Betadine Throat Spray Drug Interactions

Patients must be advised to inform the doctor or pharmacist if they are using, have recently used or might use any other medicines.
The PVP-iodine complex is effective at pH values of between 2.0 and 7.0. It has to be expected that the complex will react with protein and other unsaturated organic compounds, leading to impairment of its effectiveness.
The concomitant use of wound-treatment preparations containing enzymatic components, leads to a weakening effect of both substances. Products containing mercury, silver, hydrogen peroxide, and taurolidine may interact with povidone-iodine and should not be used concomitantly. Simultaneous use with mercury products may lead to the formation of a substance, which can damage the mucosa.
Absorption of iodine from BETADINE Throat Spray may interfere with thyroid function tests or radioiodine therapy and can make a planned treatment of the thyroid with iodine impossible. After the end of the treatment, 4 weeks should be allowed before a new scintigram is carried out.
Several types of tests for detecting occult (not visible) blood in faeces or blood in urine may be affected (i.e. produce false-positive results), due to the oxidative effect of povidone-iodine.
Povidone-iodine products when used before or after application of octenidine may lead to transient dark discolourations at the application site.
