Diagnostic Tests for Developmental toxicity - Cytarabine including blood tests, urine tests, swabs, diagnostic tests, lab tests, and pathology testing Side effects of vinblastine include: toxicity to white blood cells, nausea, vomiting, constipation, dyspnea, chest or tumor pain, wheezing, and 0 gfm2 may have comparably favourable pharmacological properties with less toxicity, but need Oxygen (along with anesthesia gas during general anesthesia) is breathed in during the "inspiration" phase of breathing. PML, which is sometimes fatal, commonly presents with hemiparesis, apathy, confusion, cognitive deficiencies, and ataxia [see Adverse Reactions (6.2)]. agent in patients receiving high-dose MTX and might circumvent life-threatening toxicity in patients with MTX intoxication. Monitoring of therapy could include assay of phenotypic enzyme activities or genotype in addition to, or instead of, the more traditional measurement of parent drug or drug metabolites. As CPG2 causes a predefined and considerable decline of MTX levels, this substance might be also attractive for MTX dose escalation studies. Different antimetabolite drugs are taken in different ways, depending on the drug and the type of cancer being treated. Some antimetabolites are available as tablets or liquids you take by mouth every day. Others are given by injection through an intravenous (IV) line that a health care professional inserts into a vein.
