Use In Pregnancy Lactation
Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Hepatab should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. Use in Lactation: It is not known whether Rifaximin is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants from Hepatab, 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.
Although In vitro studies demonstrated the potential of Rifaximin to interact with cytochrome P450 (CYP3A4), a clinical drug-drug interaction study demonstrated that Rifaximin did not significantly affect the pharmacokinetics of midazolam. An additional clinical drug-drug interaction study showed no effect of Rifaximin on the presystemic metabolism of an oral contraceptive containing ethinyl estradiol and norgestimate. Therefore, clinical interactions with drugs metabolized by human cytochrome P450 isozymes are not expected.
No specific information is available on the treatment of over dosage with Rifaximin. In case of over dosage, discontinue Rifaximin, treat symptomatically and institute supportive measures as required.
Store in cool & dry place, protect from light. Keep out of the reach of children.
