Trexate 50 mg Injection (Methotrexate) is a prescription medicine used in the treatment of certain cancers and autoimmune diseases where immune‑modulating therapy is needed. Methotrexate belongs to a class of drugs called antimetabolites, which work by interfering with the growth and division of rapidly dividing cells. Trexate should be administered by trained medical professionals through intravenous or intramuscular injection in a clinical setting, with ongoing monitoring of blood counts and organ functions to manage side effects and ensure safety.
