The initial listed doses of the reconstituted BOTOX [see Preparation And Dilution Technique] typically create paralysis of the injected muscles beginning one to two days after injection and increasing in intensity during the first week. The paralysis lasts for 2-6 weeks and gradually resolves over a similar time period. Overcorrections lasting over six months have been rare. About one half of patients will require subsequent doses because of inadequate paralytic response of the muscle to the initial dose, or because of mechanical factors such as large deviations or restrictions, or because of the lack of binocular motor fusion to stabilize the alignment .
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.
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.

Backed by over 15 years of clinical studies, BOTOX® Cosmetic is the most widely researched and studied treatment of its kind, approved for use in 96 countries. The safety and efficacy of BOTOX® Cosmetic has been described in more than 495 peer-reviewed articles in scientific and medical journals.
Unremarkable. I mean, that’s a good thing in the MRI-reading world, but I’d like to say my brain is freakin’ remarkable sometimes. Maybe I’m biased. Anyways. Shortly after those tests, the Botox arrived at the office and I was scheduled for my injections. To say I was scared is putting it lightly. Like I mentioned before, I have a complete irrational fear of new medication. Also, I didn’t want my face to look different! So I documented my wrinkles just to see how many would last (if you want, be my guest to check out my embarrassing video). I didn’t have to wait long and before I knew it, I was in a room with my mom, my boyfriend, a neurologist and three needles.
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.
Allergan says Botox is well established as a drug and that the benefits and risks of toxins are well understood. "With more than 25 years of real-world clinical experience ... approximately 3,200 articles in scientific and medical journals, marketing authorizations in more than 90 markets and many different indications, Botox and Botox Cosmetic are [among] the most widely researched medicines in the world," an Allergan rep wrote in an emailed statement.
"Botox is a toxin that is extracted from a certain bacteria. It's been used for a couple of hundred years in medicine. It was first used in neurological conditions rather than cosmetic ones. It was first approved to treat spasms of the face and eye muscles. Only later was it discovered coincidentally that it could world for cosmetic purposes, like wrinkles," he says.

Botox was introduced to the world in the late 1980s by ophthalmologists, who began using it to treat optic muscle disorders. It was approved by the Food and Drug Administration (FDA) for the treatment of moderate to severe frown lines between the eyebrows (glabellar lines) in 2002, and its popularity has soared ever since. Botox is consistently one of the top five nonsurgical cosmetic procedures performed each year.
The following adverse reactions have been identified during post-approval use of BOTOX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions include: abdominal pain; alopecia, including madarosis; anorexia; brachial plexopathy; denervation/muscle atrophy; diarrhea; hyperhidrosis; hypoacusis; hypoaesthesia; malaise; paresthesia; peripheral neuropathy; radiculopathy; erythema multiforme, dermatitis psoriasiform, and psoriasiform eruption; strabismus; tinnitus; and visual disturbances.
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.

In a double-blind, placebo-controlled, parallel group study in adult patients with detrusor overactivity associated with a neurologic condition and restrictive lung disease of neuromuscular etiology [defined as FVC 50-80% of predicted value in patients with spinal cord injury between C5 and C8, or MS] the event rate in change of Forced Vital Capacity ≥15% or ≥20% was generally greater in patients treated with BOTOX than in patients treated with placebo (see Table 6).
I was lucky. My health insurance only required me to try and fail two other less expensive migraine medications, and it didn’t dictate how long I had to try them for before giving up. Other insurers have stricter rules: Aetna, for example, requires patients to try at least three medications for at least two months each. HealthPartners also requires patients to try and fail three medications, such as beta blockers and antidepressants, without specifying for how long. (Requirements may vary by state and policy.) Because these migraine drugs are designed to treat other conditions like high blood pressure and depression, they can have serious side effects like weight gain, fatigue, and difficulty in thinking and speaking clearly.
The results showed that 34% of those who responded and tried Botox said it significantly helped them. Sixteen percent reported a slight benefit. Nine percent stated that it didn’t help at all. Eleven percent stated that they would like to try Botox but it is too expensive. About 10% said they had no plans to try Botox, and 18% said they hadn’t tried it yet.

Receiving Botox injections for migraines is a straightforward outpatient procedure. The skin in the area to be injected is cleaned. Most injections are administered in the forehead area, usually above the eyes or where “worry lines” might occur. Because this area may be sensitive or patients may be experiencing hypersensitivity to pain, a topical anesthetic may be applied before the injection.

Don’t be a pill. You're more likely to get a bruise at the site of the needle injection if you're taking aspirin or ibuprofen; these medications thin the blood and increase bleeding which causes the bruise. Skip the pills for two weeks in advance of your treatment. You should also tell your doctor -- before treatment -- about any supplements you're taking, even if they're "natural," because some (such as fish oil pills, gingko, or vitamin E) also thin blood. Your doctor may ask you not to use those supplements for two weeks before your treatment.
The median duration of response in study NDO-3, based on patient qualification for re-treatment was 362 days (52 weeks) for the BOTOX 100 Units dose group compared to 88 days (13 weeks) for placebo. To qualify for re-treatment, at least 12 weeks must have passed since the prior treatment, post-void residual urine volume must have been less than 200 mL and patients must have reported at least 2 urinary incontinence episodes over 3 days with no more than 1 incontinence -free day.
