The labeling for methotrexate sodium and cytarabine should be consulted. PRECAUTIONS General Particular attention should be taken to assure the maintenance of sterile technique throughout the procedure. (See DOSAGE AND ADMINISTRATION.) Carcinogenesis, Mutagenesis, Impairment of Fertility No standard mutagenicity or carcinogenicity studies have been conducted with Elliotts B Solution. Usage in Pregnancy Pregnancy Category C All components of Elliotts B Solution are normal body constituents. Animal reproduction studies have not been conducted with Elliotts B Solution. ADVERSE REACTIONS Adverse reactions may occur with any given intrathecal injection due to the chemotherapy or the technique of intrathecal administration.  (See product labeling for methotrexate sodium and cytarabine.) Preservative-free methotrexate sodium and cytarabine should be used to minimize adverse reactions due to preservatives. If an adverse reaction does occur, discontinue the administration, evaluate the patient, institute appropriate therapeutic countermeasures and, if possible, save the remainder of the unused solution(s) for examination. OVERDOSAGE Elliotts B Solution is a diluent. In the event of a drug, fluid or solute overload following administration, evalu­ate the patient's condition, and institute appropriate corrective treatment. (See product labeling for methotrexate sodium and cytarabine.) DOSAGE AND ADMINISTRATION See product labeling for methotrexate sodium and cytarabine. Elliotts B Solution is intended for intrathecal administration only.  Elliotts B Solution does not contain antibac­terial preservatives and introduction of contaminated solutions into the cerebrospinal fluid may have extremely serious consequences. Therefore, administration of intrathecal solutions should be accomplished as soon as possible after preparation. A sterile filter-needle should be used to withdraw the contents of the ampule. Intrathecal drug products should be inspected visually for particulate matter and discoloration prior to admin­istration. Preparation and Administration Precautions Elliotts B Solution is a diluent for the cytotoxic anticancer agents, methotrexate sodium and cytarabine. Care should be exercised in the handling and preparation of infusion solutions with these products. (See product labeling for methotrexate sodium and cytarabine.)
