Polyvinylpyrrolidone, usually shortened to povidone or PVP, is a synthetic polymer used in many medicines. It binds tablets together, thickens eye drops, and when combined with iodine it forms the familiar brown antiseptic.

Where Polyvinylpyrrolidone Is Used

Artificial tear drops, as a lubricant
Povidone iodine antiseptic solutions and scrubs
A binder in tablets and capsules
Thickener in gels and lotions

Common Side Effects

Brief blurring after eye drops
Mild stinging
Skin staining and irritation with iodine combinations

Precautions

As an inactive ingredient it is very well tolerated. The precautions that matter belong to whatever it is combined with, and povidone iodine in particular should not be used extensively in pregnancy, on newborns, or by people with thyroid disease without advice, because iodine is absorbed. Allergic reaction to povidone iodine is possible and needs the product stopped.
