Excipient(s) with known effect:
Excipients with known effect: ethanol, methyl parahydroxybenzoate (E218), propyl parahydroxybenzoate (E216), sodium and sucrose.
For the full list of excipients, see section 6.1.
The prevention and treatment of candidal infections of the oral cavity, oesophagus and intestinal tract. The suspension provides effective prophylaxis against oral candidosis in those born of mothers with vaginal candidosis.
For the treatment of denture sores, and oral infections in adults caused by C.albicans, 1 ml of the suspension should be dropped into the mouth four times daily; it should be kept in contact with the affected areas as long as possible.
In intestinal and oral candidosis (thrush) in infants and children, 1 ml should be dropped into the mouth four times a day. The longer the suspension is kept in contact with the affected area in the mouth, before swallowing, the greater will be its effect.
For prophylaxis in the newborn the suggested dose is 1 ml once daily.
No specific dosage recommendations or precautions.
In the prevention and treatment of candidiasis, the dosage regimen for Nystan should be continued for at least 48 hours after symptoms have disappeared. If signs and symptoms worsen or persist (beyond 14 days of treatment), the patient should be reevaluated, and alternate therapy considered.
Hypersensitivity to the active substance(s) or to any of the excipients listed in section 6.1.
Nystan Oral Suspension contains sucrose.
Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.
This medicinal product contains small amounts of ethanol (alcohol), less than 100 mg per dose.
This medicinal product contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) which may cause allergic reactions (possibly delayed).
Nystan oral preparations should not be used for treatment of systemic mycoses.
Animal reproductive studies have not been conducted with nystatin.
It is not known whether nystatin can cause foetal harm when administered to a pregnant woman or can affect reproductive capacity, however absorption of nystatin from the gastro-intestinal tract is negligible. Nystatin should be prescribed during pregnancy only if the potential benefits to be derived outweigh the potential risk to the foetus.
It is not known whether nystatin is excreted in human milk. Although gastrointestinal absorption is insignificant, caution should be exercised when nystatin is prescribed for a nursing woman.
Nystatin is generally well tolerated by all age groups, even during prolonged use. If irritation or sensitisation develops, treatment should be discontinued. Nausea has been reported occasionally during therapy.
Large oral doses of Nystatin have occasionally produced diarrhoea, gastrointestinal distress, nausea and vomiting. Rash, including urticaria, has been reported rarely. Steven-Johnson Syndrome has been reported very rarely. Hypersensitivity and angioedema, including facial oedema have been reported.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard
Since the absorption of nystatin from the gastro-intestinal tract is negligible, overdosage or accidental ingestion causes no systemic toxicity. Oral doses of nystatin in excess of 5 million units daily have caused nausea and gastrointestinal upset.
