Diflucan (fluconazole): overview, dosing, safety, and how to order
Quick summary
Diflucan is the brand name for fluconazole, a triazole antifungal supplied as oral tablets and an oral suspension. This page summarizes product facts, safety points and practical buying guidance for readers searching to buy diflucan, buy diflucan online, or check diflucan price in the United States. Safety and product data below are drawn from the FDA.
What Diflucan is and approved uses
Diflucan (FLUCONAZOLE) is described by the FDA as the first of a subclass of synthetic triazole antifungal agents. The manufacturer listed in the FDA product record is Roerig. According to the FDA, Diflucan is indicated for several fungal infections including vaginal candidiasis (vaginal yeast infections), oropharyngeal and esophageal candidiasis, systemic Candida infections, cryptococcal meningitis, and to decrease candidiasis incidence in certain bone marrow transplant patients. Specimens for fungal culture and other relevant tests should be obtained when appropriate, and therapy adjusted to culture results when available (FDA).
Dosage forms and typical adult dosing
Per the FDA record, Diflucan tablets are available in 50 mg, 100 mg, 150 mg, and 200 mg strengths; oral suspension is supplied as powder (350 mg or 1400 mg per bottle) that yields reconstituted concentrations of 10 mg/mL or 40 mg/mL after mixing according to the label. The FDA lists common dosing examples:
- Vaginal candidiasis: single 150 mg oral dose.
- Oropharyngeal candidiasis: 200 mg on day one, then 100 mg once daily (treatment generally continued at least two weeks).
- Esophageal candidiasis: 200 mg on day one, then 100 mg once daily; doses up to 400 mg/day may be used based on response.
- Cryptococcal meningitis and prophylaxis regimens have higher or prolonged dosing; consult the FDA label for specifics.
The FDA also provides dosing guidance for systemic Candida infections and notes that oral absorption is rapid and essentially complete; oral and intravenous systemic dosing produce similar plasma levels (FDA).
Pediatric dosing and patients with renal impairment
The FDA product information includes pediatric dosing regimens by age and weight for oropharyngeal, esophageal, and systemic infections. Recommended pediatric doses vary by indication and age; for example, oropharyngeal candidiasis in children 6 months and older may start with a 6 mg/kg loading dose followed by 3 mg/kg daily. The label also specifies loading and maintenance schedules for systemic infections and for patients on ECMO. Because fluconazole is cleared mainly by the kidney, the FDA provides dose-adjustment guidance for impaired renal function and for patients undergoing hemodialysis.
Key safety considerations and warnings (FDA)
The FDA identifies several important safety topics to consider before and during treatment:
- Hepatic injury: Rare but serious hepatic toxicity and fatalities have been reported, mainly in patients with serious medical conditions. Monitor liver function when indicated and stop therapy if signs of liver disease develop.
- Anaphylaxis and severe skin reactions: Rare cases of anaphylaxis and exfoliative skin disorders (including severe reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis) have been reported.
- Potential fetal harm: Case reports associate high-dose or prolonged fluconazole exposure in pregnancy with distinct congenital anomalies; the FDA product information discusses risks for pregnant patients and advises counseling and contraceptive considerations for specified high-dose regimens.
These safety points and additional warnings are summarized from the FDA label; clinicians should consult the full prescribing information for clinical decisions (FDA).
Contraindications and drug interactions
According to the FDA, Diflucan is contraindicated in patients with known hypersensitivity to fluconazole or any excipient listed in the product. The label also warns against coadministration with certain medications that both prolong the QT interval and are CYP3A4 substrates (for example, some antiarrhythmics and macrolides listed in the label), which is noted as contraindicated in the product record.
Because interactions and contraindications depend on each patient's full medication list and medical history, consult a clinician or pharmacist before starting therapy.
Adverse reactions and monitoring
The FDA reports that Diflucan is generally well tolerated but lists commonly observed adverse events such as headache, nausea, abdominal pain, diarrhea, and taste perversion. In trials and post-marketing experience there have also been reports of hepatic enzyme elevations, hematologic changes, QT prolongation, and rare severe dermatologic reactions. The product record describes higher adverse event reporting among patients with serious comorbidities. Routine monitoring should follow clinical judgment and the FDA label recommendations.
Ordering, pricing, and payment guidance (buying online in the US)
Searches for phrases such as buy diflucan online, diflucan online pharmacy, buy diflucan without prescription, buy diflucan no prescription, diflucan no prescription, and diflucan no insurance are common among US shoppers. If you plan to order diflucan online or check diflucan price and diflucan cost, consider these practical points:
- Verify the pharmacy: Confirm the online pharmacy is licensed to dispense medications in the United States and displays clear contact and licensing information.
- Confirm dispensing rules: The FDA product record indicates Diflucan is a HUMAN PRESCRIPTION DRUG. That means clinician authorization and appropriate dispensing oversight apply; consumers asking about no prescription or without prescription availability should check local and online pharmacy policies and applicable laws rather than assume the product can be legally supplied without clinician authorization.
- Price and payment: Prices and discounts vary by vendor. If you have no insurance or choose to buy diflucan without insurance, compare published diflucan price and diflucan cost across licensed pharmacies and look for transparent payment options. Do not rely on any single price claim; verify current price and shipping terms before ordering.
- Ordering process: When you order diflucan online, expect the pharmacy to request medical or prescriber information and to follow established verification procedures. The phrase order diflucan online is commonly used, but responsible vendors will follow applicable dispensing and safety checks.

Many people search for buy diflucan no prescription or buy diflucan without prescription. The FDA product record classifies Diflucan as a HUMAN PRESCRIPTION DRUG, and appropriate clinician oversight is indicated by the labeling.

How much does Diflucan cost if I have no insurance?
Searches for diflucan price, diflucan cost, and buy diflucan without insurance reflect real cost concerns. The FDA label does not list retail prices or coverage details.

For the oral suspension, follow mixing and storage directions from the product label. For clinical decisions about duration and monitoring, follow FDA dosing guidance and your prescriber's instructions.
What should I watch for in terms of side effects?
