I had Xeomin Wednesday afternoon. Starting Friday, my eyes were very swollen. I am taking Benadryl. What else can I do?

It would be beneficial if you could post some pictures for review. I would recommend following up with your injector.

Thank you for your
question.If you are experiencing swollen, itchy eyes that could be a possible side effect of Xeomin, contact the provider who performed your injections for a follow up appointment to review your concerns.To be sure, see two
or more 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.

If you are having a problem shortly after undergoing injectionsI would reach out to the person who did the injections.  They should be able to address your concerns adequately.  If they are unavailable or unable to answer your questions satisfactorily than I would consider seeking a second opinion
