Although it is now popular as a cosmetic treatment to lessen lines and wrinkles, botulinum toxin has actually been used as a treatment for neurologic and ophthalmologic disorders for over 20 years. It has been shown to be both relatively safe and effective.
Is It Safe?
The FDA has approved Botox to cure migraines, involuntary muscle spasms of the eyes and limbs, urinary incontinence, and excessive sweating. Aside from curing these conditions, Botox also has a number of off-label uses.
However, these have not been evaluated and approved by the FDA. They may pose unanticipated risks to health and safety.
How Much Does It Cost?
Botox injections are less expensive than most cosmetic and medical procedures. However, Botox is not permanent.
The effects typically last for 3 to 4 months, very rarely reaching 6 months. To continue reaping the benefits, one must pay for regular treatments indefinitely, so it can still be quite costly in the long run.
