Find out what causes a sore throat and how to relieve symptoms.

Sore Throat Causes & Treatments

A sore throat may range in severity from a mild annoyance to a debilitating condition that impacts on a person’s ability to talk, eat, drink or sleep. There are several causes of a sore throat, the most common of which is a bacterial or viral infection of the pharynx.1 They may also be due to infection by fungal spores2. Sore throats are the second most common reason people seek medical treatment3, but it is impossible to determine whether a sore throat is viral or bacterial from symptoms alone.

Povidone ‐ Iodine

Povidone ‐ Iodine is a complex produced by combining iodine and polyvinylpyrrolidone. This complex only releases a small amount of active iodine at a time, while the rest is loosely bound to the povidone molecule. When povidone‐iodine is applied to the skin, for example in the case of a cut, the active iodine is used up as it kills a broad range of bacteria. As the level of active iodine working in the wound decreases, more bound molecules of iodine become available and replenish them. This means that there is only a very small amount of iodine on the skin at a time, making povidone‐iodine less likely to cause undesirable effects such as irritation, compared with traditional iodine

Betadine® and Bacterial Sore Throat

Betadine® Sore Throat gargle is active against several bacterial strains. A method of staining, known as Gram’s stain, is used to help identify bacterial cells. Staining differences under a microscope are due to differences in cell wall structure in two groups of bacteria, known as gram positive and gram negative bacteria.10 Betadine® is effective against both these groups, including gram positive Streptococcus species, which is one of the most common causes of a bacterial sore throat. In one study, testing against 20 strains of bacteria, povidone‐iodine was found to kill all bacterial strains within 20 seconds (in laboratory studies).13 Betadine® Sore Throat Gargle is therefore a quick acting and effective treatment choice for a sore throat caused by bacteria.

Always read the label. Follow the directions for use. If symptoms persist, talk to your health professional.

Benefits of Betadine Sore Throat Gargle

Betadine Sore Throat Gargle is an ideal choice for a sore throat caused by bacteria. Betadine Sore Throat Gargle contains povidone‐iodine, which releases a low concentration of active iodine to the tissues (approximately 2 parts per million). This concentration is ideal, as it is above the level required to kill bacteria and below the level at which iodine may cause irritation.12 This makes Betadine Sore Throat Gargle an effective, yet gentle treatment of bacterial sore throats. It is available as both a concentrated and ready to use product, depending on your needs. With an easy to use measure for your convenience, you can begin treatment with Betadine Sore Throat Gargle at the first signs of a sore throat, whether at home, at the office or on holiday.

Always read the label. Follow the directions for use. If symptoms persist, talk to your health professional.
