Diflucan is a brand name for the generic drug fluconazole [1]. Essentially, they are the same medication. Fluconazole is an antifungal medication used to treat a variety of fungal infections [2].
Why is Diflucan also called Fluconazole?
Medications are often sold under both a brand name and a generic name. Diflucan is the brand name created by the pharmaceutical company Pfizer for fluconazole [1]. Once a drug's patent expires, other companies can manufacture and sell the generic version of the drug, which is typically less expensive [3]. Fluconazole is widely available as a generic medication from various manufacturers [1][4].
What fungal infections does fluconazole treat?
Fluconazole is prescribed for infections caused by fungi such as Candida species and Cryptococcus neoformans [2]. It is commonly used to treat vaginal yeast infections, oral thrush, and fungal infections of the esophagus [2]. It can also be used for more serious fungal infections, such as meningitis caused by Cryptococcus [2].
How does fluconazole work?
Fluconazole belongs to a class of drugs called triazole antifungals [5]. It works by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes [5]. This disruption weakens the fungal cell membrane, leading to cell death and preventing the fungus from growing [5].
When does the patent for Diflucan expire?
Information on the specific patent expiration dates for Diflucan is available through specialized patent tracking resources. Websites like DrugPatentWatch.com provide detailed databases on drug patents and their expiry timelines [6].

In some countries, lower doses of fluconazole for treating uncomplicated vaginal yeast infections may be available over-the-counter [7]. However, for most indications and higher doses, fluconazole is a prescription-only medication and should be used under the guidance of a healthcare professional [2][4].

Common side effects of fluconazole can include nausea, vomiting, diarrhea, stomach pain, headache, rash, and dizziness [2]. More serious side effects, though less common, can occur and may include liver problems, severe skin reactions, and heart rhythm changes [2]. It is important to discuss any potential side effects and your medical history with your doctor before taking fluconazole [2].
How does fluconazole compare to other antifungals?
Fluconazole is effective against a broad spectrum of fungi, but its efficacy can vary depending on the specific fungal species and the site of infection [5]. Other antifungal medications exist, such as itraconazole, voriconazole, and amphotericin B, each with different spectrums of activity, routes of administration, and potential side effects [5]. The choice of antifungal medication depends on the type and severity of the infection, as well as the patient's overall health [5].
How is fluconazole administered?
Fluconazole can be administered orally (as a tablet or liquid suspension) or intravenously [2]. The route of administration and dosage are determined by the type and severity of the fungal infection [2].
