Prophylaxis in patients undergoing bone marrow transplantation:
The recommended daily dosage is 400 mg, once daily. Patients who are anticipated to have severe granulocytopenia (less than 500 neutrophils per cu mm) should start Fluconazole Injection, USP prophylaxis several days before the anticipated onset of neutropenia, and continue for 7 days after the neutrophil count rises above 1000 cells per cu mm.

Max 800–1,000 mg/day may be used for some CNS fungal infections

Precautions
Renal or hepatic impairment. May prolong QT interval. Pregnancy, lactation. CDC guidelines recommend only using topical antifungal products to treat pregnant women with vulvovaginal yeast infections, including for longer periods than usual if these infections persist or recur.
Lactation
Enters breast milk; use caution
Pregnancy-Lactation
Pregnancy
Single maternal PO dose of 150 mg for vaginal candidiasis
Results of a Danish study concludes there is a possible increased risk of miscarriage; women who are pregnant or actively trying to get pregnant should ask their physician about alternative treatments
Spontaneous abortion between 7 and 22 weeks' gestation occurred significantly more often in women exposed to oral fluconazole than unexposed pregnancies (4.43% vs. 4.25%; hazard ratio, 1.48); fluconazole was also compared with intravaginal azole antifungals to account for confounding by candidiasis, again, the oral drug was associated with significantly increased risk for spontaneous abortion - JAMA. 2016;315(1):58-67
CDC guidelines recommend only using topical antifungal products to treat pregnant women with vulvovaginal yeast infections, including for longer periods than usual if these infections persist or recur
All other indications
Use in pregnancy should be avoided except in patients with severe or potentially life-threatening fungal infections in whom fluconazole may be used if the anticipated benefit outweighs the possible risk to the fetus
A few published case reports describe a rare pattern of distinct congenital anomalies in infants exposed in-utero to high dose maternal fluconazole (400-800 mg/day) during most or all of the first trimester
Effective contraceptive measures should be considered in women of child-bearing potential who are being treated with 400-800 mg/day and should continue throughout the treatment period and for approximately 1 week (5 to 6 half-lives) after the final dose
Reported anomalies are similar to those seen in animal studies and consist of brachycephaly, abnormal facies, abnormal calvarial development, cleft palate, femoral bowing, thin ribs and long bones, arthrogryposis, and congenital heart disease
Lactation
Secreted in human milk at concentrations similar to maternal plasma concentrations; use caution (AAP Committee states "compatible with nursing")
Interactions
May increase plasma concentrations of oral hypoglycaemics (e.g. tolbutamide, glyburide, glipizide), phenytoin, theophylline, tofacitinib, rifabutin. May increase prothrombin time w/ anticoagulants. May cause significant increase in ciclosporin levels in renal transplant patients w/ or w/o renal impairment. Rifampicin reduces fluconazole levels. May increase risk of nephrotoxicity w/ tacrolimus. May increase the effect of short-acting benzodiazepines (e.g. midazolam).
Potentially Fatal: Increased risk of cardiac arrhythmias or QT prolongation w/ terfenadine, cisapride, astemizole, pimozide, quinidine, halofantrine and erythromycin.
Side Effects
Side effects of Fluconazole :
>10%
Headache (2-13%)
1-10%
Nausea (2-7%), Abdominal pain (2-6%), Diarrhea (2-3%), Rash (2%), Vomiting (2-5%)
Frequency Not Defined
QT prolongation, Torsades de pointes, Alopecia, Anaphylactic reactions, Angioedema, Cholestasis, Dizziness, Dyspnea, Hepatic failure, Hepatitis, Hypertriglyceridemia, Hypokalemia, Increased alkaline phosphatase, Increased ALT/AST, Jaundice, Leukopenia, Pallor, Seizures, Stevens-Johnson syndrome, Taste perversion, Thrombocytopenia, Toxic epidermal necrolysis
Potentially Fatal: Hepatotoxicity; rarely anaphylaxis; Stevens-Johnson syndrome.
Mode of Action
Fluconazole decreases ergosterol synthesis by interfering w/ cytochrome P450 activity, thus inhibiting cell membrane formation of susceptible fungi including B. dermatitidis, Candida spp., C. immitis, C. neoformans, Epidermophyton spp., H. capsulatum, Micosporum spp., Trichophyton spp.
