Frequently Asked Questions

Our studies have looked at total symptoms and we have demonstrated that BETADINE COLD DEFENCE will reduce the total symptoms such as runny nose, nasal congestion, sore throat, etc. when given as an early intervention for treatment of common cold and flu-like illness.

Carrageenan is commonly found in food products and is generally recognised as safe. You have to remember there are three different types of carrageenan: iota, kappa and lambda. The BETADINE COLD DEFENCE spray only contains one type of carrageenan, which is the iota-carrageenan, and the iota-carrageenan is generally well tolerated.

You can continue to use the saline spray to remove crusting and wash the nose. But you should always use the BETADINE COLD DEFENCE after the saline spray, otherwise you are going to wash out the Cold Defence and reduce its efficacy. Always seek the advice of your physician with any questions you may have.
