In order to achieve acceptable disease control, occasionally it is necessary to use more than one medication to treat psoriasis. This is known as combination therapy. Topical medications are often used in conjunction with other treatments for psoriasis, and occasionally oral or biologic medications are combined with phototherapy. Biologic drugs should not be used together. Combination therapy allows your care team to help you find the best treatment for you. However, using more than one medication to treat psoriasis can also increase the cost of treatment and the amount of effort required to follow treatment directions.
