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
Botulinum toxins like Botox temporarily block nerve signals to muscles. As a result, injected muscles can’t contract (tense). They become weak or paralyzed. These effects can last for several months
The most commonly reported events were pain (9.3%), swelling (6.4%), and eyelid/brow ptosis (6.1%). Serious outcomes occurred in 13.5% of patients.
