Dysport Injection's Side Effects

Dysport and Botox are both temporary paralyzers of muscles which work at the neuromuscular junction.  The most common side effect of both are injection site bruising.  This is incredibly rare.  Even less common is drooping (ptosis) of the upper eyelid when Dysport is injected into the glabellar region of the forehead.  Millions of injections of these botulinumtoxin A's have been injected for cosmetic purposes with minimal to no complications.

Most Common Side Effect of Dysport is Bruising

Dysport, like the other neuromodulators such as Botox, are very well tolerated overall. The most common side effect is clearly local injection site bruising. Because of the small caliber of needle that is used with these drugs, the bruising is usually quite minimal and can be covered by makeup. Filler injections cause a little more bruising due to the size of the needle used. The needles are larger because the viscosity of fillers is greater than that of botox and dysport.

One other complication that is rare but should be mentioned is ptosis or droopy lid. This is reported in the literature to be about 1 in 700. It is caused by a leakage of product away from the injection site so that it may affect the levator muscle that controls eyelid opening. If this happens, it is typically of short duration (1-2 weeks) and can be treated temporarily by prescription eye drops. Again, this is a rare complication, but needs to be mentioned for completeness.

The most common side effect of Botox or Dysport is temporary local bruising.

Both Dysport and Botox are injected into various sites, most commonly of the upper face, with very small needles. Though effort is made to inject away from small blood vessels, sometimes invisible vessels may get poked by the needle and cause a small bruise that is temporary and should resolve in 3 to 7 days. This is relatively common and though a conscientious physician injector will do her best to prevent it totally, patients should never assume one bruise-free treatment guarantees the next will be also. Don't get treatment immediately before you are being honored at an awards lunch in the next hour.

Side effects such as eyelid drooping, blurry vision, and headaches are much more rare, and generally avoided by conservative, experienced, careful physician injectors, but can still occur on occasion. Always seek a board-certified dermatologist, plastic surgeon, oculoplastic surgeon, or facial plastic surgeon (ENT) who has experience in these techniques, even if they may seem on the surface to cost more. Problems are the most costly of all.

Most Common side effect of Dysport

The most common side effects of Botox and Dysport (which are pretty much the same thing!) are bruising and the possibility of a droopy eyebrow/eyelid. Visit a well-qualified physician injector and the likelihood of either of these is much lower, as it's important to understand facial anatomy when doing injectables.

Most Common Effect of Dysport

Thank you for your question. Everyone responds differently to Dysport as far as side effects. Depending on the location of the injections, common and temporary side effects that can occur include mild discomfort at injection site, bleeding, bruising, headache, asymmetry, drooping, and heavy eyelids. Be certain to be under the supervision of a board certified dermatologist or plastic surgeon with expertise in injectables for an evaluation and for the safest and most effective treatments. I hope this helps.

Most common side effects following Dysport injections

The most common side effects I have seen from Dysport injections include minor swelling and slight bruising. In general, Dysport may result in the following issues:

1) Bruising
2) Headaches
3) Eyelid ptosis
4) An expressionless appearance - (if too much is injected, or the injections are not performed properly)
5) Minor swelling

Choosing a qualified physician who is familiar with proper technique can minimize the chances of certain side effects occurring. Duration and onset of side effects can vary from patient to patient, but generally will subside following a over a few weeks to months. Thanks and I hope this helps!
