About Diflucan

Diflucan, manufactured by Pfizer, contains fluconazole an azole antifungal as the active ingredient. Diflucan is used for the treatment of non-systemic Candida infections of the vagina (yeast infections), throat, and mouth. It is also used to prevent fungal infections in people with a weakened immune system caused by bone marrow transplant, cancer treatment, or AIDs.

NowPatient offers Diflucan for the treatment of thrush only, following an online consultation with a prescribing clinician.

Key facts of Diflucan

  • For the treatment of vaginal candidiasis, thrush, oral thrush, esophageal candidiasis, other candida infections or fungal meningitis
  • Diflucan has some common side effects which include nausea and diaarhea
  • It can be dangerous if you take Diflucan with certain medications. If you’re not sure if it is safe, discuss this with the prescribing clinician

Who is Diflucan not suitable for?

Diflucan may not be suitable for some people. To make sure it’s safe for you, speak to the prescribing clinician before taking Diflucan if you:

  • Are allergic to fluconazole or other antifungals such as ketoconazole, miconazole, or voriconazole
  • Have kidney or liver disease
  • Have high blood potassium levels
  • Have heart problems

How and where to get Diflucan?

Diflucan is available from a number of sources. It is available on prescription or over the counter at a pharmacy.

NowPatient does not allow customers to buy Diflucan directly. Our service is certified, safe and effective, and we only ever treat conditions. If you book a consultation with a prescribing clinician for the treatment of thrush, you can discuss if Diflucan is a suitable treatment option for you.

At the end of the consultation, the clinician will decide if a treatment plan is suitable for you. If it is, the clinician will issue you with a prescription which can then be ordered, paid for and delivered directly to your chosen address by NowPatient.

Diflucan is available as a 150 mg capsule or oral suspension when used for thrush.
