Serious and/or immediate hypersensitivity reactions have been reported. These reactions include anaphylaxis, serum sickness, urticaria, soft tissue edema, and dyspnea. If such a reaction occurs, further injection of BOTOX should be discontinued and appropriate medical therapy immediately instituted. One fatal case of anaphylaxis has been reported in which lidocaine was us ed as the diluent, and consequently the causal agent cannot be reliably determined.
An injection of BOTOX is prepared by drawing into an appropriately sized sterile syringe an amount of the properly reconstituted toxin slightly greater than the intended dose. Air bubbles in the syringe barrel are expelled and the syringe is attached to an appropriate injection needle. Patency of the needle should be confirmed. A new, sterile needle and syringe should be used to enter the vial on each occasion for removal of BOTOX.

Baby Botox can be used pretty much anywhere on your face, but it's best to create subtle changes or to erase fine lines. "Something like this is especially nice for an area like the crow's feet, which is a very delicate area where a subtle treatment is more effective," explains Smith. "If someone has very deep folds, micro Botox probably isn't going to cut it. I would offer this to someone with moderate to fine lines."
Ophthalmologists specializing in eye muscle disorders (strabismus) had developed the method of EMG-guided injection (using the electromyogram, the electrical signal from an activated muscle, to guide injection) of local anesthetics as a diagnostic technique for evaluating an individual muscle’s contribution to an eye movement.[44] Because strabismus surgery frequently needed repeating, a search was undertaken for non-surgical, injection treatments using various anesthetics, alcohols, enzymes, enzyme blockers, and snake neurotoxins. Finally, inspired by Daniel Drachman’s work with chicks at Johns Hopkins,[45] Alan B Scott and colleagues injected botulinum toxin into monkey extraocular muscles.[46] The result was remarkable: a few picograms induced paralysis that was confined to the target muscle, long in duration, and without side-effects.
BOTOX® increases the incidence of urinary tract infection. 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 treatment should only be considered when the benefit is likely to outweigh the potential risk.
Now, thanks in large part to off-label use, Botox--the wrinkle smoother that exploded as a cultural phenomenon and medical triumph--is increasingly being drafted for problems that go far beyond the cosmetic. The depression suffered by Rosenthal's patient is just one example on a list that includes everything from excessive sweating and neck spasms to leaky bladders, premature ejaculation, migraines, cold hands and even the dangerous cardiac condition of atrial fibrillation after heart surgery, among others. The range of conditions for which doctors are now using Botox is dizzying, reflecting the drug's unique characteristics as much as the drug industry's unique strategies for creating a blockbuster.
The ideal needle to use is a 30G or 31G, half-inch needle. Longer needles are problematic as they encourage deeper injections, which can increase the risk of muscle weakness, and most of the side effects such as neck pain stem from muscle weakness. Perseverative-free normal saline is the only diluent that should be used. There is a case study of a patient who died when onabotulinumtoxinA was mixed with a local anesthetic agent. The pivotal trial established an effective dose using 2 mL/100 units of onabotulinumtoxinA. A fact that is often overlooked is that the mean dose in the trial was 165 units. The patients all received 155 units with a fixed dose, fixed-site injection protocol, and an option of an additional 40 units to follow the pain. This resulted in a mean dose of 165 units, which is the standard that should be used to achieve the efficacy results reviewed above.
When BOTOX was administered intramuscularly to pregnant rats (0.125, 0.25, 0.5, 1, 4, or 8 Units/kg) or rabbits (0.063, 0.125 , 0.25, or 0.5 Units/kg) daily during the period of organogenesis (total of 12 doses in rats, 13 doses in rabbits), reduced fetal body weights and decreased fetal skeletal ossification were observed at the two highest doses in rats and at the highest dose in rabbit s. These doses were also associated with significant maternal toxicity, including abortions, early deliveries, and maternal death. The developmen tal no-effect doses in these studies of 1 Unit/kg in rats and 0.25 Units/kg in rabbits are less than the human dose of 400 Units, based on Units/kg.
When most people see the results of Botox, they are extremely pleased. Botox’s ability to iron out wrinkles is pretty impressive. The fine lines and wrinkles that were all you could see in the mirror appear much less severe and the overall appearance is refreshed and more relaxed and rejuvenated. Botox results typically last up to six months. Botox also acts as a preventative measure for wrinkles, as it prevents repetitive folding of the skin that come from the frequency of making expressions. By injecting Botox before wrinkles even form, you’re setting the stage for a younger look for years to come.
I increase the dose at each treatment cycle to 195 units. This is based on experience with patients with cervical dystonia, in whom higher doses result in a longer duration of effect. In addition, I transition to the next onabotulinumtoxinA treatment at 12 weeks by using occipital and trigeminal nerve blocks at 10 weeks. Most insurance companies will not cover onabotulinumtoxinA treatments earlier than 12 weeks, but in rare cases, 10-week cycles have been approved.

Breast reconstruction. Breast reconstruction includes primary reconstruction to replace breast tissue that has been removed due to cancer or trauma or that has failed to develop properly due to a severe breast abnormality. Breast reconstruction also includes revision surgery to correct or improve the result of a primary breast reconstruction surgery.
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).
