Betadine mouthwash and gargle is a highly effective solution for relieving sore throat as it has the ability to destroy 99.9% of bacteria, sore throat viruses, common cold, and fungi. It works rapidly as a virucidal, fungicidal, and streptococcal organism treatment and is effective in treating sore throat and streptococcal tonsillitis.

Moreover, it can be used as an adjunct treatment for inflammatory diseases of the mouth and pharynx, including stomatitis, gingivitis, aphthous ulcers, tonsillitis, monilial infections, colds, and influenza. The antiviral efficacy of Betadine is useful for managing oropharyngeal hygiene in individuals exposed to respiratory viruses.

It is important to note that povidone-iodine should not be used to cover lengthy skin areas, not exceeding 10% of the total body surface and not more than 14 days unless otherwise directed. After completing the treatment, early signs of potential hyperthyroidism should be monitored for up to 3 months, and the thyroid function should be checked if necessary.
