There are treatments available to reduce itching. Antihistamine medications such as hydroxyzine and diphenhydramine can be helpful. Another type of medication is topical corticosteroids such as hydrocortisone cream. Occasionally, oral corticosteroids such as prednisone are used for severe rashes. Other remedies such as calamine lotion are also available.
Treatment of the cause is also important, when possible. For example, antibiotics can be used to treat scabies. A thyroid hormone imbalance can often be corrected with medications. Surgery, chemotherapy, or radiation therapy may be needed to treat a tumor or cancer.
Side effects depend on the treatments used. All medications have possible side effects. For example, antihistamines can cause drowsiness or confusion.
Itching from sunburn or poison ivy will go away on its own and no further treatment is needed. Other cases may resolve with treatment, such itching caused by scabies.
Any change or response to treatment can be reported to the healthcare provider. Other monitoring is related to the cause. For example, people with thyroid hormone problems may need thyroid function tests to monitor their thyroid hormone level.
