How do doctors treat itching?
Doctors treat the problem that causes you to itch. Doctors may also tell you to:
Antihistamine pills can make you sleepy, particularly if you're older. Be careful about using them if you have to drive or use power tools. On the other hand, antihistamines may help you sleep at night.
You can buy some creams for itching without a prescription. But talk to your doctor before you use them. Corticosteroid creams, such as hydrocortisone, can help some kinds of itching but are bad for others (for example, itching caused by a skin infection). Antihistamine creams and skin-numbing creams that contain benzocaine sometimes cause a skin reaction, so doctors usually don't want you to use those.
