Diflucan and Fluconazole: U.S. Product and Availability Questions

Diflucan is the brand name for fluconazole in an FDA-approved prescription antifungal product line. Fluconazole is the active ingredient and is also available in separately labeled generic prescription products. A pharmacy listing for generic fluconazole is therefore not the same thing as a listing for the Diflucan brand.

U.S. labeling and dosage forms

The current DailyMed record for Diflucan is an FDA prescription-drug label under the Roerig/Pfizer product record. The label describes fluconazole tablets and powder for oral suspension. The branded tablet record includes 50 mg, 100 mg, 150 mg, and 200 mg strengths, while oral-suspension products use separate concentrations and package records.

The historical URL of this page includes the words "over-the-counter," but that wording should not be used to determine current U.S. status. Diflucan and U.S. prescription fluconazole products are prescription medicines.

Current branded-package status matters

An active FDA label does not mean every historical package is still being marketed. In the April 2026 DailyMed record, the displayed Diflucan 150 mg tablet package has a marketing end date of September 30, 2023. The displayed 200 mg tablet packages have marketing end dates in May and June 2025. The same label also contains other Diflucan product records, including an oral-suspension record without a listed marketing end date.

That is why a reader looking specifically for a 150 mg or 200 mg brand-name Diflucan tablet should verify current availability rather than assuming an old branded package remains in normal distribution. Generic fluconazole has its own product labels and may have different availability and pricing.

Price and brand-versus-generic questions

Cost can vary by whether the prescription is filled with a brand or generic product, by strength and dosage form, insurance coverage, pharmacy pricing, and package size. An old advertised per-pill price is not a reliable current price and does not establish a current King Pharmacy offer.

Before filling a prescription, verify whether the prescriber specified a brand or whether a generic product may be used, the exact strength and dosage form, and whether the requested branded package is currently available. King Pharmacy's publication of this page does not mean a particular Diflucan or fluconazole product is in stock.

Prescription and safety context

Fluconazole has clinically important interactions and precautions, and the appropriate regimen depends on the infection and patient-specific factors. This page is intended for product research, not individualized treatment instructions. Use the prescription directions and current labeling for the actual product dispensed, and ask a pharmacist or prescriber about interaction or safety questions.
