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, generalized 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.
The number of headache days determines whether the patient has episodic migraine (EM) (14 or fewer headache days a month) or CM (more than 15 days of headache a month). The best method of determining the actual number of headache days is to subtract this from the number of completely headache-free days in a month. If headache is present on more than half the days in the month, and there are migraine features on at least 8 days a month, the condition is termed CM. The migraine features only have to be present on 8 days out of the month and not on every headache day. The other headache days in this condition are considered to be milder forms of migraine, and they do not have all the typical migraine features. If headache is present on fewer than 15 days a month, this is referred to as EM. EM can transform to CM over time. If analgesics are used on 10 or more days per month, this can lead to a transformation to CM. The patient’s headache pattern over a 12-month period should be determined, and during this time, there should be at least 3 months with 15 headache days; 8 of these days should meet migraine criteria.1-3
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).
In 2016, the stock price of Tobira Pharmaceuticals stumbled on the release of the top-line data of the Phase 2b CENTAUR study of CVC therapy in NASH because the clinical trial missed its primary clinical outcome of improvement in NASH resolution without worsening of liver fibrosis. However, CVC therapy achieved its secondary clinical outcome of improvement in liver fibrosis without worsening of NASH resolution. The clinical efficacy of CVC on NASH liver fibrosis is currently being further researched in the ongoing Phase 3 AURORA clinical trial.

No definitive serious adverse event reports of distant spread of toxin effect associated with dermatologic use of BOTOX® Cosmetic at the labeled dose of 20 Units (for glabellar lines), 24 Units (for lateral canthal lines), 40 Units (for forehead lines with glabellar lines), 44 Units (for simultaneous treatment of lateral canthal lines and glabellar lines), and 64 Units (for simultaneous treatment of lateral canthal lines, glabellar lines, and forehead lines) have been reported.
As compared to standard-size injections, Baby Botox lowers the risk of your features appearing to be frozen. Take the forehead, for example: "The risk is that you weaken your frontalis muscle, which causes your eyebrows to drop," Darren Smith, a board-certified plastic surgeon in New York City, tells Allure. "If you're getting micro doses of Botox, that's a lot less likely to happen."
Tell your doctor if you received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (tell your doctor exactly which product you received); have recently received an antibiotic injection; take muscle relaxants; take allergy or cold medicines; take sleep medicine; take aspirin-like products or blood thinners.
Khalaf Bushara and David Park were the first to demonstrate a nonmuscular use of BTX-A while treating patients with hemifacial spasm in England in 1993, showing that botulinum toxin injections inhibit sweating, and so are useful in treating hyperhidrosis (excessive sweating).[85] BTX-A has since been approved for the treatment of severe primary axillary hyperhidrosis (excessive underarm sweating of unknown cause), which cannot be managed by topical agents.[11][24]
The cost for Botox may range from $125 to $400 per treatment area. Multiple areas may be treated at one time, and repeat treatments are needed every three to four months, on average. When it comes to Botox and other injectables, you get what you pay for. Buyer beware: bargain Botox may increase your risk of complications, including poor cosmetic results. If the cost is prohibitive, ask your doctor about payment plans.
Patients with smaller neck muscle mass and patients who require bilateral injections into the sternocleidomastoid muscle for the treatment of cervical dystonia have been reported to be at greater risk for dysphagia. Limiting the dose injected into the sternocleidomastoid muscle may reduce the occurrence of dysphagia. Injections into the levator scapulae may be associated wit h an increased risk of upper respiratory infection and dysphagia.
Tell your doctor if you have received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (tell your doctor exactly which product you received); have recently received an antibiotic injection; take muscle relaxants; take allergy or cold medicines; take sleep medicine; take aspirin-like products or blood thinners.
Botox essentially paralyzes the muscles and stops them from contracting. Results are visible within one week after treatment and remain for a minimum of three months. Some surgeons suggest that Zytaze, a new prescription zinc supplement, can extend these results if taken in the days leading up to your Botox injections. Ask your doctor about Zytaze before your next Botox injection.

Botox injections like other goods and services in New York City are typically more expensive then in the suburbs where the rent and salaries are also less expensive. So it is true that in general Botox cost more in NYC. In one vial of Botox there is 100 units of medicine and each unit costs on average $20. Most patients require between 20 to 60 units.That translates into an average between $400 and $1200.
In 1820, Justinus Kerner, a small-town German medical officer and romantic poet, gave the first complete description of clinical botulism based on extensive clinical observations of so-called “sausage poisoning”.[37] Following experiments on animals and on himself, he concluded that the toxin acts by interrupting signal transmission in the somatic and autonomic motor systems, without affecting sensory signals or mental functions. He observed that the toxin develops under anaerobic conditions, and can be lethal in minute doses.[38] His prescience in suggesting that the toxin might be used therapeutically earned him recognition as the pioneer of modern botulinum toxin therapy.[39]
BOTOX may be an effective treatment for those who suffer from chronic migraines. Many patients have struggled to find a treatment that truly provides relief from this debilitating condition. While there are migraine medications and a host of natural remedies, for many people, none of these methods bring real relief. BOTOX may be the option that brings the relief from pain that patients have been seeking for so long.
Chapman and Bomba-Warczak both think Botox is safe when used correctly, but they say their inboxes quickly filled with messages after their study was published. "We were startled by the number of people who feel they were harmed by these toxins," says Chapman. "We feel these were pretty safe agents. Now it seems that for some people, they believe the toxin can sometimes cause something that may be irreversible. And that's a total mystery."
The median duration of response in Study OAB-1 and OAB-2, based on patient qualification for re-treatment, was 19-24 weeks for the BOTOX 100 Unit dose group compared to 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.
Most practices have a flat cost for each injection of BOTOX® Cosmetic, though some will break it down by “units” used per treatment. Flat rates are usually somewhere between $300 and $1000, while per-unit rates are usually around $10-15 per unit. Though the BOTOX® Cosmetic price paid by physicians is normally about $400 for each vial (each vial contains 100 units, or enough for about 4 or 5 treatments), the vial must be used within a few hours of opening, so if the entire vial is not used, the physician will often have to throw the rest out.
Botox must be used only under a doctor's care. It's important that injections be placed precisely in order to avoid side effects. Botox therapy can be dangerous if it's administered incorrectly. Ask for a referral from your primary care doctor or look for a doctor who specializes in your condition and who has experience in administering Botox treatments.
Postmarketing Experience: The following adverse reactions have been identified during postapproval use of LATISSE®: dry skin of the eyelid and/or periocular area, eye swelling, eyelid edema, hypersensitivity (local allergic reactions), lacrimation increased, madarosis and trichorrhexis (temporary loss of a few eyelashes to loss of sections of eyelashes, and temporary eyelash breakage, respectively), periorbital and lid changes associated with a deepening of the eyelid sulcus, rash (including macular and erythematous), skin discoloration (periorbital), and vision blurred.
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.
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®.
The recommended dilution is 200 Units/4 mL or 100 Units/2 mL, with a final concentration of 5 Units per 0.1 mL (see Table 1). The recommended dose for treating chronic migraine is 155 Units ad ministered intramuscularly using a sterile 30-gauge, 0.5 inch needle as 0.1 mL (5 Units) injections per each site. Injections should be divided across 7 specific head/neck muscle areas as specified in the diagrams and Table 2 below. A one inch needle may be needed in the neck region for patients with thick neck muscles. With the exception of the procerus muscle, which should be injected at one site (midline), all muscles should be injected bilaterally with half the number of injection sites administered to the left, and half to the right side of the head and neck. The recommended re-treatment schedule is every 12 weeks.
Botulinum toxin exerts its effect by cleaving key proteins required for nerve activation. First, the toxin binds specifically to nerves which use the neurotransmitter acetylcholine. Once bound to the nerve terminal, the neuron takes up the toxin into a vesicle. As the vesicle moves farther into the cell, it acidifies, activating a portion of the toxin which triggers it to push across the vesicle membrane and into the cell cytoplasm.[1] Once inside the cytoplasm, the toxin cleaves SNARE proteins preventing the cell from releasing vesicles of neurotransmitter. This stops nerve signaling, leading to paralysis.[1]

BOTOX, highly diluted botulinium toxin, works to prevent migraine by blocking the release of a chemical in muscle cells that transmits the signal to contract to muscle fibers. Research into using BOTOX to treat migraines began after patients receiving it for other conditions reported improvement in their migraine symptoms. In 2010, after years of research and collecting clinical data, the FDA approved BOTOX for treating chronic migraines.


A concern of both parents and children is whether these injections will be painful. There is no pain linked to the action of the toxin itself, only with the needle injections. To lessen this problem, the skin where the injections will be done is coated with EMLA cream before the procedure . A topical coolant spray is also used right before the needle is put in. This numbs the skin. The child may still feel pressure from the needle and a dull feeling in the muscle. The fact that a child is having a procedure done and is being held in place can upset a child more than the needle going in, even more so for preschool-aged children.

But even if the laws remain unchanged, as long as off-label uses are permitted by law, expect doctors to keep pushing the boundaries of Botox's applications--sometimes in the name of medical progress and sometimes with remarkable results.Norman Rosenthal, the Maryland psychiatrist who recommended Botox for his suicidal patient, says he's seen the upside firsthand. The patient, persuaded by Rosenthal, did indeed get Botox shots on his forehead and between his brows. Days later, Rosenthal got an email from the patient. It was a thank-you note. Finally, the patient wrote, he was feeling better.
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.
