After working out techniques for freeze-drying, buffering with albumin, and assuring sterility, potency, and safety, Scott applied to the FDA for investigational drug use, and began manufacturing botulinum type A neurotoxin in his San Francisco lab. He injected the first strabismus patients in 1977, reported its clinical utility in 1980, and had soon trained hundreds of ophthalmologists in EMG-guided injection of the drug he named Oculinum ("eye aligner").
"There is a difference in pricing based on the duration of the results," says L.A.-based injection specialist Lisa Goodman. (FYI: She's incredible, and I emphatically recommend seeing her if you're in L.A. or Dara Liotta, MD, if you're in NYC.) "The longer-lasting formulas cost more upfront. Shorter-term fillers can last from six to 11 months based on the patient's rate of aging (i.e., smoking, drinking, sun exposure, genetics), while the longer-term fillers last about one to two years."
In recent years, a number of high-profile lawsuits have been brought against Allergan in which plaintiffs claimed that off-label uses--for ailments including a child's cerebral-palsy symptoms, for instance, or an adult's hand tremors--resulted in lasting deleterious side effects. Still, the drug's acceptance in a growing number of doctors' offices worldwide, and its revenue growth, show no signs of slowing.
It can also be expensive. Depending on your insurance, it can cost quite a lot of money — I've changed insurance providers since I first started, and my first provider was around $330 a month and charged me around $1,000 per Botox round (remember, that's four times a year). My new plan is much more expensive, around $600 a month, but the Botox copay is only $30 each time, so even if Botox is the only medical procedure I need to have done in the year, it made sense to switch.
With abnormal joint movement and inactivity, muscles can shorten and contract. In the case of muscle spasticity, the joint and soft tissue can be normal, but with constant contraction of a muscle because of spasticity the muscle can shorten. When it can no longer stretch to allow full range of motion, a contracture can happen. Agents that lessen the spasticity of the involved muscles best prevent this type of contracture.
“I see a lot of patients who come in from sun damage, or who have creases in their foreheads, more lines around the sides of their mouths, crow's feet, and wrinkles on the side of their nose,” Shah says. “At this age, a dermatologist can inject Botox in the right places to help train a person’s face to no longer fall into that habit, which can help decrease the odds that they’ll develop permanent wrinkles in those spots later on.”
It is not known whether BOTOX® is safe or effective to treat increased stiffness in upper limb muscles other than those in the elbow, wrist, fingers, and thumb, or in lower limb muscles other than those in the ankle and toes. BOTOX® has not been shown to help people perform task-specific functions with upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles. BOTOX® is not meant to replace existing physical therapy or other rehabilitation that may have been prescribed.
