BETADINE® Health Answers

Importance of proper wound care and highlights povidone-iodine as a sting-free alternative to alcohol for cleaning, disinfecting, protecting, and supporting wound healing.

Small injuries will always be a part of our lives. From getting a skinned knee as a child to minor accidents in the kitchen, you’re bound to get them every now and then. In fact, one study shows you can even get up to 9,672 minor injuries within your lifetime¹. 

While you can’t avoid them, the next best thing you can do is treat them properly to support wound healing and help prevent further complications, such as sepsis² — a life-threatening disease caused by infection that can shut down your organs. 

One major thing to consider is what to treat your wounds with. Alcohol may be the first thing to come to mind, but the sting that comes with it can be a turn off for a lot of people. We’ve also noted other issues that come with disinfecting with alcohol in a previous blog³. 

In this article, we provide a wound disinfectant alternative to alcohol when it comes to sting-free, proper wound care.

Key takeaways

• Minor injuries are unavoidable and can lead to serious complications like sepsis if poorly managed.

• Alcohol causes pain because it triggers pain-detecting nerve endings in the same way heat does.

• No-sting alternatives to treat wounds exist.

• Unlike alcohol, which cannot eliminate bacterial spores⁵, povidone-iodine provides a sting-free, no-alcohol solution⁹ that kills a wide range of germs based on lab testing.

Why Does Alcohol Sting?

If you’ve ever tried to disinfect your wounds with alcohol, you might have noticed how painful it is upon contact. 

That’s because alcohols like ethanol react with nerve endings that detect pain, called nociceptors⁴. When you place alcohol on a wound, these pain receptors register it in the same way they register heat, thus creating alcohol’s characteristic sting.

Alcohol vs Povidone-Iodine for Wounds

Fortunately, not all disinfectants have that effect during wound treatment. And aside from lacking the characteristic sting, they can also help prevent infection in ways alcohol may not.

According to the Centers for Disease Control and Prevention (CDC)⁵, alcohol can kill active bacteria, fungi, and viruses. However, it may not eliminate bacterial spores, which are structures that help bacteria survive in extreme conditions and stay relatively dormant⁶.

On the contrary, iodophors — or iodine solutions like povidone-iodine — kill bacteria, viruses, and fungi, even certain bacterial spores over prolonged exposure⁷. While they do contain iodine, they don’t carry its irritating effects because iodine is gradually released from the povidone-iodine complex. So aside from being able to curb germs from reproducing, povidone-iodine is also less likely to sting when applied to wounds. 

Povidone-iodine products, then, don’t just clean and disinfect wounds. They also help treat and protect them from further germ growth to help them heal properly.

Proper Wound Care with Povidone-Iodine (BETADINE®)

Aside from lacking the sting, Povidone-Iodine (BETADINE®) Wound Care also provides four wound treatment steps in one: 

1. Cleans: Aside from wound treatment, Povidone-Iodine (BETADINE®) can also be used to clean your wounds.

2. Disinfects: It’s clinically-proven to kill 99.99% of bacteria, fungi and viruses in as early as 30 seconds (based on in-vitro data)⁷.

3. Protects: Its antiseptic property helps protect your wounds against infection.

4. Treats: Povidone-Iodine (BETADINE®) can also help the wound healing process by potentially accelerating tissue repair⁸.

_{Note: Povidone-Iodine (BETADINE®) is not recommended for use in children below 2 years of age.}

_{If symptoms persist, consult your doctor.}
