What are the risks of botulinum toxin injections?

You may resume normal activities immediately.

One note of caution: Don't rub or massage the treated areas after the wrinkle treatment because it can cause the botulinum toxin to migrate to another area of your face. If this happens, you could have temporary facial weakness or drooping.

Although generally safe, botulinum toxin side effects and complications can include:

• Bruising and pain at the injection site
• Flu-like symptoms
• Headache
• Nausea
• Redness
• Temporary facial weakness or drooping

It is very unlikely that the toxin might spread beyond the treatment area, causing botulism-like signs and symptoms such as breathing problems, trouble swallowing, muscle weakness and slurred speech.
