Duration of response was calculated as the number of days between injection and the date of the first visit at which patients returned to 3 or 4 on the HDSS scale. The median duration of response following the first treatment in BOTOX treated patients with either dose was 201 days. Among those who received a second BOTOX injection, the median duration of response was similar to that observed after the first treatment.
Many times, effects on spasticity are longer lasting. It is not clear if this is due to breaking down patterned movements (many muscles contracting together rather than singly) or from allowing weak muscles to get stronger over time (that were overpowered before by more spastic muscles pulling against them). It is vital to have close follow-up after the injections to figure out the best course of treatment.
The most frequently reported adverse reactions following injection of BOTOX for adult lower limb spasticity appear in Table 17. Two hundred thirty one patients enrolled in a double-blind placebo controlled study (Study 6) received 300 Units to 400 Units of BOTOX, and were compared with 233 patients who received placebo. Patients were followed for an average of 91 days after injection.
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.

"As we get older, we lose volume in our face and hyaluronic acid filler can be used as a replacement,” explains Wexler. "For younger women, injections can be used to treat areas with acne scarring or hollowness under the eyes." During your ‘20s, when the face is at its fullest and healthiest, it has been argued that a shadowy gaze can even be quite charming. But in other cases, hereditary dark circles can result in a persistently tired look, which is where a few drops of filler under the eyes may be useful. As top dermatologist David Colbert, M.D. is quick to note, however, too much Botox and filler distorts the face and as a result will make you appear older. “When the line is crossed everyone starts looking like they are related," he also cautions of a uniform cookie-cutter appearance that lacks character or individuality. Or worse. “It’s a snowball effect of people liking something, coming back too soon [for even more], and then it gets too heavy,” adds Wexler.
"Neurotoxins and facial fillers are my most popular injectable treatments," notes Zeichner. "Neurotoxins like Botox and Dysport relax muscles under the skin that can lead to folding and lines, specifically frown lines between the eyebrows. Facial fillers are my favorite cosmetic procedure in the office—there's really an art to it. I exclusively use hyaluronic acid fillers because they are safe and long-lasting."
Risks are very minor with this procedure. The main risks consist of headache, pain, and flu-like illness. In rare cases, there may be a drooping lid or eyebrow area. It is important for the cosmetic surgeon to assess the patient's lids before injecting because the patient may not be a good candidate if he or she has an extremely droopy lid to begin with or one that is held up by constantly arching the lids. Ptosis (a severe drooping of the eyelid) can occur in up to 5% of patients but is very rare if the cosmetic surgeon does this procedure often. These complications are typically very minor occurrences and resolve with time.
Baby Botox can also be used as an upkeep strategy. "I really think of it as small maintenance doses of Botox over time instead of standard doses given at three- to six-month intervals," says Smith. "The other term that describes this well is 'tweakment' — subtle changes done over a longer period of time using lower doses of product at each treatment."
Intradetrusor injection of BOTOX is contraindicated in patients with overactive bladder or detrusor overactivity associated with a neurologic condition who have a urinary tract infection. Intradetrusor injection of BOTOX is also contraindicated in patients with urinary retention and in patients with post-void residual (PVR) urine volume >200 mL, who are not routinely performing clean intermittent self-catheterization (CIC).
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.
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.
BOTOX blocks neuromuscular transmission by binding to acceptor sites on motor or sympathetic nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine. This inhibition occurs as the neurotoxin cleaves SNAP -25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within nerve endings. When injected intramuscularly at therapeutic doses, BOTOX produces partial chemical denervation of the muscle resulting in a localized reduction in muscle act ivity. In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by BOTOX.
Ratings on RealSelf.com (www.RealSelf.com) show a satisfaction rate of 65% for Botox, which is on par with other treatments such as Restylane, Juvederm, and Perlane and slightly higher than Xeomin and Dysport. Longer-term treatments, such as Ultherapy facial tightening and Liposuction/SmartLipo achieve ratings in the 80% and above area, while others such as CoolSculpting (Zeltiq) achieve ratings in the 70% area. This may reflect upon the short-term nature of all botulinum toxins versus the longer-term nature of these other procedures.
