주의사항 및 금기

• Hypersensitivity to metronidazole or other nitroimidazole derivatives
• Food-producing animals (FDA prohibited)
• Pregnancy (potential teratogen, especially in early pregnancy)
• Severe hepatic disease (requires dose reduction)
• > **Neurotoxicity Warning:** In dogs, total daily doses should not exceed 65 mg/kg/day to minimize the risk of central vestibular and cerebellar toxicity. Toxicity can occur with acute high doses or chronic moderate-to-high dose therapy. * **Hepatic Impairment:** Use with caution in animals with hepatic dysfunction. Consider reducing the dose to 25-50% of the usual dose in significant liver impairment. * **Pregnancy:** Potential teratogen. Avoid use during pregnancy, particularly during the first 3 weeks of gestation, unless benefits clearly outweigh risks. * **Nursing:** Consider alternative therapy or switching to milk replacer due to potential tumorigenicity. * **Debilitated Patients:** Use with extreme caution in severely debilitated animals.

약물 상호작용

• Alcohol: May induce a disulfiram-like reaction (nausea, vomiting, cramps).
• Cimetidine: May decrease the metabolism of metronidazole, increasing the likelihood of dose-related side effects.
• Phenobarbital: May increase the metabolism of metronidazole, thereby decreasing blood levels.
• Phenytoin: May increase the metabolism of metronidazole, thereby decreasing blood levels.
• Warfarin: May prolong the prothrombin time (PT). Avoid concurrent use or intensify monitoring.
• Macrolide antibiotics: Should not be used concurrently with Spiramycin (in combination products) as the combination may be antagonistic.
