A double-blind, placebo-controlled study enrolled patients who had extended histories of receiving and tolerating BOTOX injections, with prior individualized adjustment of dose. The mean BOTOX dose administered to patients in this study was 236 Units (25th to 75th percentile range of 198 Units to 300 Units). The BOTOX dose was divided among the affected muscles [see Clinical Studies].
“Most people in their twenties decide to try Botox simply because they want to enhance their appearance, such as relaxing the muscles in their forehead, or because they want to keep their skin looking fresh and young,” Shah says. “Starting earlier is better than later because as the lines get more and more embedded into the skin, Botox is not as effective in eliminating the lines.”
Other treatment areas that have been proven to be useful include the scalp (for migraine headaches), neck, facial and peripheral muscles (for spasms), arm pits (to inhibit sweating), the bladder and numerous other areas. The way that Botox and Dysport work is that they temporarily inhibit muscle contraction beneath the skin. When underlying muscles are relaxed the overlying folds and wrinkles are smoothed out. These injections work only by weakening underlying muscle contraction are not facial fillers like Restylane or Juvederm. Fillers and Botox or Dysport injections are not interchangeable. These injections work only by weakening underlying muscle contraction are not facial fillers like Restylane or Juvederm. Fillers are not interchangeable with Botox or Dysport injections. Fillers replace or “fill-in” lost facial volume whereas Botox or Dysport only inhibit muscle contraction.Both treatments are in fact complimentary aesthetic injections that will relax wrinkles and folds and help you regain your youthful appearance and enhance your face.
Study 4 included 170 patients (87 BOTOX and 83 placebo) with upper limb spasticity who were at least 6 months post-stroke. In Study 4, patients received 20 Units of BOTOX into the adductor pollicis and flexor pollicis longus (total BOTOX dose =40 Units in thumb muscles) or placebo (see Table 30). Study 5 included 109 patients with upper limb spasticity who were at least 6 months post-stroke. In Study 5, patients received 15 Units (low dose) or 20 Units (high dose) of BOTOX into the adductor pollicis and flexor pollicis longus under EMG guidance (total BOTOX low dose =30 Units, total BOTOX high dose =40 Units), or placebo (see Table 30). The duration of follow-up in Study 4 and Study 5 was 12 weeks.
