Diflucan is typically taken orally in the form of a tablet, but it can also be taken as a liquid for people who have difficulty swallowing tablets. Here’s how to use it:
- Step 1: Take the medication exactly as prescribed. If you are prescribed a single dose, take it all at once. If you are on a longer regimen, take it at the same time each day to help you remember.
- Step 2: Swallow the tablet whole with a glass of water. You can take it with or without food.
- Step 3: If you are using the oral suspension form, shake the bottle well before measuring the dose.
If you miss a dose, take it as soon as you remember unless it’s almost time for your next dose. Never take a double dose to make up for a missed one.
Fluconazole, the active ingredient in Diflucan, works by inhibiting the production of ergosterol, a key component of the fungal cell membrane. Without ergosterol, the fungal cell membrane becomes unstable and leaky, ultimately killing the fungus. This process helps to clear the infection from the body.
- Inhibits fungal growth: By targeting the cell membrane, Diflucan disrupts fungal growth and reproduction.
- Broad-spectrum antifungal: It is effective against a wide variety of fungal species, especially Candida species that cause yeast infections.
While Diflucan is generally well tolerated, it can cause some side effects, including:
- Common side effects:
- Headache
- Nausea or stomach pain
- Diarrhea
- Dizziness
- Serious side effects:
- Liver problems: Symptoms like yellowing of the skin or eyes (jaundice), dark urine, or persistent nausea should be reported to your doctor immediately, as they could indicate liver issues.
- Severe allergic reactions: Rarely, Diflucan can cause an allergic reaction, which could include rash, swelling, or trouble breathing. Seek medical attention right away if you experience these symptoms.
- Heart issues: In some cases, Diflucan may cause an abnormal heart rhythm (QT prolongation), which can be dangerous. Let your doctor know if you have a history of heart problems.
- Blood thinners (e.g., warfarin): Diflucan can interact with blood-thinning medications and increase the risk of bleeding, so your doctor may need to monitor your INR (blood clotting time).
- Other antifungals: Using Diflucan with other antifungal medications can increase the risk of side effects. Discuss any other medications you are taking with your doctor.
- Drugs that affect the liver: If you are using medications that affect liver function, your doctor may need to adjust your dose of Diflucan or choose an alternative treatment.
Always inform your doctor about all the medications you are currently taking to avoid interactions.
- Vaginal yeast infections: One 150 mg tablet taken as a single dose.
- Systemic infections or cryptococcal meningitis: A higher dose, often 400 mg on the first day, followed by 200 mg to 400 mg per day for several weeks.
- For maintenance treatment: In some cases, especially for preventing recurrent infections, the dose may be reduced to a weekly dose of 150 mg.
Always follow your doctor’s instructions regarding dosage. It’s essential not to stop the medication early, even if you start feeling better, as this can cause the infection to return.
Diflucan is a prescription-only medication, meaning you will need a healthcare provider’s prescription to obtain it. Your doctor will determine the appropriate dosage and duration based on your specific condition and needs.
