Botulinum toxin is used to treat a number of disorders characterized by overactive muscle movement, including post-stroke spasticity, post-spinal cord injury spasticity, spasms of the head and neck,[8] eyelid,[9] vagina,[10] limbs, jaw, and vocal cords.[11] Similarly, botulinum toxin is used to relax clenching of muscles, including those of the oesophagus,[12] jaw,[13] lower urinary tract and bladder,[14] or clenching of the anus which can exacerbate anal fissure.[15] It may also be used for improper eye alignment.[16] Botulinum toxin appears to be effective for refractory overactive bladder.[17]
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.
In recent years, a number of high-profile lawsuits have been brought against Allergan in which plaintiffs claimed that off-label uses--for ailments including a child's cerebral-palsy symptoms, for instance, or an adult's hand tremors--resulted in lasting deleterious side effects. Still, the drug's acceptance in a growing number of doctors' offices worldwide, and its revenue growth, show no signs of slowing.
It's also not approved by the U.S. Food and Drug Administration (FDA) for depression, not that that stops doctors from prescribing it that way. Such off-label use of Botox, like that of any FDA-approved drug, is legal in the U.S. That's because once a drug has been approved by the FDA for a condition, licensed physicians are legally allowed to prescribe it for any medical issue they think it could benefit, regardless of whether it's been proved to work for that condition.

The safety and efficacy of onabotulinumtoxinA for CM was demonstrated in the pivotal phase III Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) trial. In this trial, patients were treated every 12 weeks whether or not their headaches had returned to baseline levels and the primary outcome period was after two treatment cycles. At baseline, these patients had more than 19 headache days, and after two treatment cycles, their headaches had been reduced by 8 to 9 days per 28 days. The responder rate analysis of the study population shows that about 25% of patients improved by 75% in terms of a reduction of migraine days. In my practice, I usually do three cycles 12 weeks apart, and only if there is no change in headache frequency after this, do I change treatments. In the pivotal trials, the first statistical separation from placebo occurred in the first 4 weeks. There is a small subgroup of patients who fail to respond to the first two treatments and only start to respond after the third treatment.4-10
Botox injections work by weakening or paralyzing certain muscles or by blocking certain nerves. The effects last about three to twelve months, depending on what you are treating. The most common side effects are pain, swelling, or bruising at the injection site. You could also have flu-like symptoms, headache, and upset stomach. Injections in the face may also cause temporary drooping eyelids. You should not use Botox if you are pregnant or breastfeeding.
Safety and effectiveness of BOTOX have not been established for the treatment of other upper or lower limb muscle groups. Safety and effectiveness of BOTOX have not been established for the treatment of spasticity in pediatric patients under age 18 years. BOTOX has not been shown to improve upper extremity functional abilities, or range of motion at a joint affected by a fixed contracture. Treatment with BOTOX is not intended to substitute for usual standard of care rehabilitation regimens.
Botox is best known for smoothing out wrinkles, but since 2010 it’s also been used to prevent migraines. (Scientists aren’t 100 percent sure why Botox works, though it may interfere with the transmission of pain signals to the brain.) Though the 36 injections I get every three months in my forehead, skull, neck, and shoulders are painful, they’ve been a game changer. I went from 16 to 18 migraines a month to about eight. The intensity of the pain has gone down, too. The results are so good that I find myself frustrated that I spent so many years in unnecessary misery.
In 1998, David E.I. Pyott became CEO of Allergan. He was enthusiastic about Botox's wrinkle-reducing potential, he says, and pushed the company to conduct a series of studies on the matter. In 2002, Botox earned FDA approval for so-called frown lines--wrinkles between eyebrows--marking the first time a pharmaceutical drug was given the green light for a strictly cosmetic purpose. In 2001, the year before Botox was approved for wrinkles, it generated about $310 million in sales. By 2013, the year it was approved for overactive bladder, Allergan reported nearly $2 billion in revenue from Botox.

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.


Over the next three decades, 1895-1925, as food canning was approaching a billion-dollar-a-year industry, botulism was becoming a public health hazard. Karl Friedrich Meyer, a prodigiously productive Swiss-American veterinary scientist created a center at the Hooper Foundation in San Francisco, where he developed techniques for growing the organism and extracting the toxin, and conversely, for preventing organism growth and toxin production, and inactivating the toxin by heating. The California canning industry was thereby preserved.
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:
In November, the FDA held a two-day hearing asking for expert comment on the agency's rules concerning off-label drug use and marketing. Some said the practice paves the way for scientific progress and gives doctors and their patients much needed alternatives for hard-to-treat medical conditions. Others said that off-label drug use is primarily financially motivated and that it poses a serious threat to public health, particularly when drugs are used experimentally on children.
A migraine requires only two of the following headache features: a unilateral distribution (one-sided), pulsatile quality (throbbing), moderate or severe pain (more than 5 out of 10), and aggravation by physical activity (such as bending over). In addition, to diagnose migraine, only one of the following is required: nausea or vomiting or sensitivity to light and noise.
Individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis (ALS), or neuromuscular junction disorders (eg, myasthenia gravis or Lambert-Eaton syndrome) should be monitored when given botulinum toxin. Patients with known or unrecognized neuromuscular disorders or neuromuscular junction disorders may be at increased risk of clinically significant effects including generalized muscle weakness, diplopia, ptosis, dysphonia, dysarthria, severe dysphagia, and respiratory compromise from therapeutic doses of BOTOX® (see Warnings and Precautions).

The idea of a needle going toward your forehead, in between your eyes, or at your eyebrows might be a little daunting, but rest assured, not only is Botox FDA-approved, but it’s a very common (and highly-requested) procedure. It’s commonly used for cosmetic reasons, but it also helps alleviate a slew of other health concerns.”Botox was first approved by the FDA in 1989 to treat blepharospasm of the eyelid, and now can treat hundreds of medical conditions, such as hyperhidrosis (excessive sweating) or chronic migraines,” dermatologist Jill S. Waibel, MD. She also notes that it was only approved for cosmetic purposes in 2002. “Since then, millions of people have had Botox done safely and effectively. It is important to remember that Botox is safest when used by a board certified dermatologist or a plastic surgeon.”
The most common severe adverse reaction associated with the use of BOTOX injection in patients with cervical dystonia is dysp hagia with about 20% of these cases also reporting dyspnea [see WARNINGS AND PRECAUTIONS]. Most dysphagia is reported as mild or moderate in severity. However, it may be associated with more severe signs and symptoms [see WARNINGS AND PRECAUTIONS].
BTX-A is now a common treatment for muscles affected by the upper motor neuron syndrome (UMNS), such as cerebral palsy, for muscles with an impaired ability to effectively lengthen. Muscles affected by UMNS frequently are limited by weakness, loss of reciprocal inhibition, decreased movement control and hypertonicity (including spasticity). In January 2014, Botulinum toxin was approved by UK's Medicines and Healthcare Products Regulatory Agency (MHRA) for the treatment of ankle disability due to lower limb spasticity associated with stroke in adults.[19] Joint motion may be restricted by severe muscle imbalance related to the syndrome, when some muscles are markedly hypertonic, and lack effective active lengthening. Injecting an overactive muscle to decrease its level of contraction can allow improved reciprocal motion, so improved ability to move and exercise.
Still, Botox's use for depression raises a question that confounds some researchers. In some cases, how Botox works is evident: the toxin can block the signals between nerves and muscles, which is why it can help calm an overactive bladder, say, or a twitching eye, or the facial muscles that make wrinkles more apparent. In other cases, however (with migraines as well as with depression), scientists are flummoxed. They may have noticed that the drug works for a given condition, but they aren't always sure why--in sciencespeak, they don't know what the mechanism is.
Botulinum toxin is a purified substance that's derived from bacteria. Injections of botulinum toxin block the nerve signals to the muscle in which it was injected. Without a signal, the muscle is not able to contract. The end result is diminished unwanted facial wrinkles or appearance. Commonly known types of botulinum toxin type A injections include Botox®, Dysport® and Xeomin®.

In a double-blind study of 123 adults with regular, chronic migraine, the adults receiving botulinum toxin type A experienced fewer migraine attacks each month. In addition, attacks they did experience were less intense, of shorter duration, and required less treatment than adults who did not receive Botox injections for migraine. These injections were also well-tolerated in adults experiencing migraine with and without aura.

Unlike a face lift or other kind of invasive facial rejuvenation procedure, treatment takes minutes and requires zero downtime. Using a very fine needle, Botox is injected into the facial muscles that are responsible for unsightly wrinkles and fine lines and relaxes the muscles. The ingredients in Botox block the signal from the nerve to the muscle, and therefore reduce it’s ability to contract, and form unsightly wrinkles.
