How safe is it to use Botox in the treatment of excessive sweating?
Botox is very safe. For the treatment of excessive underarm sweating, the only drug-related side effect is a perceived increase in sweating in other parts of the body, which happens in only 4.5% of cases. Botox has been used for many years to treat other diseases. It is approved by Health Canada to treat muscle spasms affecting the eyes, neck and limbs. Botox is also used to relieve muscle spasms in children as young as two with cerebral palsy. The long-term safety of the drug is well proven.
