Dr. Thomas Namey answered

Specializes in Rheumatology

Many uses!: Injectable mtx is used in many autoimmune diseases with great effect. The drug is given IV in high doses to treat cancer. In much lower doses, given subcutaneously like insulin, with fewer side-effects than the same oral dose, does not go to the liver. And you absorb 100%, not the 40-90% when taken by mouth. Great drug.
