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.
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.
“A younger face has a heart shape, and an older face is a little more bottom-heavy and square,” says Dr. Matarasso. “But if you put toxin in both sides, you are not reducing the movement of the muscle, you are thinning the muscle out a bit. You can restore a youthful look. It’s not as dramatic or quick-acting as other areas, but it can be a nice way to improve the contour of the face.”
Recently, there has been an emerging trend of “BOTOX® Cosmetic parties,” in which several people gather at a physician’s house or another location to have BOTOX® Cosmetic injections at a lower cost. While prices for treatment may be somewhat lower at a BOTOX® Cosmetic party than for treatment administered during a normal office visit, the situation may not be ideal. The American Academy of Dermatology and the American Society of Aesthetic Plastic Surgery have both issued warnings against such “parties,” as they have reservations about the ability of the physician to provide a safe and sterile environment outside of their office.
According to the PREEMPT paradigm, one injection of 5 units of onabotulinumtoxinA into four sites (total 20 units) into the frontalis muscle is done. The injection points are located by visually drawing a line up from the medial edge of the supraorbital rim. Patients will be injected into the muscle in the upper third of the forehead at least 1 to 2 fingerbreadths above the corrugator injection site. The lateral muscle injection areas are parallel and approximately 1 fingerbreadth lateral to the medial injection site, which is roughly in line with either the midpupillary line or the lateral edge of the cornea, which is the limbus line. In cases in which I am worried about ptosis, I inject the frontalis close to the hairline. In order to reduce the risk of these unwanted effects, injections should be administered in the upper third of the forehead only. The needle should be inserted at a 45° angle superiorly. Because the frontalis is an elevator muscle, weakening can cause brow ptosis or exacerbate preexisting brow ptosis.
According to Ravitz, it's very effective among a large sampling of her patients and is usually very well tolerated. She says some of her patients find that it even eliminates the need for medication, which is a huge deal. However, she also says, "About 7 to 10 percent of my patients find that it’s not effective and they actually feel worse during that time." As with any medical procedure, everybody (and everyone's actual body) is different and will respond to treatment differently, and it's best to do a healthy amount of research and thoroughly talk to your doctor about your body and medical history before making a decision.
In just over a decade, the number of people in the U.S. receiving cosmetic botulinum toxin type A injections--mostly from Botox but also from another brand called Dysport, which commands less than 10% of the market--exploded. From 2000 to 2015, use of the toxins for wrinkles increased 759%. It became a cultural phenomenon too, spawning Botox parties, Simpsons jokes, even greeting cards. In 2008, Sex and the City character Samantha famously quipped, "I don't really believe in marriage. Now Botox, on the other hand, that works every time."
I always tell my patients that you get what you pay for. However, you need to advocate for yourself and understand what you are getting for your dollars. Ensure that your injector is experienced and properly trained; that you are getting FDA approved Botox Cosmetic from Allergan; and know how many units you receive. As well, a physician's office should maintain a medical record of your treatments so you can optimize and customize your Botox to achieve the best effect and value. Good Luck!
"I had 25 units of Botox done by Dr. Goldberg on my forehead and frown lines. Few days later I could see the result with which I was very happy! [...] I have done Botox few times before with other specialists, after which my face would resemble a doll [...] However, after procedure with Dr. Goldberg, I am still able to lift my eyebrows and frown without forming any wrinkles." – from Dinara D.'s review of Alexander Golberg Physician PC in New York.
The potency Units of BOTOX® Cosmetic 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® Cosmetic cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method.
University-based ophthalmologists in the USA and Canada further refined the use of botulinum toxin as a therapeutic agent. By 1985, a scientific protocol of injection sites and dosage had been empirically determined for treatment of blepharospasm and strabismus. Side effects in treatment of this condition were deemed to be rare, mild and treatable. The beneficial effects of the injection lasted only 4–6 months. Thus, blepharospasm patients required re-injection two or three times a year.
Botulinum toxin injections are one approach to the treatment of muscle spasticity. These injections can be given with ease and have minimal side effects. They can also be used in very focal spasticity problems that involve a few muscle groups. This treatment may not be right for some patients, such as patients with severe, widespread muscle spasticity, and patients with permanent muscle contractures that have become rigid.
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.
Each patient has their own goals for treatment of muscle spasticity made in our clinic. These goals can include decreasing pain from muscle spasms. This can be done by reducing both how often and how intense the spasms are. It can also be done by increasing the range of motion of joints to allow improved function. Improvement of range of motion can help to:
BOTOX increases the incidence of urinary tract infection [see ADVERSE REACTIONS]. Clinical trials for overactive bladder excluded patients with more than 2 UTIs in the past 6 months and those taking antibiotics chronically due to recurrent UTIs. Use of BOTOX for the treatment of overactive bladder in such patients and in patients with multiple recurrent UTIs during t reatment should only be considered when the benefit is likely to outweigh the potential risk.
"In the majority of these cases, it's the doctors at the front line who start using Botox off-label, and then we see the treatment of things we never expected the toxin to work for," says Min Dong, a researcher at Harvard Medical School who studies botulinum toxins in the lab and has no financial ties to Allergan. "I meet with physicians who are using the toxin everywhere--for diseases you would never know about."
In overactive bladder patients with analyzed specimens from the two phase 3 studies and the open-label extension study, neutralizing antibodies developed in 0 of 954 patients (0.0%) while receiving BOTOX 100 Unit doses and 3 of 260 patients (1.2%) after subsequently receiving at least one 150 Unit dose. Response to subsequent BOTOX treatment was not different following seroconversion in these three patients.
Botox should definitely last longer than a few weeks, but how much longer varies. First time Botox users, for example, might experience Botox wearing off in less than 3 months. However, as facial muscles get conditioned to Botox, results should lengthen. Botox injections around the eyes can also last shorter than 3 months. Men, on the other hand, tend to need more Botox than women. Whatever the case, Botox results should generally last around 3 months, give or take a few days.
It is not always clear what is causing chronic migraines. BOTOX is a viable option for treating migraines, and it may be the most effective treatment for you. Migraines lead to extreme pain that impacts every aspect of life, from personal to professional. Migraines are debilitating and for some who suffer from the condition, bedrest is the only option. A BOTOX treatment for migraines is a simple procedure but could vastly improve your quality of life.
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).
