Antiperspirant Prevented Botox from Working for Hyperhidrosis?

As Botulinum toxin and topical antiperspirants affect the sweat release mechanism differently, there should not be a problem of using antiperspirants prior to the Botox. If one is using the starch - iodine test before injecting Botox to see where it should be injected, there might be a false negative test if there was less sweating from the use of the antiperspirants and less of the area responsible for the excessive sweating was treated. Otherwise, I would not have an explanation as to why it didn't work, unless you need more units, which some people demonstrate.

Please see your doctor for a follow up appointment.

Botox for excessive sweating works for most patients treated, and the antiperspirant shouldn't have any effect on the efficacy of the Botox treatment. Botox is injected superficially to the underarm area and reports-"81% of Botox patients notice at least a 50% reduction in axillary sweating measured at 4 weeks."

There is no data, or even anecdotal experience of antiperspirants or deodorants affecting the effect of botulinum toxin (e.g. Botox) on hyperhidrosis/excessive sweating. You may have been under dosed, and you may want to consider requesting the gold standard which is Botox, and make sure your doctor is a dermatologist.
