Is chemotherapy available for severe psoriasis?
This should only be used for severe cases of psoriasis that are proven to be resistant to other treatment. Powerful drugs like methotrexate or ciclosporin are taken and combined with PUVA light treatment. PUVA involves the patient taking oral or topical agents like psoralen which enhance the effectiveness of ultraviolet light on the skin. Regular blood tests should be used to monitor possible side effects of the drugs.
