Mycosyst-Gyno (Fluconazole)

Fluconazole, the active ingredient in Mycosyst-Gyno, is an azole antifungal presented as a tablet for oral use. It treats Candida infections such as vulvovaginal, oropharyngeal, esophageal, systemic and cryptococcal meningitis in adults and children as prescribed.

GNH USA supplies Mycosyst-Gyno as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Fluconazole is an azole antifungal that targets Candida species across a range of mucosal and systemic infections. - Vulvovaginal candidiasis: effective relief of itching, discharge and irritation caused by Candida infection. - Oropharyngeal candidiasis: eradicates yeast overgrowth in the mouth and throat. - Esophageal candidiasis: resolves fungal infection of the esophagus, improving swallowing. - Cryptococcal meningitis: used as part of combination therapy to treat fungal meningitis. - Systemic candidiasis: treats invasive Candida infections affecting blood and organs.

Fluconazole may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea: mild stomach upset or queasiness. - Headache: transient head pain. - Diarrhea: loose stools. - Abdominal pain: cramping or discomfort. - Rash: skin redness or mild itching.

Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes or liver injury. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Cardiac arrhythmias: QT interval prolongation. - Anaphylaxis: rare allergic shock. - Hematologic abnormalities: neutropenia or thrombocytopenia.

When prescribing fluconazole, clinicians should consider several precautionary measures to ensure safe use. - Liver function: assess hepatic status before initiating therapy and monitor during treatment. - Renal impairment: adjust dose in patients with severe kidney dysfunction. - Pregnancy: avoid unless benefit outweighs potential risk, as safety data are limited. - Concomitant QT‑prolonging drugs: monitor cardiac rhythm when combined. - Drug interactions: review concurrent medications for CYP450 interactions. - Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture and light.

Fluconazole interacts with several medicines through cytochrome P450 pathways and other mechanisms.

Major Interactions (Avoid): - CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may cause toxic fluconazole levels. - CYP2C9 substrates (e.g., warfarin): increased anticoagulant effect, risk of bleeding. - Certain antiretrovirals (e.g., protease inhibitors): may lead to serious toxicity.

Moderate Interactions (Monitor Closely): - Oral contraceptives: reduced efficacy, consider backup contraception. - Statins (e.g., simvastatin): increased risk of myopathy, monitor muscle symptoms. - Phenytoin: decreased fluconazole concentrations, may reduce efficacy.
