Can Botox Make You Feel Ill?

When botox was tested for FDA approval, some patients who were given placebo treatment  to compare with the real botox, also had vague flu-like symptoms. Rarely it does occur that patients having botox obtain flu-like symptoms but they disappear usually within one day. It does not appear to be an allergic reaction so it may not occur again fi you had it done.

While you might have developed a cold at the same time as getting your botox, flu-like symptoms are well reported in a small subset of patients.  If this happens again, you will have to decide if the benefit makes the treatment worth having these symptoms.

while reports suggest botox could possibly be the culprit, it's about as common as your finding $1million in your purse...could happen but highly unlikely...there's a long story about how the FDA comes up with some of the adverse effects they list in the insert but many have nothing to do with what the compound actually causes...I wouldn't worry about it in relation to the botox...sure your next session will go without a hitch...
 

Some people will experience symptoms of the flu after boots. Symptoms can include aches, headaches, weakness, and headaches. It is usually self limited to a day or two. Tylenol can help. I have had a few people experience this. It seems to be dose related, more units means more symptoms. I switched a couple clients to dysport and they had no symptoms with it. Xeomin is another option too. 

Those are not typical side effects from botox. I would check with your primary physician as the symptoms sound more linked with a flu.
