Povidone-iodine: Uses, Dosage, Side Effects and More

Introduction: What is PovidoneIodine?

Povidoneiodine is a broadspectrum antiseptic used for skin disinfection and wound care. It is a complex of iodine and a polymer called povidone, which helps to solubilize iodine, making it more effective and less irritating to the skin. Povidoneiodine is commonly found in various forms, including solutions, ointments, and swabs, and is widely used in both medical and home settings.

Uses of PovidoneIodine

Povidoneiodine is approved for several medical uses, including:

1. Surgical Preparation: It is used to disinfect the skin before surgical procedures to reduce the risk of infection.
2. Wound Care: Povidoneiodine is effective in cleaning minor cuts, scrapes, and burns to prevent infection.
3. Infection Control: It is used in hospitals to disinfect surfaces and equipment.
4. Oral Rinse: In diluted form, it can be used as a mouthwash to treat oral infections.
5. Vaginal Antiseptic: It is sometimes used to treat vaginal infections.

How It Works

Povidoneiodine works by releasing iodine, which has potent antimicrobial properties. When applied to the skin or mucous membranes, it penetrates the cell walls of bacteria, viruses, and fungi, disrupting their cellular functions and leading to their destruction. This action helps to prevent infections in wounds and during surgical procedures.

Dosage and Administration

Povidoneiodine is available in various forms, and the dosage depends on the specific use:

• Topical Solution: For skin disinfection, apply a sufficient amount to the affected area 1-2 times daily.
• Ointment: Apply a thin layer to the wound 1-2 times daily.
• Oral Rinse: Dilute with water (usually 1:10) and swish in the mouth for 30 seconds, then spit out. Use 2-3 times daily as needed.

Always follow the instructions provided by your healthcare provider or the product label.

• Thyroid dysfunction (especially in those with preexisting thyroid conditions)

If you experience any severe side effects, seek medical attention immediately.

Drug Interactions

Povidoneiodine may interact with certain medications, including:

• Lithium: Povidoneiodine can affect thyroid function, which may alter lithium levels.
