Povidone-Iodine Solution (Betadine)

—Jill Fandrich, PharmD, CRPh

Povidone iodine solution, also known as iodine scrub or iodine prep, is a popular antiseptic used in various medical settings. It contains the active ingredient povidone-iodine, which is a combination of iodine and a water-soluble polymer called povidone. Here are some of the health benefits associated with the use of povidone-iodine solution:

1. Wound disinfection - Povidone-iodine solution effectively prevents and reduces the risk of wound infections. It kills a wide range of bacteria, viruses, fungi, and other microorganisms that can cause infection. Its antiseptic properties make it useful for cleaning and disinfecting cuts, scrapes, and burns.

2. Surgical site preparation - Prior to surgery, povidone-iodine solution is often used to prepare the skin around the surgical site. It helps to reduce the number of bacteria on the skin, minimizing the risk of surgical site infections. This is crucial in preventing complications after surgery.

3. Prevention of infections in medical procedures - Povidone-iodine solution is used in various medical procedures, such as catheter insertion, dialysis, and central line placement, to reduce the risk of infections. Applying the solution to the skin before the procedure acts as a barrier against potential pathogens.

4. Treatment of skin infections - Povidone iodine solution can also treat skin infections, such as impetigo, folliculitis, and ringworm. It effectively kills the bacteria or fungi causing the infection, helping alleviate symptoms and promote healing.

5. Nail infections - Povidone-iodine solution is often used to treat nail infections, such as fungal nail infections or paronychia (infection around the nail). It can be applied topically to the affected area to help fight off the infection.

6. Dental hygiene - This point is extremely important to understand. Povidone-iodine solution is used in oral care to reduce the risk of oral infections. It can be used as a mouthwash or gargle to help prevent and treat conditions such as gingivitis and oral ulcers. It can also be used before dental procedures to minimize the number of bacteria in the mouth. Rinse and gargle (and spit) preventatively or even at the first sign of a sore throat. Povidone-iodine also comes in prepackaged nasal swabs, or you can create your own medicated swab using a cotton tip swab and dousing it with the solution. Do not contaminate the bottle by inserting the tip directly into the solution, and especially remember never to double dip! Swabbing the interior of your nose is beneficial in killing harmful pathogens, and it may even prevent their presence as well.

7. Skin cleansing before procedures - Povidone-iodine solution is widely used to clean and disinfect the skin before invasive procedures, such as injections and blood draws. This helps to prevent the introduction of infections into the body through puncture wounds.

It is worth noting that while povidone-iodine solution has numerous health benefits, it is essential to follow proper usage guidelines and consult with a healthcare professional for appropriate application and dosage.

Investing in your health is paramount, for it is said that a few drops of povidone iodine solution today can prevent a multitude of ailments tomorrow.
