Some primary care physicians or general practitioners are familiar with the initial treatment of focal hyperhidrosis, which may include:
Over-the-counter (OTC) antiperspirants: These can be applied to the hands and feet, as well as the armpits. Hyperhidrosis that's controllable by OTC treatment doesn't need a doctor's visit. Antiperspirants can even be used at bedtime.
Prescription antiperspirants: Most people with hyperhidrosis will sweat through OTC antiperspirants. A doctor can prescribe a higher-strength, aluminum salt-based antiperspirant. This can be effective for mild cases of excessive sweating.
