The average patient will require maintenance Dysport injections every 3 to 4 months, but this timeline can vary quite a between individuals as some patients will process the injections at a faster or slower rate. Most Dysport providers will recommend that patients wait at least 90 days between sessions even if the effects have started to wear off to allow for the neurotoxin that is injected to completely work out of the patient’s body before it is re-administered. Receiving the injections more than 3 to 4 times per year can cause patients to start to build up a tolerance to the neurotoxin, leading it to be less effective if administered too frequently.
