Mild to Moderate Dysphagia Following Very Low-dose Abobotulinumtoxin A for Platysmal Bands.

We present a case of mild to moderate dysphagia in a patient after very low doses of Abobutulinumtoxin (60 units, equivalent to 20 units of Onabotulinumtoxin using a 3:1 conversion ratio). We speculate that the adverse effects noted may be due to several possibilities, such as diffusion, injection technique, or intravascular injection. Thus, although botulinum toxin-A is generally considered a safe off-label treatment for vertical platysma bands, readers should still be aware of the possible side-effects even with low dose use, as supported by our case report of mild to moderate dysphagia with relatively conservative doses of Abobotulinumtoxin A. <p><em>J Drugs Dermatol. 2017;16(9):929-930.</em></p>.
