약물 상호작용

• Cyclosporine · Terbinafine may increase the elimination and decrease the efficacy of cyclosporine.
• Rifampin · May increase terbinafine clearance, potentially requiring higher terbinafine doses. · moderate
• Beta-blockers · Terbinafine shares the CYP2D6 metabolic pathway and could theoretically alter the metabolism of beta-blockers.
• MAO Inhibitors (e.g., amitraz, selegiline) · Terbinafine shares the CYP2D6 metabolic pathway and could theoretically alter the metabolism of MAOIs.
• SSRIs (e.g., fluoxetine) · Terbinafine shares the CYP2D6 metabolic pathway and could theoretically alter the metabolism of SSRIs.
• Tricyclic Antidepressants · Terbinafine shares the CYP2D6 metabolic pathway and could theoretically alter the metabolism of TCAs.
• Cimetidine · May decrease the clearance of terbinafine, potentially increasing plasma concentrations (Clinical Pearl) · moderate

모니터링

• Clinical efficacy (resolution of fungal lesions)
• Baseline liver enzymes prior to therapy
• Periodic liver enzyme monitoring as needed, especially during long-term treatment
• CBC (baseline and periodic)
• Liver function tests (ALT, AST, Bilirubin)
• Renal function tests
• Clinical response (skin scrapings, fungal cultures)

과용량

There is limited information regarding acute toxicity in veterinary species. In humans, acute ingestions of up to 5 grams have been reported without serious adverse effects. Treatment of massive overdose should be supportive and symptomatic.
