Hyperhidrosis is known as excessive sweating beyond what is normal for cooling the body from heavy exertion or exercise. It most commonly occurs in the underarms, hands, and feet. It can cause great distress from a social and professional standpoint and interfere with normal daily life. Treatment typically consists of over the counter and prescription antiperspirants, as well as Botox injections. Botox for hyperhidrosis is safe and effective, lasting nearly 6 months in many cases.
