Definition of Speech Impairment. A speech impairment is a condition in which the ability to produce speech sounds that are necessary to communicate with others is impaired. Speech impairments can be mild, such as occasionally mispronouncing a couple of words, to severe, such as not being able to produce speech sounds at all.
methotrexate (Oral route) Only use for life-threatening neoplastic disease or severe rheumatoid arthritis and psoriasis unresponsive to other therapies. Death, fetal death and/or congenital anomalies, lung disease, tumor lysis syndrome, fatal skin reactions, and Pneumocystis carinii pneumonia have been reported.
Methotrexate use has rarely caused serious (sometimes fatal) side effects, such as lung problems, lung infections (Pneumocystis jiroveci pneumonia), skin reactions, diarrhea, and mouth sores (ulcerative stomatitis). (See also Side Effects section.) Lumps (tumors/abnormal growths) may very rarely appear during methotrexate use.
