"The fecal immunochemical test (FIT) is highly effective for annual colorectal cancer screening programs for average-risk patients, according to results of a study published online January 26 in the Annals of Internal Medicine.
Prior to the use of the drug, patients should be advised of the possibility of untoward symptoms.
In general, the incidence of adverse reactions attending the use of vinblastine sulfate appears to be related to the size of the dose employed. With the exception of epilation, leukopenia, and neurologic side effects, adverse reactions generally have not persisted for longer than 24 hours. Neurologic side effects are not common; but when they do occur, they often last for more than 24 hours. Leukopenia, the most common adverse reaction, is usually the dose-limiting factor.
The following are manifestations which have been reported as adverse reactions, in decreasing order of frequency. The most common adverse reactions are underlined:
Gastrointestinal: Constipation, anorexia, nausea, vomiting, abdominal pain, ileus, vesiculation of the mouth, pharyngitis, diarrhea, hemorrhagic enterocolitis, bleeding from an old peptic ulcer, rectal bleeding.
Treatment with vinca alkaloids has resulted rarely in both vestibular and auditory damage to the eighth cranial nerve. Manifestations include partial or total deafness which may be temporary or permanent, and difficulties with balance including dizziness, nystagmus, and vertigo. Particular caution is warranted when vinblastine sulfate (vinblastine sulfate injection) is used in combination with other agents known to be ototoxic such as platinum-containing oncolytics.
Cardiovascular: Hypertension. Cardiac effects such as myocardial infarction, angina pectoris and transient abnormalities of ECG related to coronary ischemia have been reported very rarely. Cases of unexpected myocardial infarction and cerebrovascular accidents have occurred in patients undergoing combination chemotherapy with vinblastine, bleomycin, and cisplatin. Raynaud's phenomenon has also been reported with this combination.
Pulmonary: See PRECAUTIONS.
Miscellaneous: Malaise, bone pain, weakness, pain in tumor-containing tissue, dizziness, jaw pain, skin vesiculation, hypertension, Raynaud's phenomenon when patients are being treated with vinblastine sulfate (vinblastine sulfate injection) in combination with bleomycin and cis-platinum for testicular cancer. The syndrome of inappropriate secretion of antidiuretic hormone has occurred with higher than recommended doses.
Nausea and vomiting usually may be controlled with ease by antiemetic agents. When epilation develops, it frequently is not total; and, in some cases, hair regrows while maintenance therapy continues.

Solutions should be made with normal saline (with or without preservative) and should not be combined in the same container with any other chemical. Unused portions of the remaining solutions that do not contain preservatives should be discarded immediately.
The simultaneous oral or intravenous administration of phenytoin and antineoplastic chemotherapy combinations that included vinblastine sulfate (vinblastine sulfate injection) has been reported to have reduced blood levels of the anticonvulsant and to have increased seizure activity. Dosage adjustment should be based on serial blood level monitoring. The contribution of vinblastine sulfate (vinblastine sulfate injection) to this interaction is not certain. The interaction may result from either reduced absorption of phenytoin or an increase in the rate of its metabolism and elimination.
Caution should be exercised in patients concurrently taking drugs known to inhibit drug metabolism by hepatic cytochrome P450 isoenzymes in the CYP 3A subfamily, or in patients with hepatic dysfunction. Concurrent administration of vinblastine sulfate (vinblastine sulfate injection) with an inhibitor of this metabolic pathway may cause an earlier onset and/or an increased severity of side effects. Enhanced toxicity has been reported in patients receiving concomitant erythromycin (see ADVERSE REACTIONS).
