While many people use Betadine (povidone-iodine) as a go-to for minor cuts, experts agree that applying it to open, healing wounds is not recommended. The reason you shouldn't use Betadine on open wounds is that its harsh properties can damage the very cells needed for a swift and complete healing process.

Many common antiseptics are toxic to human cells, not just microbes [1.2.1]. This fundamental cytotoxicity is the primary reason behind the critical question: Why can't antiseptics be used inside the body? Their non-selective nature causes significant harm internally.

Contrary to decades of common practice, medical consensus has shifted significantly regarding first-aid use of hydrogen peroxide. Many modern healthcare professionals now advise against using it on open cuts and wounds, as its cytotoxic effects can do more harm than good and potentially delay healing.

First formulated in 1879, the original Listerine was actually created as a surgical antiseptic and wound cleanser, not a mouthwash. The fascinating story of what happened to original Listerine is one of radical marketing shifts and pharmaceutical repurposing over more than a century of innovation and product diversification.

While povidone-iodine is one of the most effective antiseptics for reducing infection risk, the question remains: Can I use iodine and hydrogen peroxide together? [1.4.1] Combining these common household items is generally not recommended for home first aid as they can neutralize each other and irritate the skin [1.3.2, 1.8.1].

Approximately one-third of the population carries *Staphylococcus aureus* (staph) in their nose without becoming sick. When this strain is methicillin-resistant, it becomes MRSA nasal colonization, which is addressed through a process called decolonization.

Iodine was first discovered in 1811 and quickly gained recognition for its antiseptic properties, a key initial medical use. The question, 'Is iodine considered a medicine?', is complex because it serves both as a vital nutrient and a potent therapeutic agent, depending on its form and application.

For decades, Mercurochrome and Merthiolate were household staples used to treat minor cuts and scrapes, recognizable by their distinct red coloration. But despite their similar names and uses, they were fundamentally different compounds, a distinction crucial for anyone wondering **what's the difference between merthiolate and mercurochrome?**

Proper antiseptic use significantly reduces the risk of infection from needle punctures. The most common liquid used is 70% isopropyl alcohol, which is readily available in convenient, individually wrapped swabs. However, the specific liquid used to clean before injections can vary based on the procedure and clinical setting.

Surgical site infections are a leading cause of hospital-acquired infections, costing billions annually. Selecting the right antiseptic is a crucial component of prevention, and many patients wonder which antibacterial soap is best for surgery.
