Dysport is an injectable protein that was approved by the FDA in April of 2009. It works much like Botox in order to relax facial wrinkles. Like Botox it can also be used to help with excessive sweating (hyperhidrosis) and muscle spasm.
Although Botox and Dysport are two different products the approximate conversion is around 2.5 units of Dysport for every one unit of Botox. If for instance you normally use 20 units of Botox to treat the wrinkles between the eyes you would need about 50 units of Dysport.
It depends on how many units you use. There are some studies that show Dysport lasting slightly longer than Botox but in most of the those studies a larger ratio than 2.5:1 (Dysport:Botox) was used. When comparing 50 units of Dysport to 20 units of Botox most studies show that their duration of effect is almost identical.
For a small percentage of patients the answer is likely yes. In studies about 35% of patients noticed that their Dysport started working within the first 48 hours.
It depends on how much you use. If you use the equivalent dosing the cost of Dysport is almost exactly the same as Botox.
Yes, Dysport has been used in Europe for many years and has an almost identical side effect profile to that of Botox.
