Can Betadine Gargle cause dryness or a bitter taste?

Dear Reader,

Yes, what you’re experiencing, a dry mouth and bitter taste, is actually quite common after using Betadine Gargle. This gargle contains povidone-iodine, an antiseptic that kills bacteria and viruses in the throat. However, it can sometimes dry out the mouth or leave a temporary bitter or metallic taste.

Here’s why it happens:

• Povidone-iodine can slightly irritate the mouth and throat, especially when used frequently or at a high concentration.
• It may also temporarily alter your taste due to its iodine content.

This effect is usually mild and short-lived. You can try the following to ease the discomfort:

• Rinse your mouth with plain water, 5-10 minutes after gargling to remove any leftover solution.
• Drink more water throughout the day to reduce dryness.
• If you’re using undiluted Betadine Gargle, try diluting it with warm water (1 part Betadine Gargle to 2–3 parts water).

If the dryness, burning, or bitterness becomes strong or lasts more than a couple of days, it’s best to pause use and consult your doctor. They might suggest using it less frequently or switching to a milder alternative, such as saltwater gargles.

In short, yes, the bitter taste and dryness are fairly common and usually temporary, but diluting the gargle and rinsing afterwards can help reduce irritation.

Wishing you good health.
