This medication should be used with increased caution if you have kidney problems. Flucytosine may cause decreased kidney function and liver problems. In addition, this medication may decrease bone marrow function. This serious, possibly life-threatening side effect may lead to a low number of blood cells such as red cells, white cells, and platelets. This effect can cause anemia, decrease your body's ability to fight an infection, and cause bleeding problems. Your doctor will check the results of your kidney, liver, and blood tests and adjust your treatment to reduce your risk for these side effects. See also Side Effects section.
How to use Flucytosine
Take this medication by mouth, usually 4 times a day (every 6 hours), or as directed by your doctor. To reduce stomach upset, do not swallow all of the capsules for one dose at the same time. It may be best to swallow the capsules for each dose over a 15-minute period until the full dose is taken.
The dosage is based on your medical condition, weight, and response to treatment.
This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.
Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow the fungus to continue to grow, which may result in a return of the infection.
Tell your doctor right away if your condition persists or worsens.
