Do you need more units of dysport ratio to units of botox to obtain good results?

Botox Dysport Ratio

In our practice we use a ratio of 2.5-3.0 units of Dysport to Botox. Both work well and depends on the size of the muscle. We normally use the higher ratio in men.

Botox vs Dysport Units

While there is no set conversion factor, I have found that patients in my practice require approximately two and half times the units of Dysport as they do Botox.

Dysport vs. Botox

Yes, the ratio of units for Dysport versus Botox is generally 3 units of Dysport for 1 unit of Botox to give similar results.  When beginning Dysport it is helpful to go with standard doses and then you can customize it to your needs as you get further treatments.  Many patients report seeing the results of Dysport faster than Botox and that for some it lasts longer.

3:1 dysport to botox

Thank you for your question.  In our practice we use a 3:1 ratio of Dysport to Botox.  It will give you nice result when injected by an expert injector.

Botox to Dysport ratios

The actual liquid volume used is the same but the way the manufacturers determined the units within this is what makes it different. In my practice I use a 3:1 ratio, or 3 units of Dysport to 1 unit of Botox.

Neuromodulator conversion

While Botox and Dysport are both nueromodulators the dosage is not interchangeable.  The protocol is 3-1, that is 3 units of Dysport equal 1 unit of Botox.  Many will state that Dysport is cheaper but if you do the recommended conversion they really cost the same. It is always important to have a highly skilled injector doing your treatment as they will look at you and see how your muscles contract  in order to help you achieve the desired results. 

Dysport Versus Botox

Dysport and botox units are not interchangeable. Most people do 2-3 : 1 units dysport: botox.  Best, Dr. Emer.

Dysport vs. Botox Units

Hi Jen.  Originally, the manufacturer of Dysport stated that 50 units of Dysport were equivalent to 20 units of Botox.  This is the amount of product used by each company during their clinical trials for approval of the wrinkles in between the eyes (frown lines).  

When we used this 2.5:1 ratio for several months after the launch of Dysport, we were finding it to be a little short of the duration for Botox.  Since we have switched over to a 3:1 conversion ratio, we have been able to match the duration of 20 units of Botox by using 60 units of Dysport.  

Dysport also takes effect more quickly and we can use less equivalent units in the forehead because it disperses more widely.

Yes of course.

The party line is that these products are not interchangable which is also expressed as bioequivalent.  That is a technical word that has a very specific meaning.  Clinically, these products produce identical clinical effect.  From a practical stand point 2.6 to 2.8 units of Dysport seems to equal 1 unit of BOTOX.  Doctors do vary in this factor and that seems to be of no consequence.  Xeomin and BOTOX are dosed the same.

Dysport vs Botox

Hello and thank you for using

The answer is yes.  Both Botox and Dysport are Botulinum Toxin A.  That is the substance that temporarily causes muscles to be paralyzed and smooth out wrinkles.  They are formulated differently in regards to strength.  It takes more units of Dysport to attain the same effect as that of Botox.  However, Dysport is less expensive per unit than Botox.  Basically equals out in regards to total cost.  

Some physicians purchase more of one than the other and may receive a lower cost which is passed on to patients or is used for specials throughout the year that may save one some money.

Both are supposed to provide a reduction in wrinkles for around 4 months.  If the substance is diluted more than what the manufacturer suggests, the patient may not see as good of a result or it may not last as long.

Hope this helps.
