diclofenac is classified in the Nonsteroidal Anti-Inflammatory Drug (NSAID) drug class, while voriconazole sits within the Azole Antifungal class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are split between OTC and prescription status, which affects access and supervision.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, diclofenac has 50,226 submissions while voriconazole has 7,600. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to voriconazole interferes with the enzyme that clears diclofenac from your blood, which can cause the drug to reach higher levels than intended.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
