Methotrexate (MTX) is considered an anchor drug in the treatment of rheumatoid arthritis. It is also the first-line therapy in a multitude of rheumatologic conditions. Low-dose oral MTX is the preliminary modality of treatment for rheumatoid arthritis due to its affordability, favorable outcomes, and limited risks. ⋯ Although SC MTX and intramuscular MTX have similar pharmacokinetics, SC MTX may be preferred by most patients. Development of prefilled syringes and auto-injectors have enabled self-administration of the medication providing the patients with a sense of independence and improved general well-being. Hence, SC MTX can prove to be more efficacious in patients refractory to oral MTX therapy or in patients experiencing severe gastrointestinal adverse effects.
