Botulinum Toxin Treatment of Underarm Sweating

Avoid aspirin, Vitamin E, St John’s wort and other dietary supplements.
Avoid alcohol and Ibuprofen for 2 days.
Shave underarms and do not use deodorants or antiperspirants for 24 hours before your appointment.

You may have temporary purple discolouration of the skin after treatment (because of the iodine-starch test) which will wash off over 1-2 days with regular washing.
Do not massage the treated areas or apply heat on the day of treatment.
Avoid exercise or activities that cause flushing on the day of treatment including hot tubs, sauna and tanning.
Gently apply a cool compress or wrapped ice pack to the treated areas for 15 minutes every few hours as needed to reduce discomfort, swelling or bruising up to a few days after treatment. If bruising occurs, this usually resolves within 7-10 days.
Botulinum toxin treatment usually takes 1 -2 weeks to fully develop and last approximately 6 months.
Contact the surgery if you feel that you require a touch up after 2-3 weeks.
