1. What is Mycosyst and what is it used for

Mycosyst belongs to a group of medicines called antifungals. The active substance is fluconazole.
Mycosyst is used to treat fungal infections and can also be used to prevent fungal infections.
The most common cause of fungal infections is a type of fungus called Candida.
Adults
The doctor may prescribe this medicine for the following fungal infections:

• Cryptococcal meningitis - a fungal infection of the brain,
• Coccidioidomycosis - a disease of the respiratory system,
• 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 membrane - infection of the mucous membrane 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 membrane of the mouth and throat,
• prevent relapses of fungal infections of the vagina,
• 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 to treat the following fungal infections:

• Fungal infections (thrush) of the mucous membrane - infection of the mucous membrane of the mouth and throat,
• Infections caused by Candida fungi and detected in the blood, internal organs (e.g. heart, lungs) or urinary tract,
• 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 does not function properly),
• prevent relapses of cryptococcal meningitis.

2. Important information before taking Mycosyst

When not to take Mycosyst

• If the patient is allergic to fluconazole or other medicines used to treat fungal infections or any of the other ingredients of this medicine (listed in section 6). Symptoms may include hives, skin redness, or difficulty breathing.
• If the patient is taking astemizole, terfenadine (antihistamines used to treat allergies).
• If the patient is taking cisapride (for stomach disorders).
• If the patient is taking pimozide (for mental disorders).
• If the patient is taking quinidine (for heart rhythm disorders).
• If the patient is taking erythromycin (an antibiotic used to treat infections).

Warnings and precautions

Before starting to take Mycosyst, the patient should discuss it with their doctor or pharmacist:

• if the patient has kidney or liver problems,
• if the patient has heart disease, including heart rhythm disorders,
• if the patient has blood potassium, calcium, or magnesium level disorders,
• if the patient experiences severe skin reactions (hives, skin redness, difficulty breathing),
• if the patient has ever had a severe skin rash or skin peeling after taking fluconazole,
• if the patient develops symptoms of "adrenal insufficiency", where the adrenal glands do not produce enough steroid hormones, such as cortisol (chronic or prolonged fatigue, muscle weakness, loss of appetite, weight loss, abdominal pain),
• if the fungal infection does not improve, it may be necessary to use another antifungal treatment.

In patients treated with fluconazole, there have been reports of severe skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS). If the patient experiences any of the severe skin reactions described in section 4, they should stop taking Mycosyst and seek medical attention immediately.

The doctor may also prescribe Mycosyst to children and adolescents.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, 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 a week after taking a single dose of fluconazole before becoming pregnant.
In case of longer treatment cycles with fluconazole, the patient should discuss with their doctor the need for adequate contraception during treatment and for a week after the last dose.
If the patient is pregnant, thinks they may be pregnant, or plans to have a child, 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.

Driving and using machines

While driving or operating machinery, the patient should take into account that dizziness or seizures may occasionally occur. If the patient experiences dizziness or feels unwell, they should not drive or operate machinery.
