Furazolidone inhibits some enzymes including monoamine oxidase. It is less potent phenelzine but may enhance the effects of indirect-acting sympathomimetics and anti-depressants foods with a high tyramine content and alcohol should be avoided.
Acute hemolytic anemia may occur in patients with a genetic deficiency of glucose-6-phosphate dehydrogenate. Agranulocytosis has been repoted.
Metronidazole has been reported to cause potentiation of oral anti-coagulant therapy, prothrombin times should be monitored during co-administration.
Use in pregnancy and lactation
Metronidazole crosses the placental barrier and enters the foetal circulation rapidly. When administered to nursing mothers, it is secreted in breast milk. Although metronidazole has not been shown to be teratogenic in either animal or human studies, data is not adequate to rule out a possible teratogenic effect. Therefore Dependal should not be used in the first trimester of pregnancy.
Nausea, vomiting, headache, gastro-intestinal discomfort, unpleasant taste and a mild rash may occur and may be minimized or eliminated by reduction in dosage.
Darkening of urine due to metabolites of furazolidone has been reported.
