When can I expect to get even a little relief from eyebrow ptosis? I have caveman eyebrows with no movement from Dysport.

Thank you for your question. I suggest you see your injector for an examination. It might be possible to make an adjustment on the muscles pulling the eyebrows down. Best. 

Dysport results resolve in 3-4 months. In the mean time, venus legacy and thermage treatments can soften results. See an expert. Best, Dr. Emer

However, it is possible to impose a correcting treatment about 2 months after the initial treatment.  I recommend a Microdroplet Lift® for this purpose.  This service concentrates treatment at the eyebrow to create a uniform brow softening and lift without freezing the forehead.  Look for a Microdroplet Lift injector.

I'm sorry to hear that you've had issues with your Dysport treatment. There is no way to reverse the effects of the treatment. You will gradually notice improvement over the next three to four months. I've included a video on neuromodulators that I hope you find helpful.

so sorry this happened to you! it can be very frustrating. while 25 unit to the frontalis muscle does not sound exorbitant, it really is more about where it was placed. placed too low in the forehead even 10 units can drop the brow. the good news is that it should start to wear off more quickly than the 3 months until the toxin is totally gone. in the mean time a little time. i will disagree with others - iopidine will not help a drooping brow, but it can help true eyelid ptosis from toxin. 
a little patience and make sure you give some feedback to your injector should you go back...

The dosing of 50 in the glabella and 25 in the forehead seems reasonable. Usually there will be some lessening of the effect in 3-4 weeks. There is nothing to do in the meantime.
