Abstract

Methotrexate was administered intramuscularly to ten patients with severe psoriasis and one patient with a generalized erythroderma. All patients were observed carefully for toxicity by the use of a number of laboratory procedures. Clinical improvement was compared with a control group receiving placebo injections and standard dermatologic topical therapy. The results indicate that methotrexate administered intramuscularly is a therapeutically beneficial drug; however, it is a potentially toxic drug, unless precautions are observed.
