Description of Povidone iodine:
PVP-I is a complex of PVP with Iodine. It exists as brown-red powder. Povidone iodine has a very low toxicity, but high efficiency. PVP Iodine can kill some bacterial, virus, fungus, mildew and sporule effectively. Povidone Iodine is a stable complex without irritation. PVP Iodine dissolves in water completely, which will make it very easy to use.
Also popular known as Iodopovidone, povidone iodine is used as an antiseptic which is extensively applied on skin topically as a disinfectant prior to and post surgery. Povidone iodine is used as an antiseptic on the skin of patients as well as to disinfect the hands of doctors. It is also importantly used to treat minor cuts and wounds. Povidone iodine will be prepared in both powder and liquid form, Povidone iodine powder and Povidone iodine Solutions. It is listed in the WHO’s list of essential medicines as one of the safest and most effective medicines.
Povidone iodine, PVP-I, is also used in first aid for minor wounds, grazes, cuts, blisters, abrasions and burns. Iodopovidone has a property of being absorbed slowly through soft tissues. Therefore, Povidone iodine is preferred over other disinfectants in lengthier surgeries. It is also used effectively in the treatment of bed sores and vaginitis.
Povidone Iodine 2.5% buffered solution can be used for the prevention of neonatal conjunctivitis. Moreover, Povidone Iodine also works in pleurodesis.
Special Notes: Povidone iodine may lead to skin irritation. It may also cause high level of sodium in blood and kidney problems if used on large wounds. The above is considered as side effects of Povidone Iodine.
