Mycosyst (Fluconazole)

Fluconazole, the active ingredient in Mycosyst, is a systemic antifungal presented as an oral dosage form for oral use. It treats a range of fungal infections, including candidiasis of the mouth, esophagus and vagina, cryptococcal meningitis, dermatophyte infections and other systemic mycoses.

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

Fluconazole is used to treat fungal infections by targeting the Candida species and other pathogenic fungi. - Candidiasis (oropharyngeal, esophageal, vaginal): clears yeast overgrowth and relieves associated symptoms. - Cryptococcal meningitis: penetrates the central nervous system to eradicate Cryptococcus neoformans. - Dermatophyte infections: eliminates skin‑surface fungi causing ringworm and related conditions. - Systemic fungal infections: provides broad‑spectrum activity against invasive fungal pathogens.

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

Common Side Effects: - Nausea: mild to moderate stomach upset. - Headache: transient cranial discomfort. - Diarrhea: loose stools occurring during therapy. - Abdominal pain: cramping or discomfort in the stomach area. - Rash: mild skin irritation or redness.

Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes or liver injury. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - QT interval prolongation: potential cardiac rhythm disturbances. - Anaphylaxis: rare but life‑threatening allergic response. - Liver failure: acute hepatic dysfunction requiring medical attention.

Before initiating fluconazole therapy, consider the following precautions. - Assess liver function: evaluate baseline hepatic enzymes and monitor during treatment. - Review cardiac history: caution in patients with known QT prolongation or electrolyte imbalances. - Evaluate renal function: dosage adjustment may be needed in severe renal impairment. - Pregnancy and lactation: use only if the potential benefit justifies the potential risk, as safety data are limited. - Drug interactions: check for concomitant medications that may affect fluconazole metabolism. - Store at ambient temperature: keep below 25 °C, retain in original packaging, and protect from moisture.

Fluconazole interacts with several medicines; careful management is required.

Major Interactions (Avoid): - Warfarin: increased anticoagulant effect, risk of bleeding. - Simvastatin or lovastatin: elevated statin levels, risk of myopathy. - Cisapride: risk of serious cardiac arrhythmias.

Moderate Interactions (Monitor Closely): - Oral contraceptives: reduced efficacy, consider backup contraception. - Phenytoin or carbamazepine: decreased fluconazole levels, may reduce effectiveness. - Rifampin: induces metabolism, lowering fluconazole concentrations. - Ergot alkaloids: increased risk of ergotism, monitor for vasospasm. - Digoxin: possible increase in serum levels, monitor cardiac function.
