Side Effects

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

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

Precaution

In patient with ataxia, vertigo, and mental confusion, Orizole should be prescribed with caution. During prolonged treatment with Orizole, 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, Orizole has a mild potential to cause disulfiramlike reactions. Concomitant administration of oral anticoagulants may increase the risk of haemorrhage due to diminished hepatic metabolism. Orizole has been reported to decrease the clearance of 5-fluorouracil.

Pregnancy & Breastfeeding use

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

Contraindication

Previous hypersensitivity to Orizole and to other nitroimidazoles. Orizole 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.

Hepatic Impairment Severe: Double the interval between doses.
