Diflucan, known generically as fluconazole, is an antifungal medication that treats fungal infections. It works by disrupting fungal cell membrane synthesis. Thrush, also medically termed candidiasis, is a common fungal infection caused by Candida yeast, naturally present in the body. It often appears in warm, moist areas like the mouth (oral thrush) or vagina (vaginal thrush), and Diflucan is a common treatment. This article provides general information regarding Diflucan and thrush, but it is not a substitute for professional medical advice.
Specific Dosages for Thrush
The typical dosage of Diflucan for thrush varies depending on the specific location and severity of the infection. For vaginal candidiasis, a single oral dose of 150 mg of Diflucan is commonly prescribed.
For oral thrush, or oropharyngeal candidiasis, adults typically begin with a loading dose of 200 mg on the first day. This initial higher dose helps achieve therapeutic levels quickly. Following the loading dose, the regimen usually continues with 100 mg once daily for at least two weeks. Treatment duration may extend beyond two weeks to decrease the likelihood of the infection returning. Dosages can be adjusted by a healthcare provider based on the patient’s response and the infection’s severity.
Administering Diflucan
Diflucan can be taken orally, either as a tablet or a liquid suspension. It can be consumed with or without food; taking it with food might help reduce stomach upset.
For multi-day regimens, take Diflucan at approximately the same time each day. Complete the full prescribed course of treatment, even if symptoms improve earlier, to prevent recurrence or make future treatment more difficult. If a dose is missed, take it as soon as remembered, unless it is almost time for the next scheduled dose. In that case, skip the missed dose to avoid taking double the amount.
Important Considerations When Using Diflucan
Fluconazole can cause common, mild side effects like headache, nausea, diarrhea, stomach pain, and dizziness. These usually resolve after treatment. Rarely, more serious side effects can occur.
Serious side effects requiring immediate medical attention include signs of liver damage (yellowing skin or eyes, dark urine, unusual fatigue), severe skin reactions like blistering, and changes in heart rhythm. Fluconazole can interact with many other medications, potentially altering their effectiveness or increasing adverse effects. These interactions may involve blood thinners like warfarin, certain heart medications, and some antidepressants.
Patients should inform their healthcare provider about all medications they are taking, including over-the-counter drugs, vitamins, and herbal supplements. Diflucan should be used with caution or avoided in individuals with pre-existing liver conditions or irregular heartbeats. Pregnant individuals should discuss alternatives with their doctor, as fluconazole may pose risks during pregnancy, especially in the first trimester. If symptoms do not improve, worsen, or if any severe side effects develop, prompt medical consultation is necessary.
