Adverse reactions to furazolidone and other drugs. A comparative review

Furazolidone is a synthetic nitrofuran with a broad spectrum of antimicrobial action and has been widely used in the treatment of gastrointestinal infections. This article reviews the adverse reactions to furazolidone reported in the world literature. Of 10,443 adults and children who were treated with the drug, approximately 8.3% (864) experienced such reactions. Because some of these patients had more than 1 adverse reaction, 1178 reactions were reported in these studies. Nausea with vomiting, the commonest adverse reaction, was reported by 51% of the 864 patients who experienced adverse reactions. The authors compare the adverse reactions to furazolidone with those reported for other antimicrobial and antiprotozoal drugs that are frequently used to treat gastrointestinal infections.
