After working out techniques for freeze-drying, buffering with albumin, and assuring sterility, potency, and safety, Scott applied to the FDA for investigational drug use, and began manufacturing botulinum type A neurotoxin in his San Francisco lab. He injected the first strabismus patients in 1977, reported its clinical utility in 1980, and had soon trained hundreds of ophthalmologists in EMG-guided injection of the drug he named Oculinum ("eye aligner").
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.
Calcitonin gene-related peptide (CGRP) is a neuropeptide found all over the body, says Dr. Amaal Starling, an Assistant Professor of Neurology at the Mayo Clinic in Phoenix. This neuropeptide attaches to a receptor called a CGRP receptor. CGRP and its receptor are involved in numerous bodily processes—from gastrointestinal movement to the transmission of pain. Over the past few decades, there has been increasing evidence that CGRP plays a role in both migraine and cluster headache. During a migraine attack, researchers have found increased levels of CGRP in patients’ blood and saliva. They discovered migraine medications like sumatriptan reduced levels of CGRP in patients living with migraine. They also found that patients with chronic migraine—meaning 15 or more migraine days per month, eight of which either meet criteria for migraine or are treated with migraine-specific medication—had chronically elevated levels of CGRP. In addition, recent research found that giving a patient with migraine an infusion of CGRP would lead to a migraine-like attack. “All of these studies led to the hypothesis that CGRP and its receptor play a key role in migraine, as well as in cluster headache,” Dr. Starling says.
On July 29, 2016, Food and Drug Administration (FDA), of the United States of America approved abobotulinumtoxinA for injection for the treatment of lower limb spasticity in pediatric patients two years of age and older. AbobotulinumtoxinA is the first and only FDA-approved botulinum toxin for the treatment of pediatric lower limb spasticity. In the United States of America, the FDA approves the text of the labels of prescription medicines. The FDA approves which medical conditions the drug manufacturer may sell the drug for. However, those approved by the FDA to prescribe these drugs may freely prescribe them for any condition they wish, called off-label use. Botulinum toxins have been used off-label for several pediatric conditions, including infantile esotropia.
Of 1242 overactive bladder patients in placebo-controlled clinical studies of BOTOX, 41.4% (n=514) were 65 years of age or older, and 14.7% (n=182) were 75 years of age or older. Adverse reactions of UTI and urinary retention were more common in patients 65 years of age or older in both placebo and BOTOX groups compared to younger patients (see Table 18). Otherwise, there were no overall differences in the safety profile following BOTOX treatment between patients aged 65 years and older compared to youn ger patients in these studies.
Botox has also been shown to prevent chronic migraines, but there, it's unclear exactly why Botox works. (For doctors, reaching a firm understanding of how Botox prevents migraines will be tricky, since they don't know for certain what causes the severe headaches in the first place.) "There were multiple clinical trials for migraines, and most of them failed," says Dr. Mitchell Brin, senior vice president of drug development at Allergan and chief scientific officer for Botox. "It took a long time to figure out where to inject and how much." Today people who receive Botox for migraine prevention get 31 injections in different spots on their head and neck. The effects of Botox can last about three to six months depending on the condition.
Step therapy is largely unregulated both at the state and federal level, though individual states have started to pass legislation to limit step therapy and protect patients: 19 US states, including California, Mississippi, and Illinois, have laws that require insurance companies to grant certain exemptions or to review appeals from doctors within 72 hours so patients can get a waiver. But even then, getting a waiver isn’t always easy.
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.
Potential Botox side effects include pain at the injection site, infection, inflammation, swelling, redness, bleeding and bruising. Some of these symptoms may indicate an allergic reaction; other allergy symptoms are itching, wheezing, asthma, a rash, red welts, dizziness and faintness. Tell your doctor immediately if you have any breathing issues or a faint or dizzy feeling.
As with the injection of any medication, your body's immune system can develop antibodies to the medication, which render the drug less effective or possibly cause development of an allergy to the drug. The more frequently the drug is injected or the more quantity that is injected, the higher the risk for these antibodies to be formed against the drug.
Lastly, a Botox treatment does not offer permanent results. Botox is most effective when treatments are carried out at regular intervals before the results fully wear off. On average, the results last for three to four months, although Botox metabolizes at different rates in different individuals. The first ever Botox treatment you receive may not last as long as subsequent treatments, plus you may require touch-ups two weeks after the procedure as your injector determines the right dosage for you. Over time, however, many patients notice that they can wait longer intervals between treatments as their treated facial muscles weaken.
If you think either of the FDA-approved anti-CGRP treatments might be right for you, speak with your primary health care provider, neurologist or headache specialist. If your medical provider isn’t aware of the treatments, don’t be afraid to let him or her know about them, or ask for a referral to a local neurologist or headache specialist. This is just the first step in advocating for the care that you deserve. To find a headache specialist in your area, consult our Find a Doctor tool. Dr. Starling believes that every person with migraine should be involved in advocacy, in order to bring awareness to the disease and break the stigma that surrounds it. She recommends that patients living with migraine get involved in advocacy organizations, such as our Move Against Migraine support community. You can also attend the annual Headache on the Hill event in which patients and providers go to Capitol Hill asking for more National Institutes of Health (NIH) research funding for migraine and other headache disorders. The next Headache on the Hill event is planned for February 11-12, 2019. Within the coming weeks, the American Migraine Foundation will be compiling a guide to all three anti-CGRP treatments. For additional information on anti-CGRP migraine treatment options, consult our doctor-verified resource library.
I usually keep my patients on migraine preventative medications until we have seen sufficient relief of migraine to warrant a taper to a lower dose or even an attempt at medication discontinuation. Patients are free to use their typical migraine abortive medications for breakthrough migraines. There are some patients that find that they still require their other anti-migraine medications for full migraine control.
On July 7, 2015, the company acquired the rights to the late stage CGRP migraine portfolio of Merck & Co, as well as two experimental drugs (MK-1602 and MK-8031) for an upfront payment of $250 million. On August 10, the company acquired Oculeve for $125 million. On August 31, the company acquired Naurex for an upfront payment of $560 million. On October 19, the company acquired AqueSys, developer of ocular implants that reduce intraocular pressure associated with glaucoma, for an initial payment of $300 million. On October 1, the company acquired Kythera Biopharmaceuticals, a company focused on the medical aesthetics market, for $2.1 billion. On November 4 the company announced the acquisition of Northwood Medical Innovation, developer of earFold, a medical device to correct protruding ears. On November 25, 2015, the company announced it would partner with Rugen Therapeutic to develop new therapies for autism spectrum disorder, rabies and obsessive compulsive disorder.
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.
According to the PREEMPT injection paradigm, a total of 5 units of onabotulinumtoxinA is injected into each corrugator muscle. To confirm the location of the muscle, the patient is asked to furrow the brow in order to activate the corrugator. Once the muscle has been located, the muscle should be palpated and pinched by holding it between the thumb and index finger. Five units of onabotulinumtoxinA is injected at an approximate 90° angle with the bevel of the needle pointing upward into the medial belly of the muscle. As the needle is inserted, there is skin resistance, which lessens when the muscle is penetrated. This decrease in resistance is termed a muscle pop. Once the muscle pop occurs, inject into the superficial muscle. If the injection is too far superior or above the corrugator muscle, brow ptosis can occur due to depression of the medial brow as the frontalis elevating function is lost and the corrugator depressing function remains unopposed. Whereas weakening the corrugator muscle will cause elevation of the medial eyebrow, alternatively, if the corrugator injection is done too low, then diffusion to the levator palpebral muscle could lead to lid ptosis.
In general, the initial effect of the injections is seen within three days and reaches a peak at one to two weeks post-treatment. Each treatment lasts approximately three months, following which the procedure can be repeated. At repeat treatment sessions, the dose may be increased up to two-fold if the response from the initial treatment is considered insufficient, usually defined as an effect that does not last longer than two months. However, there appears to be little benefit obtainable from injecting more than 5 Units per site. Some tolerance may be found when BOTOX is used in treating blepharospasm if treatments are given any more frequently than every three months, and is rare to have the effect be permanent.
Dr. Starling says the FDA approval indicates that the anti-CGRP treatments are ideal for individuals with episodic migraine who have four to 14 headache days per month, and people with chronic migraine who have 15 or more headache days per month. Clinical trials are also being conducted to see if anti-CGRP antibodies are effective for the treatment of cluster headache. “The initial studies have demonstrated that it’s likely effective for cluster headache patients,” Dr. Starling says. The FDA’s approval of these medications has been incredibly meaningful for the migraine community. “The migraine community is feeling like they’re relevant—that they’re being seen, heard and taken seriously,” Dr. Starling says. “There are many people who are working hard to develop more treatment options until we can address every patient who has migraine, and eventually find a cure.”
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 needle should be inserted approximately 2 mm into the detrusor, and 30 injections of 1 mL (~6.7 Units) each (total volume of 30 mL) should be spaced approximately 1 cm apart (see Figure 1). For the final injection, approximately 1 mL of sterile normal s aline should be injected so that the remaining BOTOX in the needle is delivered to the bladder. After the injections are given, the saline used for bladder wall visualization should be drained. The patient should be observed for at least 30 minutes post -injection.
Study 1 included 126 patients (64 BOTOX and 62 placebo) with upper limb spasticity (Ashworth score of at least 3 for wrist flexor tone and at least 2 for finger flexor tone) who were at least 6 months post -stroke. BOTOX (a total dose of 200 Units to 240 Units) and placebo were injected intramuscularly (IM) into the flexor digitorum profundus, flexor digito rum sublimis, flexor carpi radialis, flexor carpi ulnaris, and if necessary into the adductor pollicis and flexor pollicis longus (see Table 25). Use of an EMG/nerve stimulator was recommended to assist in proper muscle localization for injection. Patients were followed for 12 weeks.
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.
It’s not just about Botox, though. Last month, the FDA approved the first migraine-specific drug to prevent the severe headaches. Called Aimovig, the injectable med will cost $6,900 a year, according to The New York Times, plus injection fees. Because of the high costs, experts expect the new drug to be subject to step therapy policies. Stephen Silberstein, the director of the headache center at Jefferson University, told me in 2016 that he wouldn’t be surprised if insurance companies required patients to even try and fail Botox before covering the new meds (there are a few of them under development).
Good question. botox can be used to help elevate the eyebrows, which contribute to the heavy lid look. You want the "depressor muscles" of the brow weakened leaving the "elevator muscles" still functional. It will give some lift. It may not be enough depending on the severity of the heaviness to your eyelids. A board certified plastic surgeons should be able to advise you... READ MORE
Medicine to help the patient relax may be given in cases where the patient has not handled shots well in the past. If the patient has another procedure coming up, these shots can often be done at this time. Let the Rehabilitation Medicine office (513-636-7480) know if a procedure or surgery will be done in the future or if sedation is being discussed for injections in the clinic setting.
That’s enough to generate buzz on the patient forums like RealSelf among those who have tried it: “My neck is killing me” wrote one user; I’ve got “Stiffness, pain in the neck, headache and can’t look down” reported another. Like anything, results vary widely. “I have since felt nauseous and dizzy on and off every day, as well as have blurry vision.
Formation of neutralizing antibodies to botulinum toxin type A may reduce the effectiveness of BOTOX treatment by inactivating the biological activity of the toxin. The critical factors for neutralizing antibody formation have not been well characterized. The results from some studies suggest that BOTOX injections at more frequent intervals or at higher doses may lead to greater incidence of antibody formation. The potential for antibody formation may be minimized by injecting with the lowest effective dose given at the longest feasible intervals between injections.
