Medical Conditions to Discuss

Check with your doctor if you have any other medical conditions, take any medicines for other conditions, or currently have or have ever had a kidney problem as this product may cause toxic levels of iodine to be absorbed into your blood.

Pregnancy and Breastfeeding

During pregnancy and lactation, povidone-iodine preparations should only be used if strictly prescribed by the doctor and its use should be kept to the absolute minimum. Absorbed iodine can cross the placental barrier and can be secreted in breast milk.

Thyroid patients: Patients with thyroid disease, especially elderly patients, may be at risk of developing hyperthyroidism from large amounts of iodine

Drug Interactions

Several medications and substances can interact with Betadine Sore Throat Gargle and affect how it works.

Diagnostic tests: May show inaccurate results with diagnostic tests for blood or glucose in stool or urine due to oxidative effects

  • Lithium (for depression) – can affect thyroid gland function
  • Wound-treatment preparations containing enzymatic components
  • Disinfectants containing silver, hydrogen peroxide or taurolidine
  • Mercury derivatives – contraindicated
  • Hydrogen-peroxide mouthwash
  • Octenidine containing antiseptics
