Dysport Overview

Reviewed: August 4, 2016

Dysport is a prescription medication used to treat muscle problems of the neck, elbows, wrists, and fingers. It is also used to treat frown lines (wrinkles) between the eyebrows.

Dysport is a toxin produced by bacteria. It belongs to a class of drugs called neurotoxins, which relax muscles by decreasing nerve signals to those muscles.

This medication comes in an injectable form and is injected into the muscle (IM) by a healthcare professional.

Common side effects include muscle weakness or pain, and stuffy or runny nose and sore throat. Dysport may cause dizziness and eye problems including blurred vision and drooping eyelids. If this happens, do not drive a motor vehicle or participate in other dangerous activities.
