Povidone-iodine is a common antiseptic you’ve probably seen in first-aid kits and clinics. It kills bacteria, viruses, and fungi on skin and surfaces. People use it for small cuts, surgical prep, and sometimes as a diluted mouthwash for throat germs. This guide tells you practical steps, safe concentrations, and when to stop using it.
Most over-the-counter products are labeled 10% povidone-iodine. That’s the usual skin prep strength. For a simple scrape: wash the area with clean water first, dry gently, then swab a small amount of povidone-iodine on the wound. Let it air-dry before putting on a bandage. For injections or minor procedures, apply and let it fully dry — do not wipe it off right away.
If a product or clinician recommends a mouth or throat rinse, that is always diluted. A safe working range for gargles in studies is around 0.5–1%, but follow the product label or your provider’s instructions. Never swallow the solution. For wound irrigation, some clinicians use diluted povidone-iodine (lower than the 10% bottle) — again, follow instructions or ask a healthcare professional.
Use only a thin layer on skin. Don’t soak large open wounds for long periods unless a doctor tells you to. Prolonged or heavy use increases the chance of absorption and side effects.
Don’t use povidone-iodine if you know you’re allergic to iodine or to the product’s ingredients. If you get intense burning, swelling, or a spreading rash after applying it, wash it off and get medical help. Avoid getting it in your eyes — rinse immediately with clean water if that happens.
People with thyroid problems should mention povidone-iodine to their doctor. On rare occasions, large or repeated topical use can affect thyroid function because the body can absorb iodine. Pregnant or breastfeeding women should check with their clinician before routine or widespread use.
Do not use povidone-iodine as an internal antiseptic unless a medical professional prescribes a specific diluted solution. Never mix it with other household chemicals. Keep it out of reach of children and store it in a cool, dry place away from direct light.
If a wound is deep, bleeding heavily, shows signs of infection (increasing pain, redness, warmth, pus), or won’t heal, see a healthcare provider. For persistent throat pain, fever, or trouble breathing, get medical attention rather than relying on self-treatment.
