  • Infections caused by Candida fungi and detected in the blood, internal organs (e.g., heart, lungs), or urinary tract,
  • Fungal infections (thrush) of the mucous membranes - infection of the mucous membranes of the mouth, throat, and mouth sores associated with the use of dental prostheses,
  • Fungal infections of the genital organs - infections of the vagina or penis,
  • Skin fungi - e.g., athlete's foot, body fungus, groin fungus, nail fungus.

Mycosyst can also be used to:

  • Prevent relapses of cryptococcal meningitis,
  • Prevent relapses of fungal infections of the mucous membranes,
  • Prevent relapses of vaginal fungal infections,
  • Prevent fungal infections (in patients with a weakened immune system).

Newborns, infants, children, and adolescents (from 0 to 17 years old)
The doctor may prescribe this medicine for the treatment of the following fungal infections:

  • Fungal infections (thrush) of the mucous membranes - infection of the mucous membranes of the mouth and throat,

  • Cryptococcal meningitis - a fungal infection of the brain.

Mycosyst can also be used to:

  • Prevent fungal infections (if the patient's immune system is weak and not functioning properly),
  • Prevent relapses of cryptococcal meningitis.

2. Important information before taking Mycosyst

Taking Mycosyst with food and drink

The medicine can be taken with or without food.

Pregnancy and breastfeeding

If the patient is pregnant, breastfeeding, or thinks they may be pregnant, they should consult their doctor or pharmacist before taking this medicine.
If the patient plans to become pregnant, it is recommended that they wait for one week after taking a single dose of fluconazole before becoming pregnant.
In case of longer treatment cycles with fluconazole, the patient should discuss the need for adequate contraception during treatment and for one week after the last dose with their doctor.
If the patient is pregnant, thinks they may be pregnant, or plans to become pregnant, they should not take fluconazole unless their doctor has advised them to do so. If the patient becomes pregnant or thinks they may be pregnant while taking this medicine or within one week of the last dose, they should contact their doctor.
Fluconazole taken during the first or second trimester of pregnancy may increase the risk of miscarriage. Fluconazole taken during the first trimester of pregnancy may increase the risk of birth defects of the heart, bones, and/or muscles.
There have been reports of children with birth defects of the skull, ears, and/or bones of the hip and elbow, born to mothers treated with high doses of fluconazole (400-800 mg per day) for at least 3 months for coccidioidomycosis. The relationship between fluconazole and these cases is unclear.
The patient can continue breastfeeding after taking a single dose of Mycosyst 150 mg.
The patient should not breastfeed if they are taking multiple doses of Mycosyst or if they are taking high doses of the medicine.
