Povidone-iodine, also known as iodopovidone, is an antiseptic topical solution commonly used to disinfect the skin or cleanse minor wounds. It possesses antibacterial properties and is effective against various microorganisms such as amoeba or fungi. Povidone is also commonly used in diluted solutions and as eyedrops. It's crucial to use povidone safely and as directed.
Key Points to Remember
- For minor cuts or wounds, apply a small amount of povidone-iodine directly to disinfect and cleanse the area.
- Create a disinfectant by diluting 1 part povidone with 10 parts distilled or boiled water to cleanse mucous membranes like the mouth or genitals.
- If undergoing an eye procedure, prevent infections such as conjunctivitis by using 1 drop of 5% povidone solution eye drops beforehand.
Step-by-Step Guide
Proper Application of Povidone on Skin
Follow the instructions on the label carefully. Your doctor will prescribe the appropriate amount of povidone for your condition, along with usage frequency, potential interactions, and any special precautions. This information will be detailed on the label and in the accompanying instructions.
- The method of applying povidone can vary based on the type prescribed, such as aerosol sprays, liquid solutions, creams, or saturated pads/swabs.
Thoroughly clean the affected area using a mild soap. If rinsing the area in a sink is challenging, consider sponge bathing the area. Ensure all visible dirt is removed before applying povidone, and pat the area dry with a clean towel afterward.
Apply a small quantity of povidone to the cleaned area. In most cases, a small amount is sufficient to cover the affected area. Follow the provided instructions for pouring the solution, using a dropper, or applying with a cotton ball or swab.
- You can choose to leave the area uncovered or use a sterile bandage, depending on your preference.
- Povidone solutions may cause skin discoloration. Even if not required, a bandage can help conceal any staining.
Monitor for any signs of allergic reactions. Common side effects include mild skin irritation, which should resolve. If irritation persists or worsens, consult your doctor. Seek immediate medical attention for severe allergic reactions such as rashes, hives, itching, or swelling.
- Povidone allergies are uncommon but possible. Familiarize yourself with the allergy symptoms listed on the label or in the instructions.
- Store povidone at room temperature, away from light, heat, and moisture.
Preparing Diluted Povidone for Mucous Membranes
Boil some water. Alternatively, use distilled water if available. Boil tap water vigorously for 10 minutes, then let it cool.
Combine the boiled water and povidone. Use a ratio of 1 part povidone to 10 parts boiled or distilled water. Mix them in a clean container when the water reaches lukewarm temperature.
- If your povidone comes with an eyedropper, each drop equals about 0.05 milliliters (0.0017 fl oz), with 20 drops per milliliter.
- To create 11 milliliters (0.37 fl oz) of diluted solution, mix 1 milliliter (0.034 fl oz) (20 drops) of povidone with 10 milliliters (0.34 fl oz) of boiled or distilled water.
Use a small amount of diluted povidone to flush affected areas. Apply the diluted solution gradually to the affected area, using either a pouring method or an eyedropper. Limit each application to 10 milliliters (0.34 fl oz) for 30 seconds.
- You can flush the area up to four times daily for a maximum of 14 consecutive days.
- For vaginal use, apply the diluted solution once daily for a maximum of 14 days, including menstruation days.
- When using povidone in the mouth or throat, avoid swallowing the solution. This usage is not recommended for children under six years old.
Using Povidone Eye Drops
Wash your hands. Begin by wetting your hands under a faucet and lathering them thoroughly with soap. Ensure you scrub between your fingers, under your nails, and around your wrists for about 20 seconds before rinsing.
- The choice of soap is a matter of personal preference, with any regular hand soap being suitable.
- If clean water isn't readily available, hand sanitizer can effectively clean your hands.
Check the dropper for cleanliness and damage. Avoid using a dropper that is cracked, chipped, or otherwise damaged, as it can lead to incorrect dosage and potential irritation or overdose.
- Avoid touching the dropper with your hands or allowing it to come into contact with any surfaces to prevent contamination.
Tilt your head back and pull down your lower eyelid. Gently pull down on your lower eyelid with your index finger to create a small pocket. Position the dropper over your eye without touching it.
- Keep the dropper close to your eye to minimize waste but avoid contact with the eye itself.
Dispense one drop per eye. Administer eye drops one drop at a time to avoid overuse. Squeeze the dropper gently to release a single drop into the pocket formed by your lower eyelid and eyeball.
- Looking upward can assist in applying eye drops. For steadier hands, support your fingers against your face.
- Using a 5% povidone solution is common before eye surgeries to reduce the risk of developing conjunctivitis.
Remove excess fluid and apply additional drops if needed. After releasing your lower eyelid, close your eyes for approximately two minutes and move them around to distribute the solution. Any remaining fluid can be wiped away with a tissue.
- Follow your doctor's guidance on the number of drops to use. Additional drops should be applied in the same manner as the initial ones.
- If multiple drops are required for one eye, wait about five minutes between applications.
Secure your eyedrops and wash your hands again. Replace the dropper cap without wiping it, then store the eyedrops properly and wash your hands once more.
- The final handwash removes any solution that may have transferred to your fingers during application.
- Keep your povidone stored at room temperature in a place shielded from light, heat, and moisture.

Cautionary Notes
- Avoid using povidone-iodine if you are less than 32 weeks pregnant or if you take lithium. Additionally, individuals with thyroid issues should limit its frequent use.
