Important information about Diflucan

How does Fluconazole work?

The active ingredient in Fluconazole is fluconazole itself. Fluconazole (Diflucan) is an azole antifungal medicine that prevents the fungus from producing a protective covering. This prevents the fungus from growing or surviving.

How do you use Fluconazole?

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Fluconazole. However, the following is a synopsis of the general guidelines for the use of Fluconazole:

  • Fluconazole oral tablets and liquid suspension are consumed by mouth. Fluconazole injection is administered as an infusion into a vein by a healthcare provider.
  • Even if your symptoms resolve fast, continue to take fluconazole for the recommended period of time.
  • Skipping doses increases your risk of developing a drug-resistant infection.
  • Fluconazole does not treat viral infections like the flu or the common cold.

What are the side effects of Fluconazole?

Some mild or common side effects of Fluconazole seen in clinical trials as compared to placebo include:

  • Headaches.
  • Nausea and vomiting.
  • Stomach pain.
  • Dizziness.
  • Urinary tract infections.

Some individuals may experience serious side effects while using Fluconazole. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

  • Liver damage symptoms include nausea, vomiting, fatigue, stomach pain, yellowing of the skin or whites of the eyes (jaundice), dark urine, and pale stool.
  • Serious allergic reactions and skin responses include hives, skin rash, blisters, swelling of the lips or tongue, difficulty breathing, reddening, scaling, and itching.
  • Abnormal cardiac rhythm (QT prolongation) symptoms include chest pounding, shortness of breath, chest pain, and a sense of fainting or lightheadedness.

These are not all of the possible side effects of Fluconazole. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

What are the warnings or precautions for Fluconazole?

Before starting Fluconazole, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including:

  • Liver problems or liver disease.
  • Kidney disease.
  • Low levels of potassium in the blood.
  • Heart problems, such as irregular heart rhythm.
  • The liquid form of fluconazole contains sucrose. Talk to your doctor before taking this form of fluconazole if you have a problem digesting sugars or milk.

Are there any contraindications with Fluconazole?

Taking some drugs that can lengthen the QT interval (the time when your heart resets after each pump).

How long does it take Fluconazole to work?

Fluconazole normally begins to work within one day of taking it, but the time it takes to feel completely relieved varies depending on the type and severity of infection. Symptoms of vaginal yeast infections usually improve within one to three days, but it might take up to a week to fully recover. More serious fungal infections (such as those affecting the blood, lungs, or other organs) often require many days to weeks of treatment to fully resolve.

What interacts with Fluconazole?

When Fluconazole is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:

  • Voriconazole.
  • Amiodarone.
  • Atorvastatin.
  • Erythromycin.
  • Itraconazole.
  • Ketoconazole.
  • Pimozide.
  • Quinidine.
  • Warfarin.
  • Glyburide.
  • Losartan
  • Theophylline.
  • Cyclosporine.

For mouth, throat, or esophageal candidiasis, the normal dose is 200 mg orally on the first day, followed by 100 mg once daily. Treatment usually lasts at least two weeks.

Can Fluconazole be used if I am pregnant?
