BOTOX for migraines is an innovative, FDA-approved procedure. BOTOX is a unique approach to migraine relief that is proving to be highly effective for many patients living with the condition. Rather than reducing the symptoms of an existing headache, BOTOX works to prevent future headaches, and helps avoid the continued use of powerful prescription pain medications.
The safe and effective use of BOTOX depends upon proper storage of the product, selection of the correct dose, and proper reconstitution and administration techniques. An understanding of standard electromyographic techniques is also required for treatment of strabismus, upper or lower limb spasticity, and may be useful for the treatment of cervical dystonia. Physicians administering BOTOX must understand the relevant neuromuscular and structural anatomy of the area involved and any alterations to the anatomy due to prior surgical procedures and disease, especially when injecting near the lungs.
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. 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.
In the first study, researchers examined a sample of healthy subjects and patients with a diagnosis of migraine -any frequency-, and analysed the presence of trigger points and their location, many of the explorations resulting in a migraine crisis. The most interesting findings of this study were: 95% of migraine sufferers have trigger points, while only 25% of healty subjects have them. The most common locations of trigger points are the anterior temporal and the suboccipital region, both billateral, of the head. Furthermore, researchers found a positive correlation among the number of trigger points in a patient, the number of monthly crises and the duration in years of the condition.
Allergan PLC (AGN) is a large market cap ($65B) biopharmaceutical company with a pipeline of innovative and generic therapeutics for diseases affecting the eyes, bowel, lungs, skin, urogenital systems and brain. Through the acquisition of Tobira Pharmaceuticals and its assets including cenicriviroc (CVC), Allergan is one of the leaders in the clinical development of anti-NASH therapeutics (the focus of this article).
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.
It’s been a little over three weeks. The neurologist said that after two weeks, my migraines and headaches should be substantially reduced. I haven’t spoken about it much even to people close to me because I didn’t want to jinx it, but right around the two-week mark, my headaches faded. I did have a migraine the day after the injections, followed by a lingering headache for about a week, but my neurologist didn’t think it was caused by the Botox. I know my body and have a feeling it was, especially because the introduction or removal of medication can exacerbate lupus symptoms and flares, so I was put on a prednisone taper just to be safe.
Costs to consider: immediate out-of-pocket costs, long-term higher cost of insurance, your time, and the pain of injections. Botox for migraine costs approximately $525 per vial (100 units) and a typical migraine dose is 155 units. Depending on what your doctor charges in addition to the Botox itself, it’ll set you back $1500 – $2300 to test it out. And then there’s the needle pain. Don’t make the mistake of going to get a Botox injection if you’re in the midst of an attack, because it’ll be more painful than ever. Better to reschedule.
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
It may be necessary for the patient to have additional procedures, such as the use of filler substances (for example, Restylane, Perlane, Juvederm, Sculptra, or Radiesse) in order to plump up the wrinkles that are now relaxed. Additionally, it may be necessary to have two or three sessions of Botox treatment for deeper wrinkles before results become optimal. The area of the crease between the eyes is a particularly ideal area for Botox use in conjunction with filler as these fixed wrinkles don't always respond optimally to Botox alone. There is some controversy about using filler in that area as it may block veins or arteries and result in loss of blood and a scar to the area. Generally, the smaller particle fillers, such as Restylane or Juvederm Ultra, are best in the area between the eyes for this reason.
Autonomic dysreflexia in patients treated for overactive bladder due to neurologic disease. Autonomic dysreflexia associated with intradetrusor injections of BOTOX® could occur in patients treated for detrusor overactivity associated with a neurologic condition and may require prompt medical therapy. In clinical trials, the incidence of autonomic dysreflexia was greater in patients treated with BOTOX® 200 Units compared with placebo (1.5% versus 0.4%, respectively).
