Indications & Usage
INDICATIONS AND USAGE Flucytosine Capsules, USP are indicated only in the treatment of serious infections caused by susceptible strains of Candida and/or Cryptococcus .
Candida: Septicemia, endocarditis and urinary system infections have been effectively treated with flucytosine.
Limited trials in pulmonary infections justify the use of flucytosine.
Cryptococcus: Meningitis and pulmonary infections have been treated effectively.
Studies in septicemias and urinary tract infections are limited, but good responses have been reported.
Flucytosine Capsules, USP should be used in combination with amphotericin B for the treatment of systemic candidiasis and cryptococcosis because of the emergence of resistance to Flucytosine Capsules, USP (see MICROBIOLOGY ).

Warnings
WARNINGS Flucytosine Capsules, USP must be given with extreme caution to patients with impaired renal function.
Since flucytosine is excreted primarily by the kidneys, renal impairment may lead to accumulation of the drug.
Flucytosine serum concentrations should be monitored to determine the adequacy of renal excretion in such patients.
Dosage adjustments should be made in patients with renal insufficiency to prevent progressive accumulation of active drug.
Flucytosine Capsules, USP must be given with extreme caution to patients with bone marrow depression.
Patients may be more prone to depression of bone marrow function if they: 1) have a hematologic disease, 2) are being treated with radiation or drugs which depress bone marrow, or 3) have a history of treatment with such drugs or radiation.
Bone marrow toxicity can be irreversible and may lead to death in immunosuppressed patients.
Frequent monitoring of hepatic function and of the hematopoietic system is indicated during therapy.
