What is the difference between antibiotics and antiseptics?

Antibiotics and antiseptics are both antimicrobial substances, but they work in different ways and are used for different purposes.

Antibiotics are drugs that kill or inhibit the growth of bacteria. They are used to treat bacterial infections such as pneumonia, sepsis, and tuberculosis. Antibiotics can be taken orally, injected, or applied topically.

Antiseptics are chemical agents that kill or inhibit the growth of microorganisms. They are typically used to clean and disinfect surfaces, objects, and skin. Antiseptics can also be used as wound cleansers to prevent infection.

The main difference between antibiotics and antiseptics is that antibiotics are systemic drugs that circulate throughout the body, while antiseptics are topical agents that are applied to specific areas. Antibiotics are used to treat infections that have already occurred, while antiseptics are used to prevent infections from occurring.

Some common antibiotics include penicillin, amoxicillin, erythromycin, and tetracycline. Some common antiseptics include hydrogen peroxide, iodine, and chlorhexidine.

It is important to use antibiotics and antiseptics correctly to avoid side effects and drug resistance. Always follow the instructions on the medication label or as directed by your doctor.
