Blepharoptosis is due to the dispersion of the botulinum toxin through the fascia of the orbital septum to the levator muscle of the upper eyelid in the upper eyelid and is related to the application of botulinum toxin outside the safe area or to a marked dispersion of the toxin due to excessive manipulation of the region. Pyridostigmine is a reversible acetylcholinesterase inhibitor used in the treatment of myasthenia gravis and has been used for the reversal of NMJ blockade. The wrong introduction of botox in the forehead commonly results with an eyebrow raised higher than the other if both were raised by a patient.

It also has a direct cholinomimetic effect on skeletal muscle and possibly on autonomic ganglion cells and neurons of the CNS. Researchers have not yet found a safe and effective drug in cases of reversion to botulinum toxin, but some studies have shown promise as in the case of covalent selenide inhibitors [15], inhibitors of the blocked voltage calcium channel [16], anti BoNT [17] and thioredoxin inhibitors reductase [18]. Aerodigestive complications from botulinum toxin injections, although rare, may be serious.
