I got Dysport injection today for crows feet. 36 units total. I have an area that looks like a swollen vein. Should I worry?

Thank you for your question. As with any injection, there are definite risks including bruising and swelling which are the most common. Besides from that if you go to an expert Dysport injector, the chances of having an undesired outcome is very low. I would wait a week or two, and then revisit with your injector, if there are any concerns that you may have.

While there  are  side effects associated with any treatment, the relative risk of injections of dysport or similar drugs is low.  I would contact the physician who performed your injection to have your specific questions answered.

Any injections can cause swelling, bruising and pain. This can happen with dysport as well.  Compression and icing are the best options at this point, if you are concerned see your physician.  Give it a few weeks and it will improve.  Best, Dr. Emer.

I have never seen a neuromodulator cause a swollen vein. Most often this would represent a small bruise or hematoma of the orbicularis muscle which would be self limited. Cosmetic doses of Dysport, Botox or Xeomin rarely spread beyond the muscle that they are injected into. Systemic side effects typically require about 10 times the dose used for wrinkles. Definitely followup with your physician injector if you continue to be concerned. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

An enlarged vessel around the eye was probably there before. Dysport shouldn't cause an issue, even if injected into a vessel.  It might cause a bruise around a vessel.  "Horror Stories" are usually related to either a poor injector, side effects unrelated to the injection but attributed by the patient to Dysport, or use of a counterfeit drug.  Dysport is very safe and there is no sense worrying at this point.
