Lid droop (ptosis) can result when Botox hits the levaror palpebrae muscle which keeps the lid open. The short term remedy for this complication is an eye drop called Iodipine. Iodipine contains apraclonicine which will work by causing Muller's muscle to contract, quickly elevating the upper eyelid. This will lift the upper lid from 2-3 mm. This effect will last about 5 hours and then should be repeated. Some people develop an allergy to this and sometimes Neo-synephrine is then utilized. Most cases of lid ptosis last about a month. However, this would depend on the concentration and amount of Botox that reached the affected muscle. Since this varies, so does the time your problem will last. You should definitely remind any other injecting physician of the problem you had so that they will be specially careful this does not happen again. It is a given that the physician who injected you will recall the untoward event. Please, do not panic as I said, and many others have said before me, this too shall pass.
