Acute toxicity describes the adverse effects of a substance that result either from a single exposure [1] or from multiple exposures in a short period of time (usually less than 24 hours). [ 2 ] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance.
Methotrexate was originally developed and continues to be used for chemotherapy, either alone or in combination with other agents.It is effective for the treatment of several cancers, including solid tumours of breast, head and neck, lung, bladder, as well as acute lymphocytic leukemias, non-Hodgkin's lymphoma, osteosarcoma, and choriocarcinoma and other trophoblastic neoplasms.
In toxicology, the lowest published toxic dose (Toxic Dose Low, TD Lo) is the lowest dosage per unit of bodyweight (typically stated in milligrams per kilogram) of a substance known to have produced signs of toxicity in a particular animal species. [1]
higher potency corticosteroids, more frequent application, extended duration of treatment, [3] use of occlusion, infancy/childhood, location [2] Diagnostic method: Visual inspection of skin for visible signs of skin atrophy [1] Prevention: Intermittent maintenance therapy; increasing duration of interval between applications [4] Management

Symptoms of allergic reaction to mercaptopurine include rash, itching, swelling, dizziness, trouble breathing, and inflammation of the pancreas. In some cases, mercaptopurine may suppress the production of blood cells, both white blood cells and red blood cells. It may be toxic to bone marrow. Quarterly blood counts are necessary for people on ...
The treatment may mirror that of chemotherapy-induced myelosuppression or may be to change to an alternate drug or to temporarily suspend treatment. Because the bone marrow is the manufacturing center of blood cells, the suppression of bone marrow activity causes a deficiency of blood cells.
Alcohol can exacerbate the symptoms and may directly contribute to increased severity of symptoms. The reasons for toxicity vary depending on the mixture of drugs. Usually, most victims die after using two or more drugs in combination that suppress breathing, and the low blood oxygen level causes brain death. [6]
