Side Effects

Side effects of Arrow Ornidazole have been mainly limited to the gastrointestinal tract (nausea, vomiting, epigastric pain) and central nervous system (dizziness, headache, lassitude). Unlike other nitroimidazoles, Arrow Ornidazole does not interact with alcohol, although this requires further study.

Leukopenia has been described occasionally during therapy. Adverse central nervous system (CNS) effects of Arrow Ornidazole have mainly included headache, dizziness, lassitude or somnolence, fatigue and weakness. Adverse CNS effects of Arrow Ornidazole may be less than that happens with metronidazole. Seizures have not been reported with Arrow Ornidazole in studies available to date.

Precaution

In patient with ataxia, vertigo, and mental confusion, Arrow Ornidazole should be prescribed with caution. During prolonged treatment with Arrow Ornidazole, blood dyscrasia namely mild leukopenia have been reported rarely. In case leukopenia occurs, the decision to discontinue the therapy should depend upon the gravity of infection.

Interaction

Like other imidazoles, Arrow Ornidazole has a mild potential to cause disulfiramlike reactions. Concomitant administration of oral anticoagulants may increase the risk of haemorrhage due to diminished hepatic metabolism. Arrow Ornidazole has been reported to decrease the clearance of 5-fluorouracil.

Pregnancy & Breastfeeding use

Adequate clinical trials have not been conducted. Arrow Ornidazole should be prescribed only if the potential benefit justifies the potential risk to fetus/neonate.
