What is the Right Dosege for Lopidine for Botox-caused Drooping?

This dose would be unusually high.  

The dose for the iopodine is twice per day.

Now here is the bad news.  The initial subjective response to the iopodine predicts when the ptosis will resolve. When the drops work in the first week, it generally means that the amount of BOTOX that is weakening the muscle that raises the eyelid was small and the effect typically resolves in 4 to 6 weeks. When the drop does not improve the eyelid ptosis, it implies a more profound paralysis of this muscle. This can be associated with a much more persistent ptosis last 3 to 6 months and occasionally longer.  I would recommend assessment by an independent eyelid plastic surgeon to document your status and monitor your recovery.  And yes I would advise you to find a different doctor for future BOTOX treatments.

Iopidine 0.5% can help to improve eyelid drooping (blepharoptosis) induced by botulinum toxin A (Botox). It works by stimulating one of the muscles that lifts the eyelid (Mueller's muscle).  This medication can raise the eyelid several millimeters and it can last for a few hours.  Using Iopidine in this manner is considered an "off-label" use, meaning it is not approved by the FDA. The most common dosing is 1 or 2 drops at a time, either several times a day or just before social events. It should not really be used more than 3 times a day. 

Luckily, a droopy eyelid after Botox resolves within weeks and rarely months.
