effect in Study NDO-2).
I’ve been getting injections for migraine and cervical dystonia for a couple of years. Thank GAWD for Medicaid to cover it. I went 2 days ago for my 12 week appt. The relief was instantaneous. I’ve been under an immense amount of stress due to losing my only child 5 months ago. I’m still alive and virtually headache free. Botulism…who knew?! But…THANK YOU♡

Why Botox works isn’t completely clear. There’s some evidence that it may reduce the production of neurotransmitters related to pain in the areas where it’s injected. There’s also some evidence that it may have a broader effect on the brain’s pain centers, reducing the sensitivity that causes migraine sufferers to react to migraine triggers. While the exact mechanisms are poorly understood, the studies, as well as many of my patients’ experiences, do show a real benefit for many people.

Study 4 included 170 patients (87 BOTOX and 83 placebo) with upper limb spasticity who were at least 6 months post-stroke. In Study 4, patients received 20 Units of BOTOX into the adductor pollicis and flexor pollicis longus (total BOTOX dose =40 Units in thumb muscles) or placebo (see Table 30). Study 5 included 109 patients with upper limb spasticity who were at least 6 months post-stroke. In Study 5, patients received 15 Units (low dose) or 20 Units (high dose) of BOTOX into the adductor pollicis and flexor pollicis longus under EMG guidance (total BOTOX low dose =30 Units, total BOTOX high dose =40 Units), or placebo (see Table 30). The duration of follow-up in Study 4 and Study 5 was 12 weeks.

"For a senior leadership team that has presided over significant value destruction due in no small part to a series of poorly thought out transactions and unforced errors, entrusting the same leadership team with the task of driving value recovery via further M&A is hardly confidence inspiring in our view, to say nothing of the message it sends to shareholders regarding accountability (or more notably lack thereof)," Piper Jaffray analyst David Amsellem wrote in a note on Wednesday.
Postmarketing reports indicate that the effects of BOTOX and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, general ized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and spasticity and at lower doses.

So people told me I looked tired, overlooking the grape-size purple bruise smack dab in the center of my forehead. As one RealSelf reviewer wrote: “My head feels too tight, my eyebrow position has dropped enough to lose my nice pretty arch and my eyelids seem hooded. My eyes look smaller.” Now, if it works, looking a bit tired is a small price to pay for a few more days each month of migraine freedom and function. And bruises can be covered with makeup.
Botox gained popularity and notoriety as a wrinkle reducer in the late 1990s and early 2000s. But it wasn’t long before researchers recognized the potential of Botox for treating medical conditions, too. Today it’s used to treat problems such as repetitive neck spasms, eye twitching, and overactive bladder. In 2010, the FDA approved Botox as a preventive treatment option for chronic migraines.

In two double-blind, placebo-controlled trials in patients with detrusor overactivity associated with a neurologic condition (NDO-1 and NDO-2), the proportion of subjects who were not using clean intermittent catheterization (CIC) prior to inject ion and who subsequently required catheterization for urinary retention following treatment with BOTOX 200 Units or placebo is shown in Table 9. The duration of post-injection catheterization for those who developed urinary retention is also shown.
Currently, there are several anti-CGRP treatments undergoing clinical trials. Some of these treatments involve monoclonal antibodies, which reduce the activity of CGRP, potentially leading to fewer migraine attacks. One of these anti-CGRP monoclonal antibodies, erenumab (Aimovig™), has been approved by the Federal Drug Administration (FDA) and is now available for patients. A second agent, fremanezumab (Ajovy™), was approved in September 2018. A week later, the FDA approved galcanezumab (Emgality™), making it the third anti-CGRP treatment currently on the market. Results from the clinical trials involving anti-CGRP antibodies have shown that about 50 percent of patients will have at least a 50 percent reduction in migraine days. “If you think about someone who has 20 migraine days per month, they have a 50 percent chance of having 10 or less migraine days,” Dr. Starling says. “We think that there are even these super-responders who have a 75 percent response rate, as well as super-super-responders who actually go into remission.” The results from these clinical trials are very promising, Dr. Starling adds. “The adverse events have been very minimal and the efficacy has been very good. It’s all looking up.” Dr. Starling says that although these medications are available, what really needs to be looked at is how to make them truly accessible for patients. Erenumab can cost about $7,000 per year without insurance coverage. “Insurance coverage is very, very key for the majority of our patient population,” she says. “Because the medications just came out on the market, there are still a lot of unknowns about insurance coverage.”
The overall cost of  the injection is charged either at a flat rate or per unit. In terms of per unit, the overall cost of the treatment will depend on the total volume or a total number of units used in the procedure. But service charged at a flat rate depends on the area to be treated. The most expensive area is around the underarm for treating hyperhidrosis.

The one side effect that we most commonly see with Botox for migraine, ironically, is increased headache pain in the days immediately following the injections. Interestingly, some patients have the opposite effect, noticing immediate pain relief. That may be due to an acupuncture-like response, where poking needles into unhappy muscles actually makes them feel better.
It can also be expensive. Depending on your insurance, it can cost quite a lot of money — I've changed insurance providers since I first started, and my first provider was around $330 a month and charged me around $1,000 per Botox round (remember, that's four times a year). My new plan is much more expensive, around $600 a month, but the Botox copay is only $30 each time, so even if Botox is the only medical procedure I need to have done in the year, it made sense to switch.

Remember that the skill of the injector is extremely important when considering Botox injections. Because Botox can have some very obvious and embarrassing side effects like drooping eyelids, blurry vision, and excessive bruising around the injection site, it's important to consult with an experienced injector. Unlike dermal fillers which can be melted away with a follow-up injection of hyaluronidase, there's not much you can do about a bad Botox experience other than wait it out.


Recently, there has been an emerging trend of “BOTOX® Cosmetic parties,” in which several people gather at a physician’s house or another location to have BOTOX® Cosmetic injections at a lower cost. While prices for treatment may be somewhat lower at a BOTOX® Cosmetic party than for treatment administered during a normal office visit, the situation may not be ideal. The American Academy of Dermatology and the American Society of Aesthetic Plastic Surgery have both issued warnings against such “parties,” as they have reservations about the ability of the physician to provide a safe and sterile environment outside of their office.
Botox has not been approved for any pediatric use.[30] It has, however, been used off-label by physicians for several conditions. including spastic conditions in pediatric patients with cerebral palsy, a therapeutic course that has resulted in patient deaths.[30] In the case of treatment of infantile esotropia in patients younger than 12 years of age, several studies have yielded differing results.[21][better source needed]

BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. It is not known whether BOTOX® is safe or effective for severe sweating anywhere other than your armpits. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.
