How long does Nausea last after Botox?

As panel members indicated, reports of nausea actually related to Botox treatments is uncommon.  However, you may want to report this to your practitioner as they may want to ask you further questions or offer feedback.

In the studies the company did for the FDA, patients who were given a sugar pill (placebo) treatment, several had nausea, as did several who had the Botox.  There may be no true correlation.  I had one patient who did inform me of having nausea for a day after the botox and also felt aches. It was never confirmed that she had the flu or other condition, and it went away after a day. She has since returned, has been retreated with the same Botox number of units and had no ill effect.

First, while nausea is a reported side effect, it is a very non specific side effect.  Only a tiny percentage of individuals getting BOTOX experience this side effect.  If you are a woman, you might ask yourself if you could possibly be pregnant because this is an even more common cause of nausea.
