Identifying and treating the underlying problem is the most effective way to clear up itchy skin permanently, says Cleveland Clinic. Doctors usually recommend home care measures and medications depending on the cause. Itchy skin is associated with a number of conditions such as skin disease, dry skin and pregnancy.
For mild cases, home treatment options, such as using lotions to prevent dryness, using sunscreens, taking a warm bath and using mild bath soap, can help relieve itching, says WebMD. If the itching continues, medications such as oral antihistamines, corticosteroid creams, antidepressants and calcineurin inhibitors are effective treatments, according to Mayo Clinic.
