| methotrexate | a cytotoxic drug Trexall (tablet or IV, IM) other non-chemo indications (e.g. rheumatoid arthritis, ectopic pregnancy |
| Corticosteroids- | similar to cortisol, a hormone naturally produced in the adrenal glands and prescribed in tapering doses |
| Prolong use of Corticosteroids can cause... | adrenal suppression (body quits making cortisol). |
| Corticosteroids treat: | prevents organ rejection in transplant patients arthritis (juvenile, rheumatoid) inflammation, rash lupus ankylosing spondylitis inflammatory bowel disease Addison disease scleroderma asthma Crohn disease |
