Nyvigan (Nystatin)

Nystatin, the active ingredient in Nyvigan, is an antifungal presented as a topical formulation for cutaneous use. It treats superficial Candida infections of the skin and mucous membranes in both adults and children. The polyene compound binds to fungal cell membranes, providing a localized therapeutic effect while exhibiting minimal systemic absorption.

GNH USA supplies Nyvigan as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company ensures quality assurance and regulatory compliance across all markets through rigorous testing and documentation.

Nystatin is used to treat superficial fungal infections caused by Candida species.

- Oral thrush (candidiasis): reduces fungal colonization in the mouth and alleviates symptoms. - Esophageal candidiasis: treats infection of the esophagus and promotes healing. - Dermatophytic infections (e.g., diaper rash, intertrigo): alleviates cutaneous Candida infection and relieves irritation. - Vaginal candidiasis: provides topical antifungal action to clear infection and reduce discharge.

Common Side Effects: - Local irritation: mild redness or itching at the application site. - Burning sensation: transient discomfort when applied to mucous membranes. - Nausea: occasional when used in the oral cavity. - Diarrhea: rare gastrointestinal upset if swallowed in large amounts.

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis): swelling, difficulty breathing, or hives. - Systemic toxicity: rare but possible with extensive absorption. - Liver enzyme elevation: uncommon, monitor if prolonged use. - Contact dermatitis: persistent skin rash at the site of application.

Before using Nyvigan, consider the following precautions: - Allergy assessment: avoid if known hypersensitivity to polyene antifungals. - Pregnancy: use only if clearly needed and after medical consultation. - Breastfeeding: caution advised; discuss with a healthcare professional. - Renal impairment: monitor as Nystatin is minimally absorbed but may accumulate. - Drug interactions: review concomitant medications for potential effects. - Store at ambient temperature: keep in original container, protect from moisture and light.

Nystatin may interact with other agents as follows:

Major Interactions (Avoid): - Systemic antifungals (e.g., amphotericin B): concurrent use may increase toxicity. - Nephrotoxic drugs: avoid high‑dose combined therapy due to potential renal stress.

Moderate Interactions (Monitor Closely): - Antacids: may reduce oral absorption of Nystatin. - Probiotics: could alter gut flora when large amounts are swallowed. - Broad‑spectrum antibiotics: may predispose to fungal overgrowth, requiring closer observation.
