What is Mastex?
There are many brands and forms of povidone Mastex topical available. Not all brands are listed on this leaflet.

Some forms of povidone Mastex topical are used inside the mouth to provide temporary relief of minor mouth pain or irritation, sore throat, or canker sore pain.
Mastex may also be used for purposes not listed in this medication guide.

Mastex side effects
See also:
What are the possible side effects of Mastex?
Mastex and iodides, whether applied topically or given systemically, can give rise to hypersensitivity reactions which may include urticaria, angioedema, cutaneous haemorrhage or purpuras, fever, arthralgia, lymphadenopathy, and eosinophilia.
Inhalation of Mastex vapour is very irritating to mucous membranes.
Mastex and iodides have variable effects on the thyroid and can produce goitre and hypothyroidism as well as hyperthyroidism (the Iod-Basedow or Jod-Basedow phenomenon). Goitre and hypothyroidism have also occurred in infants born to mothers who had taken iodides during pregnancy.
Prolonged use may lead to a range of adverse effects, often called ’iodism’, some of which may again be due to hypersensitivity. Adverse effects include metallic taste, increased salivation, burning or painful mouth; there may be acute rhinitis, coryza-like symptoms, and swelling and inflammation of the throat. Eyes may be irritated and swollen and there may be increased lachrymation. Pulmonary oedema, dyspnoea, and bronchitis may develop. Skin reactions include acneform or, more rarely, severe eruptions (iododerma). Other reported effects include depression, insomnia, impotence, headache, and gastrointestinal disturbances, notably nausea, vomiting, and diarrhoea.
