Why did my underarm Botox wear off in 2 weeks?

Botox is commonly used to treat excessive sweating in the underarms.  The dose use and the technique to inject it can both influence the results.  Without knowing how much was used to treat you, it is impossible to know if your dose might have been too little or not.  I would contact the physician who treated you to discuss your results and see if adding more Botox might be helpful.  

Hi, thank you for your question! I would suggest following up with your certified injector if you feel as though the botox has warn off. Two things that can cause the botox to wear off quickly is high metabolism of the product which can be caused by weight loss or under-dosing. Dosing for the underarms can range from 30-60 units per armpit. I would suggest having it redone by your injector and see the duration that you obtain. I would also suggest another procedure that can be used for sweating and odor of the underarms. MiraDry is the first and only FDA-approved, non-invasive treatment to safely and effectively reduce underarm sweat and odor. Patients typically see an 80% sweat reduction, 60% odor reduction and a 50% hair reduction at 12 months. The treatment is non invasive and takes about three hours to complete. Most patients see results after one treatment, though a second may be needed to reach desired affects. The miraDry system targets and destroys sweat and odor glands in your underarm. These glands do not grow back once they are destroyed.
