With Botox procedures there is always the risk of side effects occurring. Some might be minor and temporary but others can be more serious. Possible side effects include:

  • An increase in sweating in parts of the body other than the area treated with Botox.
  • Soreness at the injection site. This is the most common side effect and should alleviate within a few hours.
  • Pain during the treatment. Many people have said that the treatment itself is very painful to undergo.
  • Temporary muscle paralysis.
  • Flu-like symptoms such as a headache, fever, fatigue, sore throat etc.
  • If having Botox in the palms of the hands, it can cause mild and temporary weakness and intense pain during the procedure.
  • Anxiety
  • Mild dry mouth
  • Mild bruising or haemorrhaging at the site of injection. This is usually reversible.
  • Severe allergic reactions (uncommon)

Rarely, some patients might complain of respiratory problems after Botox treatment, but this is likely to be a result of neglecting to tell the clinician of any underlying health problems before going ahead with the treatment. 

Occasionally, there is a risk of a small amount of Botox leaking out from the injection site into a nearby nerve that supplies the muscle. This will cause muscle weakness, but it is usually only minor and temporary.
