Hypersensitivity to iodine, polyvinylpyrrolidine 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 therapy. Avoid inhaling or spraying into the eyes. Betadine Dry Powder Spray should not be used in serious cavities.
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 Dry Powder Spray can permanently discolour white gold jewellery and it is recommended that this type of jewellery should be removed before using Betadine Dry Powder Spray.
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.
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.
None.
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 povidone.
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.
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.
None known.
