In both studies, significant improvements compared to placebo in the primary efficacy variable of change from baseline in daily frequency of urinary incontinence episodes were observed for BOTOX 100 Units at the primary time point of week 1 2. Significant improvements compared to placebo were also observed for the secondary efficacy variables of daily frequency of micturition episodes and volume voided per micturition. These primary and secondary variables are shown in Tables 19 and 20, and Figures 5 and 6.

As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibo dy) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to onabotulinumtoxinA in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.
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.
Botox prevents migraine headaches before they start, but takes time to work. “I look to the second and third treatments to maximize effects,” says Dr. Andrew Blumenfeld. “Patients see increasing benefit with an increase in the number of treatment cycles.” One treatment lasts for 10-12 weeks, and patients reported that two Botox treatments reduced the number of headache days by approximately 50%.
In study 2, 320 adults with bilateral axillary primary hyperhidrosis were randomized to receive either 50 Units of BOTOX (n=2 42) or placebo (n=78). Treatment responders were defined as subjects showing at least a 50% reduction from baseline in axillary sweating measured by gravimetric measurement at 4 weeks. At week 4 post-injection, the percentages of responders were 91% (219/242) in the BOTOX group and 36% (28/78) in the placebo group, p<0.001. The difference in percentage of responders between BOTOX and placebo was 55% (95% CI=43.3, 65.9).
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.
Individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis or neuromuscular junction disorders (e. g., myasthenia gravis or Lambert-Eaton syndrome) should be monitored when given botulinum toxin. Patients with neuromuscular 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 Dysphagia And Breathing Difficulties].
In rare cases, Botox toxin can spread to areas beyond the injection site. If this happens, you may experience muscle weakness, vision changes, difficulty swallowing, and drooping eyelids. To reduce your risk of serious side effects and complications, always make sure Botox is prescribed and administered by a trained healthcare professional who has experience in using Botox.
There have been reports following administration of BOTOX® of adverse events involving the cardiovascular system, including arrhythmia and myocardial infarction, some with fatal outcomes. Some of these patients had risk factors including pre-existing cardiovascular disease. Use caution when administering to patients with pre-existing cardiovascular disease.
Although one cannot predict exactly who will respond, I find that those patients who are going to respond will note some improvement in headaches following the first set of injections. Repeat injection sets can be performed on the same patient no sooner than every 3 months, as long as a benefit is seen. Most insurers require that you document at least a 50% improvement in the chronic migraine frequency and/or severity for continued coverage. I usually recommend that my migraine patients have a second set of injections before deciding that this treatment modality is of no benefit to them.
Study responders were defined as patients who showed at least a 2-grade improvement from baseline value on the HDSS 4 weeks after both of the first two treatment sessions or had a sustained response after their first treatment session and did not receive re-treatment during the study. Spontaneous resting axillary sweat production was assessed by weighing a filter paper held in the axilla ov er a period of 5 minutes (gravimetric measurement). Sweat production responders were those patients who demonstrated a reduction in axillary sweating from baseline of at least 50% at week 4.
The potency Units of BOTOX are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method [see DESCRIPTION].
Make sure your practitioner is very experienced at Botox injections and is a respected medical professional. A salon stylist, for example, is not an appropriate person to administer Botox, because he or she would not have emergency equipment or sufficient medical knowledge if something went wrong. Some disreputable people have reportedly administered injections that were over- or under-diluted with saline, as well as counterfeit solutions that didn't contain Botox at all.
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.
The median duration of response in study NDO-1 and NDO-2, based on patient qualification for re-treatment was 295-337 days (4248 weeks) for the 200 Units dose group compared to 96-127 days (13-18 weeks) for placebo. Re-treatment was based on loss of effect on incontinence episode frequency (50% of effect in Study NDO-1; 70% of effect in Study NDO-2).
Most doctors suggest focusing on the quality of the skin with a proper regimen that includes daily exfoliation and SPF protection, as well regular chemical peels or specialized treatments such as Clear and Brilliant laser resurfacing during this decade. Still, there are exceptions. If constant eyebrow furrowing has resulted in the first signs of an angry crease or premature crow’s feet due to naturally thin skin are a persistent cause of frustration, injectibles can help. But as any good dermatologist will note, there is a caveat: When it comes to Botox and filler, there's a fine line between targeted tweaks and doing too much too soon. Here, in-demand experts share their guidelines for women in their 20s.
Botox is a neurotoxin derived from the bacterium Clostridium botulinum. Ingested in contaminated food, it can interfere with key muscles in the body, causing paralysis and even death. But when injected in tiny doses into targeted areas, it can block signals between nerves and muscles, causing the muscles to relax. That's how it smooths wrinkles: when you immobilize the muscles that surround fine lines, those lines are less likely to move--making them less noticeable. It's also why it's FDA-approved to treat an overactive bladder: Botox can prevent involuntary muscle contractions that can cause people to feel like they have to pee even when they don't.
For blepharospasm, reconstituted BOTOX is injected using a sterile, 27-30 gauge needle without electromyographic guidance. The initial recommended dose is 1.25 Units-2.5 Units (0.05 mL to 0.1 mL volume at each site) injected into the medial and lateral pre tarsal orbicularis oculi of the upper lid and into the lateral pre-tarsal orbicularis oculi of the lower lid. Avoiding injection near the levator palpebrae superioris may reduce the complication of ptosis. Avoiding medial lower lid injections, and thereby reducin g diffusion into the inferior oblique, may reduce the complication of diplopia. Ecchymosis occurs easily in the soft eyelid tissues. This can be prevented by applying pressure at the injection site immediately after the injection.
On November 23, 2015, Allergan and Pfizer announced their intention to merge in a $160 billion transaction, the largest pharmaceutical deal and the third largest merger in history. On April 5, 2016, after the Obama administration announced its plan to ban tax inversions, Pfizer terminated the acquisition and paid Allergan a $150 million breakup fee.
Both Aetna and HealthPartners tell The Verge in an email that they don’t require patients to try verapamil specifically. “Verapamil is just one of many options available to treat migraines. Some are FDA-approved, others are not,” says Becca Johnson, a spokesperson for HealthPartners. Patients are required to try other oral medications because they’re either cheaper or not as invasive as getting Botox injections. “The rationale is that these medications are generally effective and safe,” says Ethan Slavin, a spokesperson for Aetna.
In 1986, Oculinum Inc, Scott's micromanufacturer and distributor of botulinum toxin, was unable to obtain product liability insurance, and could no longer supply the drug. As supplies became exhausted, patients who had come to rely on periodic injections became desperate. For 4 months, as liability issues were resolved, American blepharospasm patients traveled to Canadian eye centers for their injections.
The range of prices for a single unit of Botox range between $10 and $20 per unit. But the total cost of Botox treatment depends on exactly what you're trying to achieve. For example, the cost of treating horizontal forehead lines may range anywhere from $300 to $700 depending on the factors mentioned above. For other facial areas you may need fewer units.
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).
There’s a wide variety of factors that influence the total cost: the number of units required to effectively limit facial movement in the forehead, the areas in the upper face you wish to treat, the experience level of your injector, and finally, the location of the clinic where you undergo the procedure. Botox is usually charged per unit, with a unit priced from $10 to $20. The final price can also be determined per area treated, with the forehead and frown lines charged as two seperate areas.
As a plastic surgeon, it will never be a major source of income for me, so I choose to make it easy and affordable. We charge $13 per Botox unit. Having said that, though, we have a monthly day of beauty when Botox, facials, and peels are discounted - in the case of Botox, usually to $10 per unit. Currently, because we are welcoming a Nurse Practitioner to our Aesthetic Surgery Center, we are even offering Botox for $7 per unit!
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.”
Most insurance providers now recognize BOTOX as treatment for migraines. Some have specific criteria that patients must meet, or require documentation that you have gone through other treatment protocols before trying BOTOX. It can take several weeks to receive authorization to begin treatment. Check with your insurance provider to make sure you fulfill their requirements, and to begin the approval process.
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.
Food-borne botulism results, indirectly, from ingestion of food contaminated with Clostridium spores, where exposure to an anaerobic environment allows the spores to germinate, after which the bacteria can multiply and produce toxin. Critically, it is ingestion of toxin rather than spores or vegetative bacteria that causes botulism. Botulism is nevertheless known to be transmitted through canned foods not cooked correctly before canning or after can opening, and so is preventable. Infant botulism cases arise chiefly as a result of environmental exposure and are therefore more difficult to prevent. Infant botulism arising from consumption of honey can be prevented by eliminating honey from diets of children less than 12 months old.
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.
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.
But for some conditions, step therapy can be downright harmful. In a 2016 op-ed in The Boston Globe, a patient with ulcerative colitis wrote that his health insurance forced him to try a cheaper treatment for six months, instead of the pricier meds his doctor wanted to prescribe. In those six months, his colon deteriorated so badly it had to be removed.
Extraocular muscles adjacent to the injection site can be affected, causing vertical deviation, especially with higher do ses of BOTOX. The incidence rates of these adverse effects in 2058 adults who received a total of 3650 injections for horizontal strabismus was 17%. The incidence of ptosis has been reported to be dependent on the location of the injected muscles, 1% after inferior rectus injections, 16% after horizontal rectus injections and 38% after superior rectus injections.
In this study the median total BOTOX dose in patients randomized to receive BOTOX (N=88) was 236 Units, with 25th to 75th percentile ranges of 198 Units to 300 Units. Of these 88 patients, most received injections to 3 or 4 muscles; 38 received in jections to 3 muscles, 28 to 4 muscles, 5 to 5 muscles, and 5 to 2 muscles. The dose was divided amongst the affected muscles in quantities shown in Table 36. The total dose and muscles selected were tailored to meet individual patient needs.
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:
