During pregnancy and lactation, Betadine Sore Throat Spray should only be used if strictly prescribed by the physician and its use should be kept to the absolute minimum, as absorbed iodine can cross the placental barrier and can be secreted in breast milk. Povidone-iodine use may induce transient hypothyroidism in the foetus or in the newborn. Povidone-iodine should be avoided in such situations. In these cases, a check of the child’s thyroid function is necessary, especially in areas known for endemic low dietary iodine and tendency to goiter. Also, any possible ingestion of the throat spray by the infant must be absolutely avoided.
