Hypersensitivity to iodine, polyvinylpyrrolidone or to any excipient. History
of abnormal thyroid function or goitre (in particular nodular colloid goitre,
endemic goitre and Hashimoto’s thyroiditis). Use in children under two years
of age. Regular use should be avoided in patients on concurrent lithium
Special warnings and precautions for use
Use of this preparation may interfere with tests of thyroid function. Iodine is
absorbed through burns and broken skin and to a lesser extent through intact
skin and may lead to toxic levels of iodine in the blood, particularly in patients
with renal insufficiency. If symptoms occur suggesting changes in thyroid
function, these should be investigated. In patients with impaired renal
function, blood levels of iodine should be monitored.
If local irritation and hypersensitivity develop, then discontinue treatment.
Refer to section 4.8 for further information.
Betadine Antiseptic Paint can permanently discolour white gold jewellery and
it is recommended that this type of jewellery should be removed before using
Betadine Antiseptic Paint.
Interaction with other medicinal products and other forms of interaction
Use with concurrent lithium therapy has been shown to exhibit additive
hypothyroidic effects. Absorption of iodine from povidone iodine through
either intact skin or broken skin may interfere with thyroid function tests.
Contamination with povidone iodine of several types of tests for the detection
of occult blood in faeces or blood in urine may produce false-positive results.
Fertility, Pregnancy and lactation
Iodine freely crosses the placenta and is secreted in breast milk. Thyroid
function disorders have been reported in the offspring of mothers exposed to
pharmacological doses of iodine. Povidone iodine should not be used regularly
during pregnancy unless there is no alternative treatment available.
Effects on ability to drive and use machines
Local irritation, skin burns and sensitivity reactions have been reported rarely.
Anaphylactic reactions, anaphylactoid reactions and anaphylactic shock have
been reported uncommonly with products containing povidone-iodine or
Excess iodine can produce goitre and hypothyroidism or hyperthyroidism.
Such effects have occasionally been seen with extensive or prolonged use of
povidone iodine. Other effects that have been reported are metabolic acidosis
and acute renal failure.
Deliberate or accidental ingestion of large quantities of povidone iodine will
result in high blood concentrations of iodine and gastrointestinal corrosive
effects including vomiting, diarrhoea and abdominal pain. Systemic toxicity
may result in shock, hypotension, tachycardia, fever, metabolic acidosis and
renal impairment. Symptomatic and supportive treatment should be started
with special attention to monitoring electrolyte balance, renal function, thyroid
function and liver function. Haemodialysis effectively clears iodine and should
be employed in severe cases of iodine poisoning particularly if renal failure is
present. Continuous venovenous haemodiafiltration is less effective than
Povidone-iodine is a complex of iodine which shows all the broad spectrum
germicidal activity of elemental iodine. The germicidal activity is maintained
in the presence of blood, pus, serum and necrotic tissue. It is effective in the
treatment of infections caused by bacteria, fungi, yeast and viruses (e.g.
Herpes Virus Types I and II).
