Summary

Barbiturates may reduce fluconazole exposure through enzyme induction, potentially diminishing antifungal efficacy, though the effect is likely modest. Fluconazole may also raise barbiturate levels and sedation.

What this interaction means in plain words

Fluconazole and Secobarbital have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Fluconazole belongs to Anti Fungals; Secobarbital belongs to Central Nervous System.

Evidence level: Low

Why it happens

Barbiturate enzyme induction may increase fluconazole clearance; fluconazole inhibits CYP2C19/CYP3A4 metabolism of secobarbital.
