The recommended dilution is 200 Units/2 mL, 200 Units/4 mL, 100 Units/1 mL, or 100 Units/2 mL with preservative-free 0.9% Sodium Chloride Injection, USP, depending on volume and number of injection sites desired to achieve treatment objectives (see Table 1). In general, no more than 50 Units per site should be administered using a sterile needle (e.g., 25-30 gauge) of an appropriate length. Localization of the involved muscles with electromyographic guidance may be useful.
Remember that the skill of the injector is extremely important when considering Botox injections. Because Botox can have some very obvious and embarrassing side effects like drooping eyelids, blurry vision, and excessive bruising around the injection site, it's important to consult with an experienced injector. Unlike dermal fillers which can be melted away with a follow-up injection of hyaluronidase, there's not much you can do about a bad Botox experience other than wait it out.
When my babies were little, I never discussed migraine with them. As they grew into preschool and elementary age, I found it necessary to explain it to them. They had seen me experience migraine symptoms for a long time but understood it as just being sick. We went to a migraine walk where we talked about how others cope like I do, and they heard other stories that were similar to mine. They felt empowered that we had fundraised for a disease that affects millions and that we were fighting it as a family and community. My children want to help. Having ways they can help builds their confidence in their ability to take care of me, as I do them. They know to turn the lights off, get ice and talk quietly. I have taught them how to be self-sufficient. I’m so proud of how they take care of themselves and are willing to take care of others. The qualities that they’re learning and displaying will carry them through life.
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. Once inside the cytoplasm, the toxin cleaves SNARE proteins preventing the cell from releasing vesicles of neurotransmitter. This stops nerve signaling, leading to paralysis.
Hoffman’s husband’s experience is not unusual. Once a patient gets the more expensive prescription, health insurance providers can still try and push them back to cheaper drugs. Brigham and Women’s Hospital’s Loder says that most health insurance companies stop paying for Botox if it’s not reducing a patient’s migraines by at least 50 percent. “It’s important to keep careful headache diaries and keep careful notes in order to be able to prove to the insurance company that the treatment is worth it,” Loder says. “You’re not home free once they approve it.”
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.
This imbalance can affect a joint in varied ways such as at the ankle with foot position (always points toes or up on toes when walking) or at the wrist with hand position (hand in flexion with problems grasping). After a contracture occurs (not able to bring the joint through its full range of motion, even with forceful / prolonged stretching) it can be hard to re-establish full range of motion at that joint without surgery.
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!
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®.
In 1950, pharmacist Gavin S. Herbert established Allergan Pharmaceuticals, Inc. Allergan focused on the discovery and development of novel formulations for specialty markets, as well as intimate collaboration with physicians and the scientific community. In 1953, Allergan produced eye drops and formulated new products such as the first cortisone eye drop to treat allergic inflammation and the first ophthalmic steroid decongestant.
In the case of Botox, doctors who experiment off-label say they do so because they're looking for better treatment options for their patients. "In my 30 years of medical practice, Botox is one of the most impactful treatments I had ever seen," says Dr. Linda Brubaker, dean and chief diversity officer of the Loyola University Chicago Stritch School of Medicine, who independently studied Botox for overactive bladder before the FDA approved it for that condition in 2013.
This is where Botox comes into play. When you get consistent Botox injections, you prevent potential wrinkle formations from getting deeper or worse. Botox limits the range of facial muscle movement (when done skillfully, your face will not get that frozen look) so that wrinkles don't worsen over time. If you have a bad habit of frowning or lifting your brows for no reason, consistent Botox injections can also help your face kick these bad habits and therefore prevent any potential lines from getting etched in your skin. Getting frequent Botox injections may also help relax your facial muscles so that you don't need as a high a dose or as frequent as an injection to maintain your results.
Think about it this way: people make facial expressions every single day, whether it's expressing an emotion (i.e. smiling) or simply out of habit (i.e. raising your brows). Making facial expressions causes temporary dynamic lines to show up in your face. These lines go away when your face returns to rest. However, as you continue to make facial expressions, day after day and year after year, and as your skin ages, these lines start to get etched in your skin. That's when frown lines get progressively deeper for people who frown all the time. Or when crow's feet stay put even after you stop smiling or squinting. Eventually, what once were dynamic wrinkles become wrinkles that are just there, even when you don't make any facial expressions.
So people told me I looked tired, overlooking the grape-size purple bruise smack dab in the center of my forehead. As one RealSelf reviewer wrote: “My head feels too tight, my eyebrow position has dropped enough to lose my nice pretty arch and my eyelids seem hooded. My eyes look smaller.” Now, if it works, looking a bit tired is a small price to pay for a few more days each month of migraine freedom and function. And bruises can be covered with makeup.
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 clinical trials, 30.6% of patients (33/108) who were not using clean intermittent catheterization (CIC) prior to injection, required catheterization for urinary retention following treatment with BOTOX® 200 Units as compared to 6.7% of patients (7/104) treated with placebo. The median duration of post-injection catheterization for these patients treated with BOTOX® 200 Units (n = 33) was 289 days (minimum 1 day to maximum 530 days) as compared to a median duration of 358 days (minimum 2 days to maximum 379 days) for patients receiving placebo (n = 7).
