Infections often go away on their own or after treatment with antibiotics and may have no long-term effects. Excessive sweating itself is not contagious and poses no risk to others. If the cause of the sweating is an infection, the infection can be contagious. People need to increase their fluid and salt intake when they have excessive sweating. The fluid and salt may need to be given through a tube in the veins in severe cases or if persons cannot drink fluids on their own.
Side effects depend on the treatments used.
All medications have possible side effects. For example, antibiotics may cause allergic reactions and stomach upset. Specific side effects depend on the medications used. Surgery carries a risk of bleeding and infection. What happens after treatment depends on what is causing the excessive sweating.
