I received Dysport and 20 hours later was sick with nausea and vomiting. How long will it last?

It is extremely unlikely that Dysport has caused you to feel ill.  I suggest you visit a Dr. as it might just be coincidental and you have some other type of stomach virus. Hope you feel better and best of luck

It is unlikely that Dysport has caused your nausea and vomiting. I recommend following up with your Doctor for a formal evaluation. Best, Dr. Emer

it's extremely unlikely that 20 units of Dysport has made you sick. You should see your primary care for a full evaluation and treatment.Best wishes, Dr. Aldo

Thanks for your question- 
While many medications list a mountain of possible side effects etc, the list in reality of Dysport is very small. The difference is that Dysport is not absorbed systemically like the medications we take by mouth. This is a huge difference and likely the reason why I believe you picked up a GI bug randomly. 
I would treat this like a normal GI bug and not think that it had anything to do with your treatment. If you have any doubts or questions, please contact your injector. 
Hope this help and God Bless! 
Dr. Robb

Thank you for your question about nausea and vomiting after Dysport.I am so sorry that you have been ill.  The good news is, it is highly unlikely that Dysport is the cause of your symptoms of nausea and vomiting.  If your symptoms persist, you should likely follow up with your primary care provider or walk-in clinic.  To be sure, see two or more experienced,
licensed and board-certified providers in your area for a complete evaluation
to make sure you are a good candidate and that it is safe for you to have
treatment.
I hope this helps.
 

Nausea and vomiting are not a common side effect from Dysport. It may just be a coincidence in timing. I encourage you to visit with your primary care physician if your symptoms don't improve or worsen.

I have dysport over 15 years and have injected in approximately a thousand patient. I have never seen such a side effect. If your gastrointestinal symptoms were not incidental to receiving injection you should report to the injector to make sure reconstitution/preparation was done properly. In the mean time it you should seek symptomatic treatment and consider receiving anti histamine/steroid intakes.

As others have mentioned, it is extremely unlikely that this is related to Dysport. It is also impossible to know how long it will last, as the cause is unknown. I would recommend a visit to your PCP.
