By Mayo Clinic staffBotox injections are relatively safe when performed by an experienced doctor. But side effects and complications can occur. These include:
- Pain and bruising at the injection site
- Redness
- Headache
- Flu-like symptoms
- Nausea
- Temporary facial weakness or drooping
- Spread of the toxin beyond the treatment area, which can cause botulism-like signs and symptoms (trouble swallowing, muscle weakness, slurred speech and breathing problems)
Select your doctor carefully
Botox must only be used under a doctor's care. It can be dangerous if it's administered incorrectly. Look for a doctor who is board certified in dermatology; ears, nose and throat (otolaryngology); or plastic surgery. Make sure the doctor has experience with Botox treatments. A skilled and properly certified doctor can advise you on the procedure and can help determine if it best suits your needs and health.
