PRECAUTIONS
General
Topical metronidazole has been reported to cause tearing of the eyes. Therefore, contact with the eyes should be avoided. If a reaction suggesting local irritation occurs, patients should be directed to use the medication less frequently or discontinue use. Metronidazole is a nitroimidazole and should be used with care in patients with evidence of, or history of blood dyscrasia.
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Metronidazole has shown evidence of carcinogenic activity in a number of studies involving chronic, oral administration in mice and rats but not in studies involving hamsters.
Metronidazole has shown evidence of mutagenic activity in severalin vitrobacterial assay systems. In addition, a dose-response increase in the frequency of micronuclei was observed in mice afterintraperitonealinjections and an increase in chromosome aberrations have been reported in patients with Crohn's disease who were treated with 200-1200 mg/day of metronidazole for 1 to 24 months. However, no excess chromosomal aberrations in circulating human lymphocytes have been observed in patients treated for 8 months.
Pregnancy
Teratogenic Effects
Pregnancy Category B
There are no adequate and well-controlled studies with the use of Rosadan®(metronidazole) Topical Cream in pregnant women. Metronidazole crosses the placental barrier and enters thefetal circulationrapidly. No fetotoxicity was observed after oral metronidazole in rats or mice. However, because animal reproduction studies are not always predictive of human response and since oral metronidazole has been shown to be acarcinogenin some rodents, this drug should be used during pregnancy only if clearly needed.
Nursing Mothers
After oral administration, metronidazole is secreted in breast milk in concentrations similar to those found in the plasma. Even though blood levels are significantly lower with topically applied metronidazole than those achieved after oral administration of metronidazole, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established.
CLINICAL PHARMACOLOGY
The mechanisms by which metronidazole acts in the treatment ofrosaceaare unknown, but appear to include an anti-inflammatory effect.
