Prescription Dysport is an injection used to temporarily improve the look of your moderate to severe frown lines without changing the look of your whole face. The untreated facial muscles still work normally, allowing you to freely show facial expressions, such as smiling, in untreated areas.
Dysport is a formulation that has been shown to deliver temporary improvement in moderate to severe frown lines, even with repeat treatments. So, the effect of repeat treatment with Dysport may be comparable to your first use.
With just 1 injection into each of 5 points between and over the eyebrows, Dysport blocks the signal from the nerve to the muscles, ultimately resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines. You should not be treated with Dysport more frequently than every 90 days.
Treatment with prescription Dysport can temporarily improve the look of your moderate to severe frown lines. Treatment generally takes just 10 to 20 minutes.
The most common side effects of Dysport treatment are nose and throat irritation, headache, injection site pain, injection site skin reaction, upper respiratory tract infection, eyelid swelling, eyelid drooping, sinus inflammation, and nausea. You should wait at least 90 days between Dysport treatments.

Tell your doctor about all the medicines you take, including prescription and nonprescription medicines, vitamins and herbal and other natural products. Using Dysport with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you have received Dysport in the past.
Especially tell your doctor if you: have received any other botulinum toxin product in the last four months, have received injections of botulinum toxin, such as Myobloc® (rimabotulinumtoxinB), Botox® (onabotulinumtoxinA), or Xeomin® (incobotulinumtoxinA) in the past (be sure your doctor knows exactly which product you received), have recently received an antibiotic by injection, take muscle relaxants, take an allergy or cold medicine, or take a sleep medicine.
