Side Effects
Side effects of Orni have been mainly limited to the gastrointestinal tract (nausea, vomiting, epigastric pain) and central nervous system (dizziness, headache, lassitude). Unlike other nitroimidazoles, Orni does not interact with alcohol, although this requires further study.
Leukopenia has been described occasionally during therapy. Adverse central nervous system (CNS) effects of Orni have mainly included headache, dizziness, lassitude or somnolence, fatigue and weakness. Adverse CNS effects of Orni may be less than that happens with metronidazole. Seizures have not been reported with Orni in studies available to date.
Precaution
In patient with ataxia, vertigo, and mental confusion, Orni should be prescribed with caution. During prolonged treatment with Orni, 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, Orni has a mild potential to cause disulfiramlike reactions. Concomitant administration of oral anticoagulants may increase the risk of haemorrhage due to diminished hepatic metabolism. Orni has been reported to decrease the clearance of 5-fluorouracil.
Pregnancy & Breastfeeding use
Adequate clinical trials have not been conducted. Orni should be prescribed only if the potential benefit justifies the potential risk to fetus/neonate.
Contraindication
Previous hypersensitivity to Orni and to other nitroimidazoles. Orni is contraindicated in central nervous system disorders, particularly in epilepsy or in peripheral neuropathy.
Acute Overdose
Renal Impairment Haemodialysis patients: Give a supplemental dose (50% of the usual dose) before dialysis.
