In addition to glabellar lines, Botox is used to eradicate crow’s feet, frown lines, and lines and furrows in the forehead. Whereas treating crow's feet and forehead lines with Botox was for many years an off-label use, the toxin has since received FDA approval for both uses. Botox is also approved to treat a variety of medical conditions, including ocular muscle spasms, problems with eye coordination, severe armpit perspiration, migraine headaches, overactive bladder, urinary incontinence related to nerve damage from conditions such as multiple sclerosis and spine injury. Botox is being studied to determine if it might be useful in treating conditions such as knee and hip osteoarthritis, temporomandibular joint disorder (TMJ) and benign prostatic hyperplasia (BPH).
In 2005, the national average cost of a BOTOX® injection was just over $375. However, the cost of BOTOX® treatment varies from area to area. In 2005, the northeastern United States had the highest BOTOX® average cost, at just over $500, while the western states had the lowest average, at under $370. It is important to keep in mind that these statistics may be somewhat misleading, as the cost of BOTOX® injections in Los Angeles will almost certainly be higher than BOTOX® treatment price in say, a rural area of Pennsylvania.
Results will be evident within three to 10 days. Photographs may be taken before the procedure so that patients can check their results themselves rather than relying on their memory. It is surprising to see how many people do not recall how they looked before the procedure and are amazed at the difference when shown a picture. Prior to having the procedure done, the patient should realize that Botox does not actually erase lines but relaxes them. What this means is that deeper lines will become somewhat less deep and superficial lines will nearly disappear. This can be likened to the act of steaming a garment's wrinkles rather than ironing them.
Postmarketing reports indicate that the effects of BOTOX® Cosmetic and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and spasticity and at lower doses.
Marrying ophthalmology to dermatology, Jean and Alistair Carruthers observed that blepharospasm patients who received injections around the eyes and upper face also enjoyed diminished facial glabellar lines (“frown lines” between the eyebrows), thereby initiating the highly-popular cosmetic use of the toxin. Brin, and a group at Columbia University under Monte Keen made similar reports. In 2002, following clinical trials, the FDA approved Botox Cosmetic, botulinum A toxin to temporarily improve the appearance of moderate-to-severe glabellar lines. The FDA approved a fully in vitro assay for use in the stability and potency testing of Botox in response to increasing public concern that LD50 testing was required for each batch sold in the market.
