Conditions treated by flucytosine

Flucytosine is primarily used in the treatment of serious fungal infections, such as cryptococcal meningitis and systemic candidiasis.

How does flucytosine work?

Flucytosine is an antimetabolite antifungal drug, also known as 5-fluorocytosine. It is an antifungal medication used in the treatment of fungal infections. Its mechanism of action involves the conversion of flucytosine into 5-fluorouracil within the fungal cells.

Once inside the fungal cell, flucytosine is taken up by the fungal cytosine permease transporter. Enzymes within the fungal cell then convert flucytosine into 5-fluorouracil, which is further metabolized into 5-fluorouridine triphosphate (5-FUTP) and 5-fluorodeoxyuridine triphosphate (5-FdUTP).

These metabolites interfere with fungal RNA and DNA protein synthesis by inhibiting the enzymatic activity of thymidylate synthase and RNA synthetase, respectively. This disruption of nucleic acid synthesis ultimately leads to the inhibition of fungal cell growth and replication, leading to the death of the fungal cells.

It is important to note that flucytosine is primarily used as combination therapy with other antifungal medications, such as amphotericin B, to enhance its efficacy and reduce the risk of drug resistance.

Forms of flucytosine available

Flucytosine is available in the form of oral capsules.

Dosage of flucytosine

The dosage of flucytosine may vary depending on the specific fungal infection being treated, the severity of the infection, and individual patient factors. It is important to follow the prescribed dosage instructions provided by the healthcare provider.

Directions for flucytosine use

Flucytosine should be taken exactly as directed by the healthcare provider. The capsules should be swallowed whole with water. It is important to complete the full course of treatment, even if the symptoms improve before the completion of the prescribed duration.

Warnings and precautions for flucytosine

  • Flucytosine should be used with caution in individuals with impaired renal function or a history of bone marrow suppression
  • Flucytosine is broken down by the liver, so individuals with liver disease or impairment should exercise caution while taking this medication. Dose adjustments may be necessary in such cases
  • Flucytosine’s use requires monitoring and extreme caution in patients with hepatic, renal, and hematologic insufficiency
  • Closely monitoring patients taking flucytosine is essential to ensure their safety and efficacy during treatment for fungal infections caused by Candida or Cryptococcus species
  • Like other antifungal medications, the development of resistance to flucytosine is possible. It is important to complete the full course of treatment as prescribed by your healthcare provider to minimize the risk of relapse
  • It may interact with certain medications, including other antifungal agents, certain chemotherapy drugs, and medications that affect kidney function. It is important to inform the healthcare provider about all medications being taken

Drug interactions

Flucytosine is contraindicated with certain immunosuppressant drugs, anticoagulants, anticonvulsant drugs and antibiotics. Always speak to your healthcare provider about the drugs you are taking.

Use of flucytosine during pregnancy

The use of flucytosine during pregnancy should be carefully considered, and the potential risks and benefits should be discussed with a healthcare provider.

Use of flucytosine while breastfeeding

Flucytosine may pass into breast milk, and its use during breastfeeding is generally not recommended. Consultation with a healthcare provider is necessary to assess the potential risks and benefits.

Possible side effects of flucytosine

Common side effects of flucytosine include gastrointestinal disturbances, such as nausea and vomiting, as well as diarrhea. Skin rashes and allergic reactions may also occur. It is important to monitor for more serious adverse effects, such as bone marrow suppression or liver toxicity. In case of these potentially serious side effects, medical attention should be sought immediately. To manage the side effects of flucytosine, it is crucial to adhere to the prescribed dosing schedule and avoid drug interactions with other antimycotic drugs like amphotericin B.

Similar drugs to flucytosine

Other antifungal medications used to treat fungal infections include fluconazole, itraconazole, and amphotericin B.
