In short: povidone-iodine has a broad antimicrobial spectrum and is widely used for skin antisepsis, but can stain and may be affected by organic material. Chlorhexidine (CHG) offers strong, persistent activity and is common for pre-surgical and catheter-site prep, but has specific contraindications (e.g. eyes, ears/middle ear, meninges, and caution in some neonates). The right choice depends on the application and clinical guidelines.

Frequently asked questions

Is chlorhexidine better than iodine?

Neither is universally better — chlorhexidine offers stronger persistence while iodine has a broad spectrum; the best choice depends on the procedure and clinical guidance.

Can povidone-iodine be used before injections?

It is used for skin antisepsis; alcohol prep pads are more common for routine injections because they act fast and dry clean. Follow your protocol.
