Which over-the-counter cream should I use to get rid of it?

You should use an over-the-counter cream containing cortisone or a derivative to help get rid of psoriasis. If your doctor has not prescribed anything, you can ask your pharmacist to send a request for a prescription or call your doctor directly. The most powerful over-the-counter cream available is Spectro Eczema Care, but you will need to ask for it at the counter and have it added to your medical records.
