Using Dysport for Facial Lines
Dysport is approved to temporarily reduce the appearance of "frown lines" between the eyebrows in people 65 years old or younger. It is not approved for older individuals, as studies have suggested that the drug is less effective in this age group. The beneficial effects of Dysport for frown lines between the eyebrows last about three to four months. In order to maintain the effects, you will need to receive injections periodically.
Dysport Uses for Muscle Spasms
Dysport is also licensed to treat cervical dystonia, a condition that involves unusual muscle spasms or contractions
in the head or neck. Frequently, cervical dystonia causes an abnormal head position (often twisted to one side), abnormal head or neck movements, and neck pain. Dysport can help decrease the severity of the abnormal head position and can help relieve neck pain.
Although the drug will usually cause some improvement immediately, the full effects may take two to four weeks to develop and last for about three months.
How Does Dysport Work?
Dysport contains a toxin produced by Clostridium botulinum
bacteria. The drug works by decreasing nerve signals that are sent to muscles, which causes the muscles to relax. Dysport enters nerve cells and inhibits the release of acetylcholine, a chemical that transmits signals from nerve to nerve. The actions of the drug are not permanent, and the muscle will eventually recover and return to its previous state.
