Interactions between your drugs
chloramphenicol multivitamin, prenatal
Applies to: chloramphenicol and Aminatal Plus (multivitamin, prenatal)
MONITOR: Chloramphenicol can cause bone marrow depression and inhibit red blood cell maturation, which may interfere with the therapeutic effects of iron or vitamin B12 in the treatment of anemia. In a group of 22 patients receiving iron dextran for iron deficiency anemia, 10 patients who also received chloramphenicol had inadequate hematologic response to the iron therapy. Four patients receiving vitamin B12 for pernicious anemia were also unresponsive to the B12 therapy while being treated with chloramphenicol. Reversible bone marrow depression is more likely to occur at higher chloramphenicol dosages that produce serum levels of 25 mcg/mL or greater.
MANAGEMENT: Patients with preexisting anemia should preferably not receive chloramphenicol due to the drug's depressive effect on bone marrow and reticulocytes. If use is unavoidable, the lowest effective dosage of chloramphenicol should be given. Hematologic response to iron or vitamin B12 therapy should be closely monitored.

Drug and food interactions
multivitamin, prenatal food
Applies to: Aminatal Plus (multivitamin, prenatal)
ADJUST DOSING INTERVAL: Concomitant use of some oral medications may reduce the bioavailability of orally administered iron, and vice versa.
Food taken in conjunction with oral iron supplements may reduce the bioavailability of the iron. However, in many patients intolerable gastrointestinal side effects occur necessitating administration with food.
MANAGEMENT: Ideally, iron products should be taken on an empty stomach (i.e., at least 1 hour before or 2 hours after meals), but if this is not possible, administer with meals and monitor the patient more closely for a subtherapeutic effect. Some studies suggest administration of iron with ascorbic acid may enhance bioavailability. In addition, administration of oral iron products and some oral medications should be separated whenever the bioavailability of either agent may be decreased. Consult the product labeling for specific separation times and monitor clinical responses as appropriate.
